Hey fellas, was curious as to why this Zoa along with a couple of others are acting like this. BTW my parameters are within range. TIA!!!

Sometimes zoas just do this. I call it "mushrooming" haha if it continues to do this I would just move it to lower light.

Looks like you have it way on the bottom. If it continues to do this move it under a ledge. What type zoa or paly is this?

Before and after. Like when the lights go up at the bar and you really see what you were talking to.

When the polyps look like someone has pulled the skirts down like the one in your picture is called "Umbrella Syndrome", its known to happen to People Eaters palys, like blue agaves, red people eaters, etc. it seems to be a sign of stress or discomfort due to lighting . Try moving them to a more shaded area in your tank and see if that works. it looks like is going to recover though. The polyp looks healthy just with a weird umbrella shape.

There must be more to it, because I have seen my polyps do it during feedings as well, otherwise it doesn't happen. Only with broadcast feed though Some of mine did it when I tried out that sample of coral frenzy.

I don't target feed. But like you said, there's more to it.

I think its more to do with lighting... I agree to shade it a bit to see if that helps. I have a GOW frag that the center polyp has the umbrella shape, but all others around it that are new polyps don't have it. I think it was light shocked initially for whatever reason. **Its been that way for at least 8 months now and hasn't changed shape at all.

I have also noticed the Agaves prone to doing that which I think is also to do with the high lighting in our tanks.

I look at it like its the opposite of when a polyp "reaches" for light... elongated stocks etc.

Chad- I'd be interested to see a before and after pics when you broadcast feed, with the polyp going back to normal.
