We've been re-arrangeing some tanks.. and have actually weeded out most of our community fish down to a couple of solitary fish. always been interested in puffers but never wanted to deal with Brackish/Saltwater. At work we've had a lil' terror of an avacado puffer who's been there for quite awhile, and we just got in a Fahaka.. I'm seriousely debating picking up either or of these guys. Which one would you pick? any why? I know enough about both species I think to be capable of careing for either. But what are some real pros and cons of each? I find them equally intreagueing as fish. btw the Fahaka is approx 2" if that, and the Avacado is approx 3-4".
