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.
Do skrimps keep thr aquarium clean?
Ehhhhh they help but as you can see they don't get all the algae.
I don't think they eat brown algae, on account of it being diatoms.
Sounds like you need more shrimp. Or the one from finding nemo
