Hello everyone! I am noticing quite a bit of flashing from my Midas blenny after recently adding a new purple tang. I noticed a little white and stringy poo coming from the purple tang. They are both eating good. I don’t see any ich on them. I am trying to put all these signs together and see what I can do to treat them. There’s no way I’ll ever catch the blenny without tearing the rock structure down which really cost too much to tear apart sadly It isn’t stable enough to pull out. Are there any treatments out there that I can use in a display tank? Prazi pro or general cure? I would greatly appreciate any and all advice. Thank you for your time
