Mayan Cichlids? Jk, I know the tank is too small.
You didn't buy this off of Craigslist? I saw a similar one for sale around here not too long ago (actually maybe a few months or so).
I have to agree with AirstoND, at least that's what I would do.
But if you are stuck on Africans, then you would obviously have/want to go with the hardier plants, like anubias, "ferns", maybe jungle val, etc.
I'm pretty sure you know this, but with Africans, they prefer to have multiple hiding places (e.g. rocks).
