This all started over the past month.
My rock with a colony of green zoas slowly got plagued by this purple skin like substance that has killed 90% of them.
Now it has spread to my red colony.

The tank has been established over a year.
Everything else is extremely healthy.
Water parameters are good.

I dipped the green colony in 70% salt water and 30% peroxide the other night, but it only killed bristle worms.

Any ideas???

I don't believe so.. it's growing really fast and the texture is like the skin of a green star polyp..

Is it some kind of sponge? Take rock out and let it sit on counter for 15 minutes-if its sponge that should slow it down if not kill it.
