I have an established reef and think that purchasing a valentini puffer would be okay. Heard they will nip at corals though as I said I don't believe he will do enough damage that's noticeable or kill colonies. I noticed that they were at my LFS awhile back. However now I can't find him on the page. I Aldo looked him up and it appears that the price has raised quite a bit from when I first saw them. Are you still able to find them at your LFS? Are they more pricey-er?
