Have a look at my stock list in my signature/profile for my 50g. OK, it's a 190L not a 180L, but not a whole lotta difference. Ignore the Geo (he will be going in my large tank eventually) as Wills said they will need a bigger tank long term.
I really, really recommend Praecox Rainbowfish, they are fantastic. I have 12 in my tank and they add such colour and activity to it. They also encourage the shyer dwarf cichlids out and make them more confident.
How about a school of the Rainbows (can't have any larger Bows in a 3ft tank, but could go for the smaller Rainbows like Threadfin or Blue Eyes instead), a couple of Bolivian Rams and some bottom feeders like a small Plec, Corydoras, Khuli loaches.
Or you could get a pair of mid-size cichlids, with some dithers?
can u give me an exact stock list of ur 50g tank including quantities?
