This past Saturday I added a Toadstool leather to my tank and right away the think opened up and had full polyp extension and looked great. My Duncan coral was looking really good as well with good extension. Ever since then neither has come out at all both being fully retracted. So I thought it was due to fish traffic so I moved them both to different location.
Yesterday at lunch they were both maybe 50% extended and I thought "ok, they'll be fully extended when I get home tonight". NOPE. Ever since they have not been extended one bit.
Here are my questions:
Should I worry? Are they still adjusting to the new locations? Do I have a fish bothering them (potentially the six-line wrasse or the Pacific Blue Tang) as they always seem to be near the corals? Should I cover the corals in a strawberry type basket to keep the fish away but still allow for flow?
I've never owned these types of corals before so I'm not sure what to expect. All my other corals look great and show no signs of stress. Montis are all growing and looking great, crown leather is full extension, zoas are all open and happy, mushroom is open and looking good. I just can't explain it. Seems like the corals with long tentacles might just not work in my tank????
Your fish are not going to bother your corals. They are probably just adjusting to your system. This can take a couple of weeks sometimes. Differences in ph, salinity, lighting etc. are all reasons for it. Leave them alone, let them be, and see how they do. they should be fine. Patience Grasshopper....
