Clownfish freak out

[JPergamo]

Anyone have any idea why one of my 2 perculas freaks out when I use my mag float? Even when I use it on the other side of the tank?

Maybe they were abused as children :)
Mine used to as well. I left it on the wall for a few days so they would get used to it and now they don't mind it.

They are defending their territory.

Mine did the same.. How I gotten mine to stop was to slowly move it every other day slowly.. Now clowny is fine with my need to always wipe my tank..
