40 gallon bowfront stocking?

The dimensions are 92 cm Width, 41 cm Depth, 55 cm Height. The tank is fully cycled, the filter is a Fluval 205 canister filter, there's a bristlenose pleco in there already. I want a community tank stocked around tetras namely the black skirt,red eye and serpae tetra. I know they like being in groups of 6 or more, is there any other fish (besides the angelfish) I can put in with them. Or alternate stock lists would be very appreciated (doesn't have to include all 3 tetras I've metioned.)
