I have seen these cute little puffers at Petsmart. I was wondering if they would do well in a 29 gallo tank with 1 blue gourami, 2 mollies, 2 mickey mouse platys. I don't remember the name of the little things but the were about 1/2 in. long and greenish/brown. I didn't know if they would go well or not. I also have 6 gal. tank with 2 guppies and 1 ADF. Would it be ok in there? Also what do they eat? Flake food?
