when i first got into fish (only like 2 yrs ago ) i had a 10g witrh normal gravel and incandescent lights... and i bought some aponegoten ulvaceus bulbs from walmart (the dry bulbs that come in a package) and they did great... i didnt use co2 or anything... but they might do better if you could get a lil more than 1 w/g tho'
