small green button polyps having Iissues

[LukeMoss]

Id also like to ask a favour from you lovely bunch please can you help??! I'm worried, like in my introduction I said I have some small green button polyps and they believe they have excreted but some of them have remained closed with there excrement still attached but I'm worrying because it isn't going :/ I have the coral half way up the aquarium with lots of lighting. They was fine before they excreted I've attached the best picture possible sorry for the quality. Thanks in advance.

I can't see anything coming out of them, if they are new to the tank give them a few more days - I have had zoa colonies take days for all of them to open. If they were going down hill they would appear to be melting away.

Any of your params off? What's your lighting?

 

[LukeMoss]

It's just like they have a black head but they've only closed since they've excreted, maybe they aren't ready to come out yet I only bought them last weekend... All my levels are good and I'm using the stock lighting as well as another blue LED strip that I was told to buy... All the other are doing fantastic!

What stock lighting on what tank?

IMO those are zoa's and not green button polyps. I have green button polyps and they dont look like that.

They are zoos. Lighting or params may be the problem.
