From my experience its usually the Females that get more aggresive. Maybe you should try feeding in their enclousure. I've noticed that it makes a big differance in the "taming" process in males when you feed in the tubs. No explanation, i couldn't tell you why. Also, i would higher the temps to about 93-95 if they are not already. The higher heat for some reason keeps the animals more docile in short time frames. 2-3 days tops.
