I would watch out with zoos and polyps. They should be good with lps,I have 3 puffers, the dogface type puffers will get into more corals, a porc would be good choice for some lps corals. my puff's all puff up once and a while , I have read they do it from time 2 time, just to see that they can still do it. Kinda like practice.
