Zoa Help, Whats going on with these??

[aray]

Need some help trying to figure out what is wrong. I will test the tank parameters later tonight, but I don't think there is any issue there as all other zoas and corals are doing great. The tank is a couple years old, and the zoas have been on the same frag rack for a few months. I tried a dip 2 days ago, it hasn't seemed to help. Any Ideas?

NOTE: It kinda looks like some of the lashes are half gone on some of them.

Looks like they are melting. Not sure on the cause. Seen many zoas over the years up and melt while all others were doing great.

Are they getting enough flow? Most melting zoas I have had didn't get enough flow for that type of polyp.

Ill give that a try, and more them to a higher flow area

Have you recently moved them any on frag rack ? I try to minimize movement especially on my zoa racks , but Double check late when lights go out for Zoa eating [emoji222]nudibranch.

I only moved them when they start to take the turn, put them in a higher flow area. I will take a look for zoa eating nudibranch. Thanks!
