Unfortunately this tank was torn down and the shrimp were moved into another 1 gallon
(I need to get an updated picture). I put a PAR 20 led on the tank for a week or so and it was way to much light which caused a thread algae breakout.
So as far as lighting I'm using a really cheap LED E27
that I bought on dx.com. It is a 3x1watt bulb. I get pretty decent growth on my current tank, typical it gets trimmed once or twice a month.
I've also used a 9watt CFL which works well for a tank this size. If you can find a PAR 20 in 5000k and can pull the light away from the tank that would look nice
not sure about the sword, I thought it was chain but its been a while.
