![]() Make sure you have no sundial snails in the vicinity. They love zoas. Make sure you have adequate water flow to take away debris. I blow them off occassionally with a turkey baster. Have you added any fish or critters that can be crawling on them and annoying them? They don't like being disturbed on a regular basis. Sometimes our favorite zoas just melt away without any apparent reason. Pathogens, bacteria, Chemical warfare, etc.

![]() Deep water zoas are somewhat more finiky than your average zoa. Something at night might be bugging them ( i.e. peppermint shrimp, cleaner shrimp, sundial snail, zoa eating nudi's, unicid worms etc etc. ). Some deep water zoas like very little light and some like more light. Also alot of zoas melt after being fragged. I have lost several of my favorite zoa colonies after fragging them. Also when you frag corals they try to rebuild/repair themselves so they use up more nutrients. So there may be a drop in nutrient levels for a couple days or that particular corals imune system is very weak.
Try adding a drop of iodine once in a while as it seems to help with my zoas and mushrooms etc. Some fish will aquire a taste for zoas later on too. Just when you think they are safe they eat your favorite coral. ![]() Hope you find out what's wrong. Cheers

![]() In my experience it is generally not wise to frag zoas that are in a state of distress, unless you see a visible bacteria,etc. and you are trying to save the colony. Any time you frag, you create stress on the coral to various degrees. Zoas are hearty corals, but with any coral it is a crapshoot as to your success. That being said, I have fragged many colonies with very limited losses. Polyps that grow individually in the rock are a lower risk. Polyps that grow in a common mat and have to be cut away and/or scraped off the rock are a much higher risk.
