I bought my zoa along with my other corals a month ago. My other 2 seem fine but my zoa has been getting more shy and not opening up as much lately. I was wondering if it was because of my light (Nicrew Hyperreef 30w)


My tank is 18x19x18in tall
I also just set up the tank a few months ago. Is my high KH the problem or could it be other factors?

Your numbers look fine to me and your light is fine as well. I would check for pests as there are a few that can be problematic for zoas.

That stated, sometimes they just get moody. If they’ve only been like this for a day or two I wouldn’t necessarily worry about it, but if they’ve stayed like this for a week or more then there likely is something causing them to be irritated/closed up.

Edit: I took a closer look at your pictures and it looks like they are stretching for light. You might want to turn up your light a little bit.

someone correct me if I'm wrong but to me it looks like the zoa's are reaching up

Only a few polyps of the zoa have been shy for about 2 weeks. I also don’t have a sunrise and sunset feature in my light so it just clicks on. Could that be shocking my coral?

No that’s really not an issue.

Give it some time all the other corals in the tank look good don't change stuff for one coral if everything else looks happy.
