The seagrass or seaweed filefish ( Acreichhys tomentosus ) lives in the tropical Indo-Pacific from the coast of East Africa to Fiji , north to the Ryūkyū Islands and south to New South Wales and Tonga .

features

It becomes 10 to 12 centimeters long and has a relatively high, rhombic body shape. The color is gray or brownish with large dark spots. The fish can change their color if necessary and also make the spots disappear. Stressed or sick animals turn green. The first dorsal fin spine is isolated, greatly enlarged and serrated. Males have a Velcro-like zone of glandular skin appendages on the base of the tail, as well as an indentation between the pelvic and anal fin

Fin formula : dorsal 27–30, anal 26–29

Way of life

Seagrass filefish live mainly in seagrass meadows and between algae stocks near coral reefs, but also in protected lagoon reefs at depths of one to 25 meters. Usually they are loners, less often they live in pairs. Among other things, they feed on amphipods , polystyrene and mollusks .

Reproduction

The reproduction of the seagrass filefish is known from an initial breeding in the aquarium described in 2008. The fish spawn on the open sandy bottom, the female takes care of the brood. The eggs are constantly fanned with the pectoral fins in order to supply fresh water and intruders into the breeding area, including the male, are driven away. The larvae hatch after three days and are then about 2.7 mm long. They develop very quickly. From the 10th day the metamorphosis into juvenile fish begins , after 4 months they are already 4 cm long.

Aquaristics

The seagrass filefish is imported as an aquarium fish because of its pleasant property for saltwater aquarists to eat the glass roses and fire anemones , which are perceived as harmful . The willingness to eat small sea anemones, however , varies from person to person and the fish can also eat giant clams , tube worms , large polyp stony corals or certain soft corals . Small polyp hard corals seem safe from them.
