He’s a freshwater,very small (2″) and I put him in a 40 gallon established tank with two Angelfish (2″) that’s it.His problem is that he hides all day…..he wants to hide so bad that he’ll almost be sideways against any little cubbyhole in the tank.I don’t think he’s sick because he will dart out to feed on frozen brine shrimp that I feed twice a day.Should I go back to the store and buy another one to be his friend?I take good care of my fish,and please don’t say I’m abusing them for some idiotic reason because of your self righteous attitude.Now that’s out of the way,I would appreciate your reply.
