Very sneaky with the lights there. If they are T5HO with individual reflectors 2x24 watt bulbs will put you solidly in the medium light category. Unfortunately at medium light the HC probably won't survive without CO2 and ferts. (HC is actually this July's Plant OTM, check the main planted aquarium page stickies.) If you are interested in doing ferts check out EI method and PMDD, also can be found in the stickies.
Be careful about adding plants/fish from local waterways. You could get all kinds of hitchhikers.
