Might be a coincidence, but so far the yellow tang is avoiding the back corner with the parrotfish picture. He’s acting more normal, grazing the rock, instead of fighting his reflection endlessly. At least a temporary success!
I may have missed a few entries so my apologies for asking the question. I thought I read earlier that there was a yellow tang missing?
With regards to the page with the fish. You could do a quick test and remove it, see how it behaves for an hour or two, then put it back up :)
