So I added dithers (silver dollars) and my umbee came out more for a few days chasing and displaying now it's back to the cave or the filter intake if he gets caught out in the open. Such an awesome fish when he's displaying. Just trying to be patient for the day I can actually see my fish regularly. Will he come around? Is it worth the wait? Is there anything else i can try? So frustrating to have an empty looking tank. Fish i speak of is specimen in my avatar.
