If a fish has not grown much because of being kept in less-than-ideal conditions, can it recover and continue to grow if moved to a cleaner tank? My buddy is trying to get me to take a couple of fish off his hands because he doesn't have the time to maintain them. He has a trio of silver dollars and two cichlids (I think jaguar and dempsey). I already have some SDs in my tank so adding to my school would be nice. I dont know about the cichlids tho. These fish havent grown in about two years, and I am guessing thats because he doesnt do regular maintenance or feeding. If I can make them happy will they ever grow again? Obviously I would quarantine before adding to my main tank.
