It looks like zoa spiders to me. I hate them.

 

You can be lucky and hope you got one. If not, you should investigate any other zoa/paly colonies that are acting strage to you.

If they are only on zoas since zoa spiders are host specific they definitely are the ZOA spiders, best destruction method is simply physically removing them since they often use the actual zoanthids mucous as protection for eggs and offspring, keep up killing adults and it should end after a while. Some worms will kill them but you likely won't have the right worms in your tank. Even predatory flatworms can sometimes be friends.

Also the weakening of the zoas from the spiders is probably why they are being grown over by cyanobacteria as you said in another thread. As they die cuc finished carcasses most likely.

+1. They survived a bayer dip because I had a spider LIVING INSIDE a zoa. I only realized I had a zoa spider when I saw it crawling out of the zoa's mouth and trying to invade a new one.

 

I'm not sure they're egg laying types. I thought they just give birth to more zoa spiders out of the parent's mouth.........

all sea spiders lay eggs, but there are several other developmental strategies after hatching, but they have the eggs coming from their legs, kinda creepy lol

This is the quote I like the best...

 

"Leave the coral in your quarantine system for an additional 3 months before moving back to your aquarium"

 

I am pretty sure NOBODY in the trade is doing this! Sounds like these might be harder to get rid of than nudis, but perhaps much less common.

that's why its actually better just to stick to a strict kill at sight policy. No breeders no new ones, no more invasion.

So I been thinking about these spiders and they seem hella hard to get to them gone.kinda just saying screw it zoas are gone sucks cuz have about ten diffrent kinds that are nice nice already and was what my tank was gonna focus on but whatever.so what I'm wondering will they get my other corals or will the die when the demolish my zoas as they seem to be doing to some but some seem untouched

I also have been looking in tank a hell of a lot and I haven't seen one in tank just when I dipped

Nd the zoas I dipped two kinds on same rock are only ones they seem to be getting no others just my garrila nippple and eagle eyes so far but there like all the way gone and there were over a hundred zoas on that one rock

To my knowledge they are obligated to eat zoanthids. But there are many species of sea spider, some aren't so host dependent as others, the less host specific species are definitely a worst case scenario as that will mean they can feast on a greater variety of polyps. Sorry what's been happening to your zoas, did you say the dipping helped? If that did help that would be quite rare, since quite a few of the really bad ones protect themselves by living inside the zoanthid in early life stages. They have so little information made about them that it's frustrating.

oh, sorry to be all grim right now, but I don't think any of your badly infested zoas can even make it, no matter how good of treatment you try. Let me explain, even though you are killing adults on sight, assuming my guess is correct this is a very prolific species of sea spider, each adult probably is laying dozens apon dozens of eggs each with parasitic offspring. It only in that case would take a few females to cause this nightmare. When the eggs are hatching the larvae are burrowing in the zoas tissue and feeding on the ZOA, one individual spider baby isn't too dangerous but since there is/ could be dozens their destruction is much greater. Since they are living in the tissues themselves they are protected from any medicines the ZOA will likely die before the spider if you really go all out with the medicines. There will be more, you might have to just kill the visibly infected zoas ( they are doomed anyways), and quarantine like mad. I'm sorry, but that is what I am seeing as the only viable solution.

Second opinions are nice though

Ya think tanks being changed to sps and lps only and letting the zoas just go as they do. My sps are getting big and growing great anyway I guess

you might be able to salvage a few of the zoas, just first look for visible sickness.
