So I was talking to another BAR member looking to trade some zoas and I asked if he liked any of my all yellow zoas that i have had for about 5-6 months. He said that that zoas had gone melty on him a couple times so out of curiosity I inspected mine further and realized they were slowly dissapearing from comparing past pics. What I see is that they close mostly, expell their zooxanthellae and then melt away. So I began dipping in Revive but that only seems to slow the process slightly. Kinda frustrating cause 90% of my zoas tank thrives the other 10% seems to slowly dissapear. Is there anything i can do?
