Most stores mislabel fish, just hope yours is pretty good at not renaming. The ONLY fish I have ever seen renamed at my good LFS was a frogmouth catfish they had labeled as "prehistoric catfish". They said it slipped in with another order so I told them what it was but they never changed it. If I had a tank for it I would get it since I feel bad for it in about a little 15 gallon with gill curl. Also I feel places like petco shouldn't even be allowed to sell fish, I know they don't have the same appeal as cats or dogs but they are all animals and deserve to be treated equally!
