He does look a lot like that but the fish I have it with are scaleless except my bichirs, so should i return him to the store?c He seems to be eating as his stomach doesnt look empty.tetraodon_biocellatus said:He almost looks like a wasp goby or something, if so he may just need a higher salinity (brackish fish). They do swim a bit oddly but he does look rather sickly, if you move him to a brackish tank you may have better luck feeding him.
good luck
^butterfly/wasp goby (not an actual goby)
