Similar situation here. I have 6 Multies in a 75g with 7 juvie Comps. Large shell bed on the far right side of the tank, smaller shell bed on the far left and extensive wall of rocks in between.
I added these Multies to the tank about 3 weeks ago. First day or two, they all hovered around the large shell bed. Then they split off one by one to the point where now they have re-established themselves into 4 distinct and separate territories all over the tank. Only one fish remains full time at the large shell bed, another has taken the smaller shell bed, another has excavated a cave under a rock (single fish), a pair has dug itself a cave under another rock, and the last one is content to make the rounds to each of the 4 territories with none he can call his own. Each territory is defended against any Comps who think they can get too close - really funny to see a Multie body slam a Comp that's 3 times his size. The Comps don't care and never strike back. In fact, I think those Multies have really gained their respect. Really cool how this tank evolved in a short time with this mixture of fish. Not what I was expecting though. I thought the Multies would stay as a group in the large shell bed. But hey, it turns out to be much more interesting this way, IMO :thumb: I too am curious what others will say about this "breaking off" issue. Is it normal?
