It's really not bad. Just don't over feed. Once a day tops and not fistfuls when you do. They are good fish and interesting to watch.
There are fish out there like a green terror, red devil. Red terror. All good looking fish. Mean but neat. Get about 10" ish. Flower horn if you want a central American cichlid or frontrosia? If you want African. 7 lines frontrosia's look better than 6 lines. In my opinion.
