What fish can puffer fish live with?

Answer 1

Due to the unusual salt requirements of the Green Spotted Puffer (they can be kept only very short-term in freshwater, they need high-end brackish to survive, and when full grown, most people choose to keep them in full marine conditions), and their aggression, tank mates must be chosen carefully. Green Spotted Puffers are not a shoaling fish and do not need the company of other fish to keep them happy. With careful planning and enough tank space there are a few fish that can successfully co-exist with GSPs. Mollies (though, they may become a tasty meal) can in theory, co-exist with puffers throughout their entire life. When in full marine conditions damsels, and clownfish can make excellent tankmates.

Answer 2

Puffers live mostly in the reefs of warm water oceans. They are capable of eating nearly anything that doesn't swim away. With fused tooth plates they crush sea urchins, worms, snails, and many other invertebrates. They are fairly slow, but capable of bursts of speed. (reefannie)

Answer 3

I have a clown fish and several damsels with my puffer and they do just fine.
