While turning off my ph's for my Picasso Clowns to acclimate, my GBTA (which has been still for a couple months) is on the move again and getting dangerously close to my overflow. He's stuck to the back glass of my tank right now and moving up. Being on a smooth surface, can I peel his foot away safely or should I just mount a PH at him? I want to physically move him to a new location I have built where he is surrounded in LR and rubble so maybe he'll stay put.
