So I have a 40 gallon tank set up, just about finished cycling. I really want to get a puffer, always though they were cool fish. I was thinking of getting a green spotted puffer, when I went into my lfs yesterday the guy there showed me some avocado puffers they just got in, he said they had way better personalities than the gsp. Now I'm not sure which type I want to get. Anyone with experience keeping puffers able to weigh in on which species they prefer?
