:WTF: Okay, have any of you people that are giving advice actually ever OWNED a Modestus? I can tell you for a fact that three Bronze/Avacodo puffers will NOT fit in a 30G tank.

Neither will two.

They are very aggressive toward conspecifics, and cannot be kept with other puffers.

I have one in my 100G, and he's a little bigger than 4 inches. One of the correct things I read on this thread was that their teeth grow quickly (they do).

Please, people, do your homework, or at least don't give advice about a fish that you don't know that much about. Sorry if I offended anybody, but it is just plain irresponsible to suggest something that can cause problems.
