Help! Rasta Zoas shrinking!

[Overlook Reef]

Hi
I have some Rasta Zoas that have been doing great right up to a week ago. They appear to be shrinking! All the other Corals in the tank are doing great, including other Zoas.
Any ideas?!?!

Temp 79
SG 1.26
Nitrate 0
Nitrite 0
Ammonia 0
Phosphate 0
Calcium 460
Alk. 10.5

I did use some aiptasis x the other day, but it was not even close to the Rastas.

move them down. they may be getting too much light. Did u acclimate them to the light in the tank?

They have been there for about two months and where doing great.

maybe a trick olf the light, but they look a bit bleached to me. duno.

Rastas have a reputation for being melters. When in doubt the first thing I usually do is a good water change and run some carbon. Don't know if it will help but it won't hurt.

Move them to a different area. Maybe they're bleaching from too much light intensity.
