I just have to vent: I am sick of my RBTA moving all over the place and getting himself caught in the return of powerheads. I feel like every day I'm coming home from work and checking to see if it's still alive!
We have a rock pillar surrounded by sand that we keep our BTAs on. Nothing but anemones go on that pillar. They're not fans of crawling across the sand. They stay put and no worrying!
