good morning, i need a little help, i have this fish (age 1) and he seems depressed but he hasnt always been like it, he stays in the corner on the floor of the tank most of the time although he does have a little swim every so often. hes eating ok, he's not being picked on, the tank has plenty of room, he has no signs of tail rot, white spot, swim bladder, well, he looks fine. although he isnt growing as fast as the identical fish i bought at the same time. infact the other fish is twice his size. i have 6 fish in total and the rest are really healthy. please can anyone help, i wouldnt want to loose one half of jedwood
