Hey guys, I've posted before about puffers, but I'm still not sure which direction i want to take my 40g tank. I've been reading conflicting information on the net about which puffer species are truly freshwater and which aren't.

I've been told so far that Dwarf Puffers, Hairy Puffers, and Figure 8's are the more common FW species.

Do you guys have any stocking recommendations as to which FW species including ones I haven't mentioned I could make work in my 40g?
