Do males become aggressive as they get closer to sexual maturity?

I don't think so. My boys are more mellow and laid back than my females. I have 2 girls that can be nasty just from opening their tubs.
I say that your boys just have a strong feeding response. Do they show the same aggression while handling them out of the enclosures?(not during feeding time)

And feeding in a separate feeding bin isn't really necessarily. I would think that is what is conditioning them to be aggressive if anything. They're saying, "Hey! It's the hand that leads to food!"
