Ok so my tank is a 40 breeder and I have had a coral beauty and a lawnmower blenny for around two years. It has about 35 lbs of live rock and alot of corals mostly zoas/palys, leathers and hammers. So My issue is that certain colonies of zoas are slowly being depleted. At first I was suspect of my coral beauty but have never seen him really nip at zoas consistently, I have done a lights out test. I found a few asterina stars on them and have been removing them ever since but am still unsure if they are the culprit. The main colony I am concerned about I even dipped and nothing fell off but one star.
So now I go back to the coral beauty and watch him very close yesterday and I def saw him nip the toadstool a couple times which annoy it but I dont see any real damage being done. He also nips around very close to the zoas but I just cannot tell if he is eating the zoas or whats in between. The zoas that I see are damaged have missing skirts, close up and never come back. Anyone have any advice on how I can find my zoa eater?
