Need advice on zoas

[Patrick]

This zoa was getting smaller so I dosed aquavitro fuel. The polyps became much smaller but the mat seems to pop up more polyps. Is this normal?

Its hard to tell but i hope they open. Ive never truly maintained any water readings but it seemed like they enjoy slightly lazy water maintenance.

Sometime, something irritated it, It will not open. Worst case slowly die off.

Btw how long has that piece of zoa been in your tank?

[Patrick]

I have this piece of Zoa for a month or so. Initially polyps opened fully forming a ball but I see that it's slowly getting smaller. So I dosed aquavitro fuel and can see the mat started to pop out new polyps which I think is a good thing, but all the polyps which used to be big became smaller. I can hardly keep zoas except palys. Hence, hold off buying nice zoas for now.

Zoas actually require a decent amount of light. I notice many lfs tend to put it under blue light. Its nice an pops but in the long term they will not survive because there is insufficient light.

Yeah bro I remembered something now. Check for nudibranch. I remembered my colony of zoas were behaving like yours until i took a closer look and found damn nudibranches. They camouflage really well. I dipped mine in ice cold plain freshwater and saw the nudibranches fall off and there were lots of them. They must have laid eggs and i bought yellow wrasse to finish the rest of them and the problem never came back.

It’s best to use coral dip like Coral rx for zoas. Other then nudi there maybe spiders as well. HTH.

As what I saw on youtube, there is this marine distributor overseas that only sell softies greatly advise on using freshwater. As zoas will close their polyps so it wont harm the zoas. Anything that are attached to them will slowly die out.

freshwater dip will hurt the coral but a cheap way of removing surface pest
