Real new to this hobby but fwiw, I have a green spotted puffer in my 90 gal. I got him about two weeks after i set up my tank. Got the salt level up over the next month or so. He is very happy and well fed with meal worms and small garden snails. I know this is a very new tank but i hope he will be ok. I love his personallity, Puff Daddy is a great fish. He lives with anemone, two maroon clowns, a large cleaner shrimp, camel shrimp, peppermint shrimp, red head goby, coral beauty, blue damsel, and a lawn mower blenny. Several turbo med. snails and a few large red legged crabs, and a mushroom of some kind.
Its only been a few monthes, but so far its very good in there. But he wont eat anything dried, sometimes frozen, loves meal worms.
