Sorry about the algae, but they likes it so I leaves it.
Also thats a shed skin stuck in the soil to the left, not a dead shrimp.
A blurry picture, I know, but these little guys are like 1 inch long and behind glass and water so my camera doesn't like taking photos of them.
They are cool but it's annoying not having anything to eat the dertritus worms and other pests that grow without fish to kep them in check.
