At my wits end with zoa's!!!!!

[davejep]

I have been having an on going issue for a while now. Things will be chugging along great then all of a sudden I get this.
Can't for the life of me figure out what is causing this. Top picture of sunflowers, I've had that one for a couple of years and now all of a sudden this. Grrrrrrr

have you looked under a magnifying glass for pests? dipped them?

 

[Tahoe61]

Have you looked for the usual zoanthid eating suspects. Those zoanthids look like a nudibranch has been munching on them.

Also, some of the zoas are reaching for light. When they got long stalks like that, they need more light.

I had a Sundial Snail and a ZoaSpider eat my zoa colony's. Never been a fan of zoas since.

Had coloneys do stuff just like that skirt falls off almost furan 2 withh cure that just make sure you do followup dips

looks like they want more light or are infected/pest annoying them

 

[davejep]

I know the one is reaching for light. It's down on bottom of tank, not worried about that. It's the random shriveling and shrinking that is driving me crazy. Not pests, have had nudis in another tank in the past so know what to look for there. No white spots on any of them just all,of a sudden within a day they contract, head shrinks down and they wither away.

I've had zoas do the same. Dipped them in coral Rx and to my surprise countless bristle starfish fell off. After the dip and significant reduction of the bristle stars the zoas are fine. They say bristle starfish are good IMO they irritated the zoas and the zoas would melt away.
