I don't see anything wrong with the question. He could have worded it better but it's nothing to get upset about.
I like cichla for their size, colour and shape. They are beautiful to look at. Also I love their power. They shoot effortlessly through the water and the way they eat is amazing to watch.
Another thing that I like about them that puts them above other large cichlids is the fact that they do incredibly well in groups. I'm also very fond of the parachromis genus but you couldn't keep them in a mixed group. They interact with each other very well and live as a pack. Finally one thing that I know a lot of my fellow cichla friends love is the variety within the genus. There are loads of cichla species and a number of variations or locales in each species so there is always something different out there.
If this doesn't explain it here's a video of my pbass to demonstrate why I keep them.
