Hello everyone, I'm having a bit of trouble with a toadstool leather. It appears as though it's being eaten (See Pictures). I have a long spiney urchin or a yellow tang that I believe may be the culprit. I have the leather under mod lighting (VHO), and fairly strong flow. My water parameters are: Nitrate 0, sp. grav. 1.025, cal. 380, Phos. 0, KH 11, temp. 78. I really do not want to loose this frag because it's so awesome when it's open. I also have a number of other corals (LPS, Soft, Zoanthids, Ricordia) that are not affected at all.
Please give me some ideas, because I'm thinking about buying an in-tank quarantine to keep everything else from getting to it.
