How many gallons is this tank?

Thx, will check them out when I go to get the gravel tomorrow, about how many watts do you think I'll need?
 
I've seen 23W 'daylight' bulbs, they're larger than traditional household incandescents, but if they'll fit they'd probably be quite bright. You might be able to find screw-in bulbs in higher wattages, but they'll probably be fairly large. If the fixture fits standard lightbulbs and a larger CF bulb won't fit, there are 'mini' CF spirals available (similar size as household incandescent bulbs), but I've only seen them in 15W.
 
Yeah, I was thinking 15-20w would be good if I had 3 of them.
