i am a novice and I think I made a big mistake. I put a small powder brown in my nano 28g. I have a clown and a dottyback. I really should have done my homework before I purchased him. He has acclimated to my tank and plays well with the others. I'm thinking about a bigger tank but how soon should I do this? I don't want my brown to die. Do I have a few months or should I try and sell him or maybe see if the shop will take him back? Please advise.
