I have two midas in my 400 gallon tank with a bunch of other cichlids, and we noticed last week they were acting very aggressive towards everybody that swam around a certain area but not each other. They seemed to be protecting that area, but I didn't see any eggs or anything like that. Wondering if it's possible they are pairing up? They aren't doing it now, but I was curious why they were doing it for a few days last week. It was very noticeable. The smaller one cleared out all the gravel from that area right to the bottom too.
