Ok so I started with 1 rbta about a year ago now I have 8. This is getting crazy. I have one big one on the glass that doesn't move 6 on a huge rock and now 2 on a rock on the other side of the tank. The ones on the huge rock don't really move but the now 2 on the smaller rock are moving into my other corals space. How can I get them off without removing my rocks? I have a extra mp10 I can try to flow them off the rock but if they move to my other big rock it might be impossible then to remove them. Is it possible to cut the rock under their foot? Lights just came on I'll snap some pics
