I've had a beautiful dwarf gourami for about a week who appears healthy (and not blind,) but he has a severe depth perception problem when he feeds. He lunges everywhere but at the food -- an inch in front of it, to the left, to the right. He eventually manages to accidently make contact with a flake or two. Short of hand-feeding him, or overfeeding the tank to be sure he eats, do you have any suggestions for me on how or what I can feed him to be sure he doesn't starve?
