Have any of you have experience with these. I just bought one and he is fine with the rest of the fish in the 20 gallon tank but he is turning brown. He is a figure 8 spotted puffer. I do not know if this is natural or if he is sick.
I did a lot of research and talked to two fish stores. He was fine in the tank with the others, he hated my loach though which I was fine with because my loach terrorizes everyone else in the tank. He bit his tail in half, but that was about it. The sad thing was he was sick and died yesterday. It's a beautiful fish and I recommend it to anyone interested. It was fine with almost everyone.
