Hello,

I am looking for some advice on how to light this 2.3 gallon tank I recently got. It's about 7 inches tall and 18 inches long.

As of right now, it has two 10w CFLs mounted right on the glass above the tank.

Is this too much light?

Due to the length of the tank, one light raised above it wasn't lighting it very well so I figured I'd need two.

I like how mysterious the top photo makes it look, sort of like a shadowy alley in the grimier part of fishtown lol

2 should be fine, I would just make sure you have enough space between the lamps and the water surface to prevent excessive light at substrate level.

Also, those are some very unusual dimensions for a 2 gallon.

Thanks for the reply.

Yeah, the dimensions are different... I really like the footprint of the tank.

I will probably just stick with the two 10w CFLs then. I was worried that this would be too much light since it's only 7 inches tall and 2 gallons.

Also, I'm not using CO2 on this tank - just excel. Not sure how much that affects the lighting.
