As a side note, if you cut some holes in the line it stimulates flow in the back chamber and any heater you are hiding back there becomes much more effective. The trade-off is that you get reduced flow which for me led to some algae build up until I started dosing Flourish Excel.
After a few more days of observation, I am not so sure it's too much flow for him after all.

Did you know there is a flow adjustment knob on the pump itself? I have mine turned to the lowest setting, with the output pointed towards the surface. The betta does rest against the overflow grate, but he easily swims off when he wants. I've noticed his activity increases once the light goes out, so I'm starting to think that he may just be acclimating to the tank and light intensity, more-so than being bothered by the flow. Though, it could be a combination of all 3 things...
