I have a very large BTA that I got with a pair of clowns. I was attached to a rock when i got it but now it has move onto the bacl glass. I have large hang on back filter that I use for flow and mechanical filtration and it is nearly wrapped around the intake. I know powerheads are bad for them just wondered if I need to be concerned about the HOB intake also. It must have moved last night and sems to be ok but just a little concerned.
