zoas melt away , why?

[STHILL]

What causes zoas to just melt away? This has not happened to me in a while but all my zoas would just melt away after a few months

What would cause this?

I've found that in my sps tank they will melt but in my fish lps they do fine. Came to the conclusion that it was too much flow, light and lack of nutrients.

I'm gonna say lack of nutrients. Every time I see a thread about zoas melting away, they are put into a very "clean" tank. I'm starting to beloved that zoas like dirtier water and do much better in a LPS/softy tank versus a sps dominant tank.

Try moving them to the bottom or in the shade for awhile. Could be too much light aswell.

i noticed my zoas melt twice a year around this time when seasons change.

I have a "carpet" of zoas on the bottom of my SPS dominated tank so the nutrient theory might not be entirely correct.

Check your colonys around for little nudibranches, this is what happen to me, i got two little frags from one member here and got my tank infected. The nudis I got are about 1/8" long and has nice green and pink/orange colors I had to remove all zoas from my tank.

i just had DD red people eaters colony just melt away for no reason while my tank has a lot of other zoas that look great...not to sure why, actually hoping they come back somehow so i left the rock in.

I have the same issue I cant keep zoas for some reason ether or most softys ether.

I read alkalinty swings could lead to zoa melt. So for an sps tank w zoas who doses (manually) this could lead to it. I've at least convicned myself thats the problem whenever zoas melt.
