it is callled a pristella tetra, they get 1.5", look them up, they are not slender, they have oval bodies, i didn't think a firemouth could eat anything this big. And at least not soon. Oh an i just bought 2 more cories, another that is light with small dark spots, and a dark brown dorsal and a just plain gray one With further inspection, the gray one did not look to good, now i can see small white spots on it. GREAT! now i got to treat my tank for ick! i hate this disease. all of the other fish are very lively and healthy though, so i hope no one else gets it and this new guy heals up good. Ive allready begun treatment.
