I was thinking maybe a vallentini? I have no shrimp. I have about 15 turbo snails and two mythrax crabs. Corals are zoas, acans, frogspawn, candycane, rics.
Puffers are some of my favorite fish, though I don't think they are at all reef safe.. not even "with caution"
Could you chance it? Sure. Is it really worth it? That is up to you.
Even though I love puffers I'd not chance it.. because I simply love my entire reef more.
I agree with all the above coments. I had a blue spot sharp nose and a vallentini in a reef for about a year w/ no issue until they one day decided to try a monti cap. It was all down hill from there as they realized they were living in a buffet, lol.
