puffy or irritated zoa?

[clownfishdaddy]

i have had these zoas and palys in my tank for about a month now and they are growing absolutely great the green ones seem like there going to takeover in the future but i will address that when it comes but i will have always one zoa or paly look seems to be swollen im not sure if this is just a natural part of them or if they have too much or too little of something any idea or suggestions its the one that seems inside out with its tentacles not showing much

Green implosion paly. They are fine.

Yes. They will take over. Most of us regard them as a nuisance.

It’s called “umbrella syndrome”… look it up. No one really knows why it happens, but it does. Most folks believe it’s related to having too much light. And yes, those little palys will go crazy lol downside of those is they don’t form a “mat” like zoas… they’re individual polyps. They can release and get blown to other areas of your tank where they can attach to something else… just keep an eye on them, move any that let go back to where you want them. But beautiful nonetheless
