I have a 4in Peruvian s.Rohm in a 35gl tank and I have a 660R 170gph marine land power head almost at the center of the tank. The currant goes across the tank then goes down and then there another current at the bottom but looks kinda strong. Is that unhealthy for my piranha?? If so what should I do??
