I had about 6- 4" umbees in a 110g tank. Didn't think i would have any issues for a while but the alpha male killed off what i believe was another male. I know i will eventually have to move them but i really wanted to see if i could get two of them to pair off before I started separating. The alpha male keeps picking on the rest of the bunch. Are there any bichirs or whatever that i can add to distract this guy? I would love to get as much time out of this tank as possible. thanks
