Well I had a Yuma that was well placed. It soon became very, very large and just recently started to sting my blue mili colony. I tried to move the darn thing but it soon ripped to shreds. Any tips for the future for moving these things if they get too big? I tried the power head method and moving the SPS was not an option. I also have an infestation of mushrooms that need to be groomed. Any tips for these as well? I just ripped these apart but I didn't feel so guilty as I did with the Yuma.
