Valentini Puffer Fish

[DSlater]

Hey all - I'm looking for some advice. I picked up a Valentini Puffer fish last weekend for our 220 gal tank that only has 6 massive turbo snails, 25 hermits and a Yellow Headed Sleeper Goby. The occupants in our nano tank will be moved over in the fall. I have a Tuxedo Urchin, more snails & hermits, a pair of Occelaris Clownfish, a Yellow Clown Goby and a Starry Blenny (that was just put in there to help get rid of the hair algae - he was bot for the big tank). I was told that 9 out of 10 Valentini's are fine but this one is already nipping at my snails in the evening. I phoned the lfs and they said to make sure the fish was well fed and it should be fine... has anyone had experience with these fish? any thoughts? Much appreciated. Cheers!
