Cause I find most other fish "boring".

I don't understand discus owners - I find fish that are floating kinda boring.

SA cichlids are nice, but I had to go with Malawi's for their color and their character.
SA apistos have some really nice colors!
Most will recommend 30G absolute minimum.
Most will recommend bigger.
I started out with a 10G, which was obviously too small, but now they are all in a 60G and happy!

One drawback is that these things are not very good community fish.
If you have your heart set on a mix of fish in your tank, getting cichlids to mix with other species is an exercise in patience and research!
Lots of the species get BIG.
So you really need to do your homework.
I try to stay with relatively small species, and there's stuff that will stay even smaller.
"Shellies" and drawf apistos should keep pretty small...
