Question on my zoa's!

[Tyler Bullock]

I have these 4 corals in my tank. Still trying to figure out the aquascape. I have had these corals for probably 5 weeks. About a week ago my left one will not open hardly at all. The right one is growing more polyps . Should I just move the left one around my tank to see if it will open up? Not sure what is going on.

Tank looks extremely new. What are your parameters

Looks like a aiptasia on the backside of the closed up frag. That might be one issue.
Also, I really can't be sure, but I'm looking at that little green frilly thing on the front polyp.
Either just part of the skirt sticking out or it's a nudibranch. I really can't tell. ( old eyes.lol)

Add some superglue over that aptasia to stop it from spreading. Ive tried aptasia x but it really doesnt work that well as the superglue.

And what lighting do you have? Its it strong enough for those corals?

Here are the perameters

Temp = 80
PH = 81
Ammonia = 0
Nitrite = 0
Nitrate = 0
Salinity = 1.026

Tank has been running for almost 2 months. Stock lights from the fluval evo 13.5. The lights are good for zoa's. I took the coral out and inspected it pretty well. Only thing that was on it was a few pods. There is a small bit of rock on the frag.

The aptasia are nearly impossible to see if you disturb the drag. They shrink to almost nothing. You have to apply the aptasia x or super glue in situ. I’d encourage you to knock it out now before it spreads.

I have cleaned off the aptasia and put super glue on it as well. I will post another picture, when I get home from work, if they have still not opened. I moved them back a little towards the rock.
