The hand that feeds

I have a couple bully fish in my large tank and I've been undecided about what to do with them. Tonight as I was cleaning the tank, this guy, and ice blue zebra, bit me. And not just nipped but actually attacked my hand as I attempted to clean the gravel around his territory, which equates to about half of the tank. It didn't hurt but it ticked me off. Back to the pet store with you! Time to get some fish that will appreciate me.
