Spotted Green Puffer, Tetraodon nigroviridis

These guys are my personal favorite.  I have had one now for two years and he's getting big.  I must say from what I have seen, they are one of the smartest fish and are friendly to humans.  They do get nippy and aggressive at times.  They can be placed in a community tank with other fish, but keep a close watch and feed them well.  These puffers are always hungry.  I find if they are feed them three times a day in smaller amounts that they nip less.  Their nipping also depends on the size of the tank and the amount of swimming space that they have.

Spotted Green Pufferfish are very entertaining to watch, especially their swimming patterns.  They will live a long time if taken care of properly.  From my experience, this type of puffer is very sensitive, so if you are a beginner, I suggest you start with the hardier dwarf puffer.  Spotted Green Pufferfish eat frozen then thawed bloodworms, ghost shrimp and pond snails . The snails keep their beak from growing too large.  These puffers are a definite brackish water fish.  When they get older, they can be introduced slowly into a fully saltwater environment.  In saltwater, they will do better and their colors are vibrant.
