+1I use those Mag Float cleaners to clean the inside walls of my tank. I haven't noticed any reaction from the rays other than moving away from the cleaners. But they move away from anything foreing.
Same here Jason,absolutely no reaction what so ever other than what you have pointed out. I keep 6 ray species all of which are isolated from one another and I haven't witnessed anything out of the ordinary over a 30 year period.I use those Mag Float cleaners to clean the inside walls of my tank.

Good info zoodiver.Magnetic barriers are proven effective against sharks, and some rays. It seems to impact ORV elasmobranchs much more than the benthic counterparts. It takes a much stronger field to distrupt a benthic animal.
