Mollies come in different colors and are related to the swordtails. They are fun fishes.

I don't know if swordtails/mollies will be safe around a cichlid. We have two and they are pretty agressive fish. Since we restarted our tank about four months ago, we've had six and are now down to two...they eat eachother. So keep that in mind if you're thinking about those or other agressive fish.
