I hate to bring you bad news, but the Kenyi needs to go. Like, now, before it gets bigger and kills the rest of your fish. Malawi Mbuna are far too aggressive for the other fish you have. The 2 plecos are questionable with the rest of your stock just based on bioload... with a lot of water changes, you can probably make it work. The dwarf gouramis may fight if they are not a M/F pair.
Closer to 30G, sorry we use litres rather than gallons here in Australia.
The kenyi already has a new home which he will eventually move to. I got 3 cichlids as gifts from a family member and I've slowly been re homing them.
