are monos known to be agressive tward everything?...idk if i just have a dick-head mono or what...it has killed a bgk, beat another bgk, eatten 2 silver aros, attacks my larger silver aro, beats up my lima...this thing is a beast...my orino picks alittle at a fish, the mono sees that happening then unleashes the fury on the other fish...i don't get it...it is well fed, but a prick...is this normal?
