My alli snapper is having trouble submerging and getting to the bottom of the tank. I use that Sulfa bath stuff and have given him several treatments of it. It appears that after his bath he is ok for a day or two. However, eventually he starts to float again and really has to fight to swim to the bottom. This has been going on and off for about a month now. I made an appointment with a vet but then i called it off because it looked like he was better. Sure enough though, he started floating again. I gave him another bath and he has been fine for the last couple of days but I am thinking that it might start up again tomorrow or sometime this week. Other than that he is behaving normally. He eats a lot and gets along very well with his tank mates. He's just a baby and I want to do whats best for him. If anyone has any experience with this please give me some advice. I would prefer treating it myself and avoid taking him to the vet unless I have to. Thanks!
