Ideas/suggestions for a 20g appreicated.

[torch89]

I'm kinda lost at what to do with my second 20g.  My other tanks are planted, but I don't want this one to be as I don't have good lighting for it.  One thought was to move my male Kribensis into it and purchase a female to go with him, but I think then they would be the only fish that could go in the tank as they will probably get territorial if they spawn.  Does anyone have a pair of Kribs in a tank this size that they were able to add other fish as well??  If so, what type of fish?  It seems a shame to have a tank with just two fish in it, even as interesting as they would be.  By the way, I love my Krib!!  Personality ++.
Not sure if the above is the way I will go though, so wondering what other combination of cichlids I could actually have in a small tank like this.  Any suggestions would be welcome.  Just looking for ideas and as well, decorating suggestions.  Will be in Ottawa soon, and will have to transport the fish home (8 hour + drive in a cooler).  Something unusual or with good character might be an idea. 
Appreciate any input.

Maybe a shelldweller tank: ocellatus, multifasciatus or brevis.  This may be a bad idea because you're going to buy a very large tank and put africans in it once you get the bug.

Thank you for your response.  I did some research on shell dwellers.  Not sure I will go that way right now, but very interesting sound fish for sure.
