Hey i have a flowerhorn who lies on the bottom sometimes but when he sees me he feels like 1 mil bucks. He looks healthy and eats and acts normal he just got cured of swim bladder disease and fin rot. He has no gravel in his tank or anything. He has a flowerhorn male next to him in a different tank and he acts if hes not even there. I had him for about a year now and he looks depressed. Should i get a mirror or one of those flowerhorn toys where the flowerhorn attacks the toy?
