Bought a molly for my little brother to start his tank. He was in perfect condition at the pet store. Then we brought him home and now he sits in the corner of a 1 gallon tank. Could he be depresed i thought maybe because he is a social fish he wanted companny so i put a male swordtail and a tiny snail. To much for a 1 gallon should i put both in my community tank. Plz HELP!
