The red-stripe calf fish ( Aphyosemion elberti ) is a colorful representative of the killifish native to the waters of Cameroon , eastern Nigeria and western central Africa .

features

The red-stripe fig fish is a slender, medium-sized tooth carp . Both males and females reach a standard length of 4 cm. Males generally have an olive-green to brown back and bright blue to blue-green sides of the body, on which numerous red spots appear, which are arranged as irregular, horizontal bands on the front half of the body and as vertical stripes on the back half of the body. The number and width of the stripes are variable between the different populations. The dorsal and anal fins are light blue with red stripes and dots. In the case of a yellow morph , these fins have a wide yellow to yellow-orange edge, which can also be missing in the dorsal fin. The caudal fin is light blue with vertical, red stripes in the center and horizontal, red stripes on the upper and lower edge. These stripes can be yellow on the yellow morph. Females are gray-brown and show a pattern of dark brown spots and stripes that are arranged similarly to the red ones in the males. Their unpaired fins are colorless, light yellow or orange with dark red-brown spots. The caudal fin has faint horizontal stripes.

distribution

The red-stripe fig fish occurs in small streams, rivers and swamps in open and dry grasslands and savannas. In the Adamaua highlands in northern Cameroon lie the catchment areas of the upper Benue , a tributary of the Niger , the upper Logone , which flows into Lake Chad via the Shari , as well as the Sanaga and its tributary Mbam . In the upper reaches of these rivers, which flow through the national territories of Cameroon, Nigeria, the Central African Republic and Chad, the red-striped carrot is native.

Taxonomy

The red-stripe calf was first described by Ernst Ahl in 1924 under the name Panchax elberti . In the same year, George Sprague Myers, who was only 19 at the time, established the genus Aphyosemion , to which the splendid red-stripe carrot is now counted. Also in 1924, Ahl had presented and described the magnificent female Panchax bualanus in issue 1–2 of the Zoological Scoreboard . However, in 1968 JJ Scheel came to the opinion that the two specimens were the same species and therefore the name Panchax bualanus or Aphyosemion bualanus should be preferred to the species name Panchax elberti because of the earlier publication by Ahl according to the priority rule . For a long time, the red-stripe fig was known under the name Aphyosemion bualanus , until the opinion prevailed from 1988 that there were two different species. L. Seegers was able to compare the type specimens Ahls in the Zoological Museum in what was then East Berlin and came to the conclusion that the two types of fish could be clearly distinguished.
