Water Flow Too Rough?

[saltdog]

I have two small 1/2 inch Ocellaris Clowns in a 125 with two hydor Coralia 750 powerheads. They appear to be staying at the top front left of the tank and look like they are always struggling against the current. There's plenty of places in the live rock to take refuge from the current but they wont leave the top of the tank. I shut the powerheads down and they swam around a little bit. Could I have too much flow in my tank?
