I have 3 Green Spotted Puffer fish in a 30 gallon aquarium. Who else owns this type of fish? Do you have any other fish in the same tank? I had some bumble bee gobies, but they were eaten about a month later. It seems like they will eat just about any other kind of brackish fish out there. I feed them brine shrimp, guppies, and worms from outside, along with snails. What do you feed yours and do you grow your own snails? How? Any other cool information you would like to share about them?
