So i somehow ended up with 2 clown plecos, bad choice.. well one of their tail has been chewed up and was wondering if it could be the other clown pleco? or the dwarf cockatoos?.. i did split them up into different tanks now, the torn up tailed clown is sittin in a 20 gallon long with 5 cherry barbs, would this tank be enough to house this guy? also what will help grow his tail back? is there some type of fin healers i can pick up?? im not realy sure if the tail was torn up with i bought it or not... hopefuly it will grow back cause it sure looks creepy with a missing tail..
