Zoa starting to invert it's shape. Thoughts?

[Jib]

Over the past 10 days, one of my new Zoas (put in tank on 12/6) has started to invert it shape. It had the classic cup shape once it settled it. It slowing been inverting it's shape now though.

Any thoughts what could be causing this? Other Zoa's in the tank seem happy enough...although it should be noted I believe they are reaching for some light. The Gobstopper (Red one in 2nd pic) is also opened up more broadly, and less cup shaped then before. I attached a picture of my lighting schedule, if anyone has thoughts to the intensity I'm happy to listen. It's a modified Saxby schedule. I decreased the overall intensity by 40% of original, then halved the white light intensity again for my desired look. Tank is a IM 14G Peninsula.

Parameters:
Temp: 78
Salinity: 1.025
NO3: 12
ALK: 9.6
Ca: 415
Mg: 1215
PO4: .03

Thanks in advance for any thoughts.

They are hungry!

For more light or actual food? I forgot to mention I do have BRS reef chili which I did broadcast feed yesterday. I hadn't been feeding it before that though due to a dino outbreak I was getting under control.

I’m sorry. I meant for food! I have the same zoa’s that you pictured and when they were like that I just fed them. It could also because you already fed them too. That’s just my small experience but I’m willing to bet someone with a little more knowledge can chime in. But with that being said they DO look healthy.

They may be hungry or they may be getting ready to poop.

Google zoa umbrella syndrome.

It started before I fed them yesterday. The food didn't seem to impact their appearance either way.

They may be hungry or they may be getting ready to poop.

When I've seen them poop they didn't change in appearance at all. Maybe something is different this time. I'll keep an eye out.

Whoa, so this leaves me with more questions than answers : ). But somehelpful info to think about. Thank you for providing that terminology.

Now that I think about it, a lot of my zoa’s look like that when they are pooping. Lol
