Figured I would post this in this section. First article I have seen showing cichlids playing. Though I do recall us having several members that claimed their discus liked to play in the water from the hose during water changes.
In any case have a read of the whole article.

How to test if this was playing
The researchers wanted to make sure the fish were truly playing. After all, they reasoned, the fish might just be aggressors letting off some steam, or hungry guys angry at not having enough food — or even lonely guys frustrated by not having a mate.
Male cichlids vibrate their whole bodies when looking for a mate, Burghardt says. But these fish were not doing that. Their thermometer-bashing also didn’t seem to have anything to do with being hungry. These guys did it before and after eating.
Finally, the videos showed no link between thermometer batting and aggression toward other fish. Former bullies who could sometimes see others of their species in a neighboring tank might race at the glass wall, as if they were trying to attack. But even when they could see these other cichlids, the sequestered males still played with their tank’s thermometer.
In the end, what the fish were doing looked a lot like Burghardt’s definition of play. He defines that as repeated behavior that has little to do with finding food, finding a mate or fighting off predators. Animals do it when they’re relaxed or bored, he says.
