Blue spot puffer - Reef safe ?

[maron6977]

Well, I'm gonna do a tank swap soon. At the LFS & saw a blue spot puffer, I'm a sucker for puffers. They said it was reef safe with caution. Well been a couple days & it's coming out more & getting comfortable . Noticed this morning he's biting sps , especially my valida (that's finally coming around) . Keep throwing in food with turkey baster. The flow from it or the swarm of other fish freak him out & hides . 5 min. later he's out nipping at things again .
Anyone have input good or bad ? Is it just a phase if I keep trying to spot feed him ?
If he doesn't stop , probably won't transfer to new tank.
