My anemone has been unhappy for some time. I assumed it was because my 2 clowns were stressing it. However I have moved the rock holding the anemone to a basket and it is still not opening up. My water parameters are ok, other than my salt is a bit low, which I'm addressing. Any thoughts? I have a 75 gallon tank (8 yrs running) with LR, the clowns, coral beauty, yellow tang and cleaner shrimp.
