Light brownish algae growing over zoas

I'm not sure exactly why zoas do this but I've noticed this happens to me when they are dying. I think they start to melt, close up, algae grows on them (maybe high nutrients there), and then they eventually disappear. It is very hard to bring them back from this but I've done it before. I brushed off the algae with a very soft paint brush, dipped in revive, and then would monitor and repeat when necessary. Maybe you could try Furan or iodine dips. Expect high mortality.

Hey i tried moving them to a higher flow area, possibly a little less light but they are mostly opening back up and the algae is definitely down.

Most are open, middle part of colony was closed when I got them

give them some time; zoas are a fickle coral, can take weeks sometime to get accustomed to new tanks and open up. Do you check iodine levels? From what I understand they respond to iodine supplementation, if the levels are low in your tank.

Radioactive dragon eyes tend to be among the more fussy zoas in my experience and all or nothing. They prefer larger tanks with stable pH and alk. I see them a lot in really big SPS tanks where they thrive but I've had trouble with them in my smaller tanks that are already paly / zoa dominated.

Dragon eyes should never stretch towards light and they do like a bit more flow than other zoas. That's how you can tell if there's not enough light. Yours look really healthy with fat skirts.
