A Question And An I.d

[mark7616]

Right im a little confused about my polyps they seem to of dissapeared can anyone tell me what has happened???

They went from this.

To this

Also whats this red stuff growing I have a fair amount of it but have no clue as to what it is?

Well that other stuff is a plating calcaerous algae, I have some of it too . Always good to have pretty algaes like that.

As for the Zoas, predatory nudibranchs/fish/crabs/fireworms/sundial snails come to mind...

All I have noticed is I did have a hermit a while ago living in the middle of all the polyps if you took it out it would go straight back there.

Do you have a QT tank? It may be a good idea to place the rock with the zoas in there and monitor it at night.

Zoanthids have all sorts of predators that can easily make their way into a tank. I'm sure SkiFletch will tell you that even large populations can remain undetectable for a long time.

Ive had them 6 months and this has only happend in the last 2 weeks I dont really know what to do about it I dont hae a QT tank.

Use a red flash light or a regular light with red film over the lens and watch the zoas at night, look for snails, crabs or tiny bugs that you didnt put in the tank.
