I just stocked my pond today with LMB I got from the KDFW and they were some small dudes, about 1/2 inch or so.

I put them in and watched them for a while and water bugs would chase them and every now and then catch one and swim around while carry the little bass on it's back. The bug is a common water bug I've seen them alot I've even had them in my pool from time to time. They are the ones that swim with 2 legs on either side and if you can catch one they flip around like crazy

Does anyone know what kind of bug this is and do they normally prey on small fish?
