How to help dying sickly Zoanthids?

[eamike261]

All of my params are fine.

3 days ago, I picked up about 10 frags of different zoas from a fellow reefer that had a tank crash a month or two ago due to an additive he used for a nuisance algae. Since then they have been in his "emergency" tank with a few other corals that survived the ordeal.

4 of the zoa frags looked excellent in his tank and have since opened up fully happy in my tank.

2 of the frags were not open in his tank and still not open in mine.

3 of the frags were very shrunken, semi-open, lacking full color, and clearly some of the skirts have melted away. They look the same in my tank.

What can I do to best help the 5 sick frags recover or grew new polyps? Is lower flow better? Lower lighting? Should I target feed them like I do with my other zoas?

Thanks for any info.

It’s been 3 days. In my experience, corals tend to take a little longer to adjust to new water, lights, flow. I’d give them a few more days and see if they open. In the meantime, I wouldn’t put them in the highest light intensity or highest flow.

Agreed.

Lower light and lower flow. See how they do after that

Give them ideal params and just give them time to recover

Just to clarify, all the ones that should be are open are actually open. The ones that are closed weren't open in the first place so I certainly didn't expect them to be open within the first week. My goal is to bring them back to life.

The first picture, for example, are fully open. Those are Utter Chaos but the skirts have melted away and the color has all faded. Have you had any experience bringing dying zoas back? Any estimate/idea of how long it can take to see any change in the condition?

These aren't just pis$ed off zoas, they're actually in bad shape :/

Do you recommend feeding them or would that exacerbate the condition?

my utters did the same thing. I fixed it by upping water changes and running chemiclean. they came back in like 3-4 weeks

Okay thanks it's nice to have a timeframe to watch out for so I can gauge how they're progressing
