New fish - what to get?

[Rex]

Since I am selling my ~35cm Saratoga, I need to decide on some new fish to put in the tank.  Its a 4x2x2 and currently has:
1 x ~25cm sailfin pleco
2 x small plecos (<10cm)
5 x clown loach (<10cm)
1 x tiger oscar

I can get rid of the tiger oscar aswell if necessary but would be nice to keep him.  I'm looking for some nice fairly active fish that will get along well with the current inhabitants, I'm thinking Americans but not sure which ones.  Anyone got any suggestions?

i reckon you should get some africans in there maybe a nice few yellows and blues and i recommend a pair of humpheads they are the coolest fish 8)
