I bought a new leopard puffer about a week ago. all he does is lay around on the bottom. He is a ugly brown color except when he finally does swim. He has been eating good until today. His breathing looks fast to me. I thought he was dying a while ago so I moved the plant that was beside it and my puffer puffed. That was about 45 min to 1 hour ago and he is still puffed. Does anyone know how long they stay like that or what I can do to help him. I dont want him to die. By the way I checked his water with a test strip and everything was normal. Help!!!
