These puffers grow quite large and at a rapid rate. When they feel there is not enough adequate room, bothered by other fish, or improperly fed they simply put their teeth to good use. I've maintained these puffers in the past prob. close to the 10yr mark if not more and at full growth...they do fine with fast moving and aggressive tank mates, not passive dither fish you see in most "standard" aquariums.
I have a green spotted puffer. Would a percula clown be Ok with it?
