I’ve got a small colony of micro zoas that I’ve had for about a month and a half. Tank is 2 months old, they were my first coral.
They were open and seemed to be having no issues up until about a week ago. Now they are closed and several of the polyps are “reaching “. I’ve moved them slightly a few times to rearrange things but never more than a few inches. If anything they’re getting more light than they were before.
Water parameters have been stable and no other corals have shown any signs of issue. Other zoas are still opening.
Only potential issue is I’ve found two nudibranchs in the last couple of weeks. Both were on the glass away from the zoas. I’ve inspected all of my frags and can’t find any evidence of others.
Just sort of at a loss on what the issue is and what steps I should take, if any.
Previously open
Current state
