I recently lost my lawnmower blenny and moved my pair of Ocellaris clowns to a new setup. I want to add a new fish to my 30 gallon tank and came across someone saying that the Valentini puffer would be okay around the coral in my tank. I just moved all the hammers to the new setup as well and will be transitioning my tank to be dominated by sps. I do have a Zoa rock as well as a toadstool leather and gorgonians. On top of whether the puffer would be okay with those corals, I need to know if I would have trouble with the puffer eating my colony of sexy shrimp. I currently have 10 of them cruising around my rock flowers and Zoas. I was recommended an alternative fish to add which would be a smaller species from the from the genus Genicanthus.
