They've quit lip locking. Now the bigger chases the smaller one around the tank, the bigger one's acting a little different from normal. I have 2 stumps, he goes from one to the other, and then chases the little one around. Both fish have brown eyes. I don't see any digging going on yet.
I'm gonna give it a few more days before I separate them. Or put them back in the big tank.
They were both together in a much larger tank, and I just put em in this 125 because of a crazy Zonatus. They did some flaring in the big tank occassionally, but there was so much traffic in there that other fish would get between them when they started circling or flaring.
They quit circling each other in the 125, too--when they quit fighting...yesterday.
