What convict cichlids do when they're bored

The pair that did this lost their territory in the big tank, which now has two breeding pairs in it. I pulled them and put them in a new tank which didn't have a substrate (intended for use as an isolation or grow-out tank.

I may get rid of the substrate in the big tank and put in pool filter sand and another less prolific cichlid.

A friend caught this female and her mate and some of those babies to take to his house, but the male finned the plastic bag and ended up damaged while I ended up with water on the floor.
