My neighbor made me take his pufferfish from him today. He said he was going to kill it if I didn't take it so I had no choice. I tried taking it to the LFS but they would not take it! Petsmart and petco won't take it either so I put it in my 5 gallon betta tank and put my betta in my 10 gallon for now. I have no idea how to take care of a pufferfish can somebody please help me? The puffer is a figure 8 puffer by the way.
