Here they are everything has been good, I have been trying to increase nitrates and phosphates to battle Dinos and the rastas haven’t changed since the increase. Previously they were showing more stalk and not a shriveled.What are your params?
They look open...
Do you monitor your Ph? How long have you had those rastas? They look open to me as well.Here they are everything has been good, I have been trying to increase nitrates and phosphates to battle Dinos and the rastas haven’t changed since the increase.

I do, a few days ago I was low around 7.8. They are my oldest around four months old.Do you monitor your Ph? How long have you had those rastas? They look open to me as well.
I run a CO2 scrubber as I'm in a basement with decreased oxygen availability. Your Ph will be at its lowest early in the mornings when lights are off. This would be a good time to assess your Ph levels to ensure they are not falling bellow 7.8. Also, zoanthids can be "finiky" at times so if all your other corals appear normal then I would wait and see if they do not go back to "normal" as well.I do, a few days ago I was low around 7.8.

This all happened after my moved them slightly a few months back(literally within a 2-3 inch radius from where they were before). I was thinking it may be too much light as well. Just strange the other ones seem to be fine.Did you make any changes to your lighting or light schedule recently? I've found that lower PAR with longer photo periods seems to make bigger zoa polyps. Higher PAR, and higher flow to an extent, can make them shrink.
I normally do five gallons every Sunday but I am currently battling Dinos so I have not done a water change in almost two weeks. However these rastas have been this way for over a month. My ICP results showed I was lacking in iodine so I have been dosing iodine for about two weeks now as well.A modest water change is always a good 'pick me up' for zoas, I don't see you mentioning having done one recently in the tread. While it's good practice to dose lugol's (iodine) a small water change will also replenish iodine and all the other trace elements that get used up.
