Hey there-
Our Zoa looked happy and healthy for a few weeks, then BAM. Started closing up, getting dark, and grew what look like little tuffs of dandelions are growing around it (see pictures). As suggested by the store near us, we gently tugged off what looked like algae and let it sit to "cope" with the trauma of being prodded. But after a couple weeks longer, the poor thing is drab where it has opened, and a large majority of the zoa still hasn't re-opened at all. All parameters are (and have been) good. All other corals seem to be happy, including other zoas that are in the tank, bright and open.
We're new to the saltwater world (aka, I'm not sure what info to share), but our 14g BioCube includes:
Coral: zoa, favia, ricordia, duncan, frog spawn, hammer
Others: nassarius and other snails, 2 small clowns, 2 sandsifter (gobies)
Zoas in distress: to the immediate lower right of the clown
The little dandelion-puff-like bits are white, flexible, and generally shaped like a martini glass. They're seen most easily here on the right half of the zoa.
There are also very small tube-like bits that have a white, snowflake-like growth at the tip. It's hard to catch up close via cellphone camera, but you can see examples at the 11-o-clock and the 5-o-clock of the nearest polyp.
Thank you for all of your help and wisdom!
