Space is not the problem, but I would not put Melanotaenia boesemani
(Boesemani Rainbowfish) in with smaller fish, as they will attempt to eat them. Rainbow males can grow to over 4 inches, and according to reports will attempt to eat any fish smaller than about one inch. They are peaceful community fish with similarly-sized fish, but not smaller fish like neons and similar.
As you have the neons now, some thoughts on suitable tankmates if you want slightly larger fish would be dwarf cichlids from South America (species in the genera Apistogramma, Mikrogeophagus, Dicrossus) or some of the peaceful larger characins (Congo tetras, diamond tetras...). Of course any of the dozens of tetras would work, and in a 50g you could have several species with 7-9 of each. In a well-planted tank, beautiful.
