I have a 29g, planted, 3 dwarf puffers, 5 dwarf gourami's, plus a small pleco and 3 otto cats. 2 of the puffers and the other fish seem fine, however the third puffer doesnt look so well. dont know if the 3 are male or female. the sick one seems to swim with a slight "list" to one side, hangs near the top and doesnt seem to want to go deep in the tank tho I have seen it is capable of going deep still (possible swim bladder issue??). also the back seems to be overly arched and the tail sticking higher up than normal. the three are fed well and each have little pot-bellies (frozen and freez-dried blood worms, frozen mysis, mostly, with occasion ramshorn snails)
