The '''clown loach''', ''Chromobotia macracanthus'', is a [[tropical]] [[freshwater]] [[fish]] belonging to the [[Cobitidae]] (loach) family. It is the sole member of the ''Chromobotia'' genus. It originates in inland waters in [[Indonesia]] on the islands of [[Sumatra]] and [[Borneo]]. It is a popular fish in the freshwater [[aquarium]] trade and is sold worldwide. <ref name="fishbase">{{fishbase species|genus = Chromobotia |species = macracanthus | month = April | year = 2007 }}</ref>

==Taxonomy and naming==
The fish was first described as ''Cobitis macracanthus'' by [[Pieter Bleeker]] in 1852. In 1989, the scientific name was changed to ''Botia macracanthus''.<ref name="wetpetz">{{cite web|url=http://www.wetpetz.com/clownloach.htm | accessdate=2007-08-17| title = Clown Loach | publisher = WetPetz.com | year = 2004}}</ref> In 2004, [[Maurice Kottelat|Dr. Maurice Kottelat]] split the ''[[Botia]]'' genus, containing 47 different species, into seven separate [[genus|genera]], resulting in the clown loach being placed into a genus of its own, ''Chromobotia''.<ref name="kottelat04">{{cite journal|title = ''Botia kubotai'', a new species of loach (Teleostei: Cobitidae) from the Ataran River basin (Myanmar), with comments on botiine nomenclature and diagnosis of a new genus | author = Kottelat, Maurice | journal = Zootaxa | volume = 401 | pages = 1–18 | year = 2004 | url = http://www.mapress.com/zootaxa/2004f/z00401f.pdf | format = PDF - abstract only| issn = 1175-5334 | accessdate=2007-08-17 }}</ref>

The genus ''Chromobotia'' derives its name from the [[Greek (language)|Greek]] word ''chromo'', meaning "colour", and the regional Asian word ''botia'', meaning "warrior" or "soldier". The [[specific epithet]] ''macracanthus'' is derived from the Greek word ''macros'', meaning "large" and the [[Latin]] word ''acanthus'', meaning "thorny", referring to the large spines below the fish's eyes. The "Clown loach" common name comes from the fish's bright colors resembling a clown's makeup, and the fish's ability to entertain observers with its comical behavior when kept in an [[aquarium]].<ref name="wetpetz"/>

==About RfB==
==Description and behavior==
{{Wikipedia:Requests for adminship/bureaucratship}}
Information about the maximum size of the clown loach varies, with some estimates ranging from 11 to 14 [[inch]]es (40 to 50 [[centimetre|cm]]), and with typical adult sizes ranging from 7 to 10 inches (15 to 20 cm).<ref name="ahlander">{{cite web | url = http://www.bollmoraakvarieklubb.org/artiklar/praktbotia/clown%20loach.htm | title = Clown loach ''Chromobotia macracanthus'' (Bleeker 1852) | accessdate = 2007-08-18 | publisher = www.bollmoraakvarieklubb.org | author = Âhlander, Ola | date = [[2 September]] [[2004]]}}</ref> The fish's body is long and laterally compressed, with an arched [[Dorsum (biology)|dorsal]] surface and a flat [[ventral]] surface. Its head is large and its mouth faces downward with thick, fleshy lips, and four pairs of [[Barbel (anatomy)|barbels]]. The barbels on the lower jaw are small and difficult to see.


==Current nominations for bureaucratship==
The body is whitish-orange to reddish-orange, with three thick, black, vertical bands. The first band runs from the top of the head and through the eye. The second band lies between the head and the [[dorsal fin]], and wraps around to the belly, and the third band covers the start of the [[caudal peduncle]] and extends to the [[anal fin]]. There is some regional color variation in the species; the pelvic fins on fish from [[Borneo]] are reddish orange and black, while the pelvic fins on fish from [[Sumatra]] are entirely reddish orange.<ref name="loaches1">{{cite web | url = http://www.loaches.com/articles/clown-loach-coloration-marking-variations | title = Clown Loach Coloration & Marking Variations | author = Thoene, Martin | date = [[13 August]] [[2007]] | accessdate = 2007-08-18 | publisher = Loaches online }}</ref>

The fish has a movable spine that lies in a groove below the eye, which may be extended as a defense mechanism. The spine may cause a painful wound, but is not venomous.

==Distribution and habitat==
Clown loaches originate in [[Indonesia]], on the islands of [[Sumatra]] and [[Borneo]]. For the greater part of the year, the fish lives in murky or blackwater rivers and lakes, but breeding adults migrate to smaller waterways to spawn annually.<ref name="ahlander"/> They are especially predominant in the flood plains of the hill country.<ref name="badman">{{cite web | url = http://badmanstropicalfish.com/profiles/profile13.html | title = Clown loach profile | publisher = Badman's Tropical Fish | accessdate = 2007-08-18}}</ref>

In its native habitat, the fish is found in water with a temperature range of 77 to 86 [[Fahrenheit|°F]] (25 to 30 [[Celsius|°C]]), a [[pH]] between 5.0 and 8.0, and water hardness between 5 and 12 [[dH]].<ref name="fishbase"/>

==In the aquarium==
A seemingly harmless, very active, social fish, they are best kept in groups of 5 or more and due to their potential size a 100 gallon aquarium should be the minimum size used. They also associate themselves easily with [[Panda corydoras]] and school together in currents. These fish have bifurcated subocular (located under the [[eye]]s) spines, which are used as a defence mechanism. If a loach deploys its spines while caught in a net, untangling it is difficult and can cause severe injury. It is also a good idea when moving larger specimens to double or triple bag them or use a solid container. Some owners have been stabbed while trying to catch or touch these fish. When kept in groups smaller than 5, they may spend more time hiding under obstacles in the water. [[Tiger barb]] also will associate very well with clown loaches, and they may school together. the tiger barbs will act in the same way as the loaches if they shoal, and vise versa.

They are also found to make clicking noises when excited or eating. This sound comes from the grinding of their [[pharyngeal teeth]]. Sometimes they lie on their sides on the bottom of the tank or swim upside down and appear to be dead. This is a common event and the aquarist should be aware of this fact or unnecessary removal may occur.

If you have noticed that your clown loaches do not come out of hiding, there are some easy things to adjust so that your clown loaches will be more comfortable. A good tank setup for a clown loach should include ample shade, real plants, hiding places and other peaceful fishes. Make sure the environment is not too bright initially. Provide shade from tank lighting. The tank should not be next to a window unless ample shade is provided. Window tanks with ample sun will allow Chromobotia to warm themselves and do their dominant color dances with more splendor as they flash in and out of sunlight slicing through opeings in natural cover. An example tank will have a powerhead to create a current for them to swim against as well as cover to stay under while doing so - think clear water mountain brook with current rushing from cascades deep beteween boulders. In fact, Clowns show a strong preference for larger rocks taken directly from mountain streams too swift to allow algae growth. They will peck at these rocks often and always sleep under and on them.

Clown loaches are keen observers of other fish in the aquarium; they observe and react accordingly. If other fish are skittish and hide, clowns will observe this and do the same. Make sure that other fish in your community tank are docile and not prone to hide. Chromobatia will all sleep together under their favorite collection of stream rocks. When other fish absently enter that territory and dither too long, the clowns will occassionaly react with a swarm behavior at which time (unfortunately) the errant straggler will experience with lethal outcome the thorns that give the Clown its second name, Thorny Eyes. We find that all-orange fish are prone to mass kill-offs regardless of where they swim, and this may have something to do with Tiger botia’s domainace color displays. However, overly inquisitive Glass Tetra and small slow-moving catfish can also fall victim. If the killed fish are not removed, the Clown pack will move the kill a short distance from the lair and wait until the fish decays into a white blob when it is rapidly consumed. Sometimes they cannot wait and will open the gut cavity with their thorns and mouths and immediately eat the victims guts and vital organs, something scaleless algae eaters may be most prone too. We have tried Beta (also an agressive species) with Botia and it is clear that safety in numbers holds true: the Beta will quickly begin to fray and need to be removed. Chromobotia do not seem to attack same-size or larger fish or any fish that keep away from their chosen lair. Perhaps Borneo mountain people who know the fish better could describe Chromobotia’s predation more accurately.

Because clown loaches come from [[rivers]] and streams, they are accustomed to having other fishes and plants in their environment. Not having plants and/or other fishes can cause clown loaches to become stressed and to go into hiding. Especially on introduction to a new tank, it is imopirtant that lots of placid, active smaller fish are present. Until you know what fish company they like best, use many colors and varieties of inexpensive minnows. Another important thing to remember is that since they do come from a fast moving river environment, they need a tank with lots of clear, well filtered and fast moving water which can be achieved with proper filtration and the use of powerheads. Stream rocks should allow resting back eddies as well as shade and cover.

[[image:ClownLoachesWithIch2.JPG|thumb|right|Two juvenile clown loaches with [[Ichthyophthirius multifiliis|ich]]. Characteristically, for this stage of infestation, both are hiding in an ornament.]]
Before introducing clown loaches to your tank, make sure the fish you currently have are compatible because aggressive fish will stress your clown loaches and may need to be removed. Clown loaches are particularly susceptible to [[Ichthyophthirius]] (ich), so they must be watched closely when initially introducing them to a tank and when new fish are added. Ich usually deals the typical clown loach a poor prognosis since the standard treatment is especially toxic to the clown's "skin-type" and the dose must be halved and is therefore less effective.

A variety of food should be provided for clown loaches, and their behaviour should be observed during feeding. In a [[community tank]] other fish may take the food before it reaches the bottom, where the clown loaches feed. Most clown loaches accept commercial flake food and sinking pellets as their dietary staple, but thrive with a variety of food: live (worms, brine shrimp, small snails), plant matter, freeze-dried ([[tubifex worm]]s, especially if it is fortified) and frozen [[brine shrimp]] (always thaw frozen food to aquarium temperature).

Clown loaches are also regarded as a natural way of controlling an infestation of small [[snail]]s in the aquarium. This being said, a person considering them for this purpose must also consider their future needs with regard to a large aquarium. A person getting clowns to remove snails in a smaller tank might be better served with one of the many other botia species that are as effective at the task but remain much smaller. Despite that utilitarian purpose, clown loaches are usually kept for reasons of appearance and personality.

Requests for adminship (RfA) is the process by which the Wikipedia community decides who will become administrators (also known as admins), who are users with access to additional technical features that aid in maintenance. Users can either submit their own requests for adminship (self-nomination) or may be nominated by other users. Please be familiar with the administrators' reading list, how-to guide, and guide to requests for adminship before submitting your request. Also, consider asking the community about your chances of passing an RfA.

This page also hosts requests for bureaucratship (RfB), where new bureaucrats are selected.

If you are new to participating in a request for adminship, or are not sure how to gauge the candidate, then kindly go through this mini guide for RfA voters before you participate.

There is an experimental process that you may choose to use to become an administrator instead of this process, called administrator elections. Details are still being worked out, but it is approved for one trial run which will likely take place in 2024.

About administrators

The additional features granted to administrators are considered to require a high level of trust from the community. While administrative actions are publicly logged and can be reverted by other administrators just as other edits can be, the actions of administrators involve features that can affect the entire site. Among other functions, administrators are responsible for blocking users from editing, controlling page protection, and deleting pages. However, they are not the final arbiters in content disputes and do not have special powers to decide on content matters, except to enforce the community consensus and the Arbitration Commitee rulings by protecting or deleting pages and applying sanctions to users.

The community grants administrator access to trusted users, so nominees should have been on Wikipedia long enough for people to determine whether they are trustworthy. Administrators are held to high standards of conduct because other editors often turn to them for help and advice, and because they have access to tools that can have a negative impact on users or content if carelessly applied.

Nomination standards

The only formal prerequisite for adminship is having an extended confirmed account on Wikipedia (500 edits and 30 days of experience).[1] However, the community usually looks for candidates with much more experience and those without are generally unlikely to succeed at gaining adminship. The community looks for a variety of factors in candidates and discussion can be intense. To get an insight of what the community is looking for, you could review some successful and some unsuccessful RfAs, or start an RfA candidate poll.

If you are unsure about nominating yourself or another user for adminship, you may first wish to consult a few editors you respect to get an idea of what the community might think of your request. There is also a list of editors willing to consider nominating you. Editors interested in becoming administrators might explore adoption by a more experienced user to gain experience. They may also add themselves to Category:Wikipedia administrator hopefuls; a list of names and some additional information are automatically maintained at Wikipedia:List of administrator hopefuls. The RfA guide and the miniguide might be helpful, while Advice for RfA candidates will let you evaluate whether or not you are ready to be an admin.

Nominations

To nominate either yourself or another user for adminship, follow these instructions. If you wish to nominate someone else, check with them before making the nomination page. Nominations may only be added by the candidate or after the candidate has signed the acceptance of the nomination.

Notice of RfA

Some candidates display the {{RfX-notice}} on their userpages. Also, per community consensus, RfAs are to be advertised on MediaWiki:Watchlist-messages and Template:Centralized discussion. The watchlist notice will only be visible to you if your user interface language is set to (plain) en.

Expressing opinions

All Wikipedians—including those without an account or not logged in ("anons")—are welcome to comment and ask questions in an RfA. Numerated (#) "votes" in the Support, Oppose, and Neutral sections may only be placed by editors with an extended confirmed account[2] and only after the RfA has been open for 48 hours.[3]

If you are relatively new to contributing to Wikipedia, or if you have not yet participated on many RfAs, please consider first reading "Advice for RfA voters".

There is a limit of two questions per editor, with relevant follow-ups permitted. The two-question limit cannot be circumvented by asking questions that require multiple answers (e.g. asking the candidate what they would do in each of five scenarios). The candidate may respond to the comments of others. Certain comments may be discounted if there are suspicions of fraud; these may be the contributions of very new editors, sockpuppets, or meatpuppets. Please explain your opinion by including a short explanation of your reasoning. Your input (positive or negative) will carry more weight if supported by evidence.

To add a comment, click the "Voice your opinion" link for the candidate. Always be respectful towards others in your comments. Constructive criticism will help the candidate make proper adjustments and possibly fare better in a future RfA attempt. Note that bureaucrats have been authorized by the community to clerk at RfA, so they may appropriately deal with comments and !votes which they deem to be inappropriate. You may wish to review arguments to avoid in adminship discussions. Irrelevant questions may be removed or ignored, so please stay on topic.

The RfA process attracts many Wikipedians and some may routinely oppose many or most requests; other editors routinely support many or most requests. Although the community currently endorses the right of every Wikipedian with an account to participate, one-sided approaches to RfA voting have been labeled as "trolling" by some. Before commenting or responding to comments (especially to Oppose comments with uncommon rationales or which feel like baiting) consider whether others are likely to treat it as influential, and whether RfA is an appropriate forum for your point. Try hard not to fan the fire. Remember, the bureaucrats who close discussions have considerable experience and give more weight to constructive comments than unproductive ones.

Discussion, decision, and closing procedures

Most nominations will remain active for a minimum of seven days from the time the nomination is posted on this page, during which users give their opinions, ask questions, and make comments. This discussion process is not a vote (it is sometimes referred to as a !vote, using the computer science negation symbol). At the end of the discussion period, a bureaucrat will review the discussion to see whether there is a consensus for promotion. Consensus at RfA is not determined by surpassing a numerical threshold, but by the strength of rationales presented. In practice, most RfAs above 75% support pass.

In December 2015 the community determined that in general, RfAs that finish between 65 and 75% support are subject to the discretion of bureaucrats (so, therefore, almost all RfAs below 65% will fail). However, a request for adminship is first and foremost a consensus-building process.[4] In calculating an RfA's percentage, only numbered Support and Oppose comments are considered. Neutral comments are ignored for calculating an RfA's percentage, but they (and other relevant information) are considered for determining consensus by the closing bureaucrat.

In nominations where consensus is unclear, detailed explanations behind Support or Oppose comments will have more impact than positions with no explanations or simple comments such as "yep" and "no way".[5] A nomination may be closed as successful only by bureaucrats. In exceptional circumstances, bureaucrats may extend RfAs beyond seven days or restart the nomination to make consensus clearer. They may also close nominations early if success is unlikely and leaving the application open has no likely benefit, and the candidate may withdraw their application at any time for any reason.

If uncontroversial, any user in good standing can close a request that has no chance of passing in accordance with WP:SNOW or WP:NOTNOW. Do not close any requests that you have taken part in, or those that have even a slim chance of passing, unless you are the candidate and you are withdrawing your application. In the case of vandalism, improper formatting, or a declined or withdrawn nomination, non-bureaucrats may also delist a nomination. A list of procedures to close an RfA may be found at WP:Bureaucrats. If your nomination fails, then please wait for a reasonable period of time before renominating yourself or accepting another nomination. Some candidates have tried again and succeeded within three months, but many editors prefer to wait considerably longer before reapplying.
