The pictures help, they fish certainly does not appear to be a cichlid! They are not that clear though. Can you confirm the fish does not have an adipose fin, (small fin on the back between the dorsal and the tail)? That way we can rule out a Parodon species for example.
Opsaridarium chrystyi is commonly called the "Gold Lipped xxx" where xxx is variable, the gold lip is quite characteristic, so if you have a gold lip on the fish, that is probable. There are other Opsaridarium species which are similarly marked, O. zambezense for example.
Another group with species looking like that is the Raiamas group. R. moorii or R senegalensis for example.
There are a lot of new small cyprinids, Danios etc. coming along at the moment, particulaly as Burma is becoming accesible now, could easily be another of these. Frankly, I think that is more likely than the other suggestions I've made simply because more people are exporting these things than the other groups which are from Africa.
Whatever, it is a nice looking fish.
