Hey folks, I currently have an 80gallon setup with 4 Black Ghost Knives. They've been leaving each other alone for the most part, and socially acceptable when around one another. Until recently that is. One of the Knives just broke 7inches and has started to pretty aggressively chase the others around. I have plenty of hiding spots, but is the tank too small to keep the dream? Do you all think it will mellow out, or do I need to cut back on my Knives(no pun intended)? Thanks.
