Freshwater puffer?

well if you like puffers, those are usually brackish. dwarfs, i have been told are the more hardier, but others like figure 8 and leopard those are bigger. and if you are really interested in brackish i would have to say, bumblebee gobies (small only about 1 1/2 max) a href="http://www.aqualandpetsplus.com/Oddball,%20Bumblebee%20Goby.htm" rel="nofollow"http://www.aqualandpetsplus.com/Oddball,…/a and and MAYBE a freshwater flounder, then get pretty big a href="http://www.aqualandpetsplus.com/Oddball,%20Flounder.htm" rel="nofollow"http://www.aqualandpetsplus.com/Oddball,…/a
