I have a 60 gallon mbuna tank set up. I have 10 juveniles, including 2 yellow labs. I noticed the 2 labs yesterday circling eachother really fast and them "fighting". Today, one of the yellow labs is not allowed out f the rocks, or else it gets attacked by the other yellow lab. What should I do? Anything? Or just let them settle who is boss? Will the loser lab ever be allowed out again without being attacked?
