I have a Mbuna Lake Malawi 29 gallon tank that is planted with 2 anubias plants and 6 amazon swordtail plants. It is currently holding (1) 4" red zebra, (1) 2" yellow lab, (1) 2" elongatus, and (1) 2" Jewel cichlid. What tank mates would you recommend for this set-up? The tank has a higher pH, around 8.0-8.1, so I am looking for something that is hardy and can tolerate more alkaline water parameters (higher pH). Preferably something that has A LOT OF COLOR and will stand out against my charchoal/dark slate background and my black gravel... 
The tank (NOTE: The goldfish were temporary and have already been disposed of by my Jag):
