The Mauritius anemonefish ( Amphiprion chrysogaster ) lives in the lagoons and coral reefs on the coast of Mauritius , possibly also in Réunion at depths of 2 to 40 meters. Like all anemonefish, it lives in close symbiosis with some large sea anemone species . As host anemones it accepts the glass bead anemone ( Heteractis aurora ), the magnificent anemone ( Heteractis magnifica ), the corkscrew anemone ( Macrodactyla doreensis ), the carpet anemone ( Stichodactyla haddoni ) and Mertens anemone ( Stichodactyla mertensii ).
features
The body of this damselfish is dark brown, almost black on the flanks, the breast, the snout region and the pectoral fins are orange. The caudal fin is black with white borders. The very similar Seychelles anemonefish ( Amphiprion fuscocaudatus ) has a black and white striped caudal fin. The anal fin can be yellow-organic or black. Two broad, white horizontal stripes run across the body, the first directly behind the eye, the second starting in the middle of the dorsal fin . Another transverse ligament, which is more than three rows of scales wide, separates the caudal fin from the caudal fin stalk. In the similar, Central Pacific three-banded anemonefish ( Amphiprion tricinctus ) it is less than three scale widths. Mauritius anemonefish, which live in symbiosis with Stichodactyla mertensii , are mostly completely black, with the exception of the white transverse bands.
The dorsal fin has ten hard and 16 to 17 soft rays, the anal fin has two hard and 13 to 14 soft rays. The pectoral fins are supported by 20 to 21 rays. On the first gill arch there are 18 to 20 gill trap processes. Amphiprion chrysogaster becomes 11.5 to 15 centimeters long. The length is 1.9 to 2.1 times the body height. The sideline is accompanied by 35 to 42 scales.
