No, it's not the only fish in that tank. I don't really have any hiding spots besides the powerhead(which it sometimes hide behind but still stable when it hidesEgon;4593604; said:Looks great. Is that the only fish in the tank? Is there any hiding spots for him? I'm asking because I have 10 2" indos in a 180. Half are stable and half are not? Tank is sand bottom with a lot of drift wood for hiding. Aggression seems to be evenly distributed across all fish. Just odd some are stable and some are not???
