At the lfs they had it under rainbow pike it is it is gray and has a purple center, i hope that helps its about 5 to 6 inches it is currently in a 75gal with 3 sev. that are about 4in. after looking at profiles i think i have a Crenicichla lugubris does anybody have any good advice in regards of tankmates i can move my sev. to a different tank.
