I want to get a vittatus or forksahlii atf and need to bump up the current in my tank with power heads. My question is how dangerous is it for the rays tails? I am worried a ray will back its tail right into the out flow of the power head into the propeller and destroy its tail? I don't want to put my rays into danger so if its a real possibility then I wont do it or will have to come up with a new idea. Any experiences with rays tails and powerheads? Good or bad idea?
