Pairing fish you could consider: Cockatoo dwarf cichlid, bolivian ram, kribensis.
Sorry to dispute you Corleone, but IME whilst kribensis can be kept in community tanks, I do not think they are best suited for them. I have one in my cichlid tank and he chases my green terror around! I kept losing neons when I had a different pair of kribs in my community tank, I eventually gave them to the lfs. Strangely enough since then I haven't lost any neons! Also beware as they are bottom dwellers what other bottom dwelling fish you might like to have. Kribs will defend their territories and IMHO a tank 62cm long wouldn't be big enough for kribs and other bottom dwellers like corys or plecos.
I do agree that cockatoo dwarfs or rams would be great. These are New world cichlids. The krib is an old word cichlid, which are in general much more aggressive.
That said, it all depends on the indiviual fish!
