What's with these Zoo's?

[VietNR1]

Hey All,

Can anybody help me out with these zoo's? I moved them over and they were doing ok until one day they started to just look a little crusty if that makes any sense. They stopped opening up and have been stuck the way they are in the picture. I tried a lugols dip and it hasn't done much. Any idea on what could be the problem? They are the zoo's to the right of the chalice, underneath the hair algae my tang has taken care of. I have other zoo's in the tank that are doing just fine. TIA

they might need to get used to the new spot, or maybe to much flow is right there? hard to tell why they are not opening..

Maybe try moving them to another location in your tank, and see how they do there.

I had a zoo with the same issue as yours
I did remove the hair algae by hand and move the zoo to a middle location in my tank where it gets more lighting and now is doing great.
I have 14k HQI what about you?
