I'm thinking of getting a Pig-Nosed Puffer and putting it in its own tank (I know just by looking at them that they would probably eat ME if I was in that tank). I simply enjoy how horrible and ugly and evil these fish are, and I want one! I have a 20 gallon that I will cycle and overfilter before adding the fish. I know he'll need live and crunchy food for his teeth and sand so he can burrow and be generally antisocial. Anything else I've missed or need to know before I start setting up and cycling his tank?
