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.

are you running carbon?

How long do you have the rasta zoas?

I have a chemi pure that should be replaced, but I had a new bag of carbon in it all week after the treatment. Also, the other corals, including Zoas look GREAT!

Have had them for about two months and they had been multiplying.

i find zoas to be weird. I just added some tubs blues, some red zoas, and some miami hurricane zoas. The MH melted in a day, the reds opened once and havent opened since though i can still see the color, the blues never close.

i would look out for any pest( not saying you have them but good to keep in mind) or i would try lowering them so they can try to return to life. i would also try to do a iodine dip that always helped my corals

Do you have them up to high / or are they getting to much light? Zoos sometimes get smaller in more intense light

I had this happen until they just Vanished. Tried the exact same Zoa again and its thriving

I'd do 30% water change and keep them in lower light med flow

They are high in the tank, but were doing great up until a day or so ago.

Thanks for the advice everyone.

I will move them and see what happens.

I had just done a water change and I do a 20% weekly.


Thank you for the advice I hope moving them will help.

Hope it is not too late!
