Hi,

I started an approx 1 litre aquatic sphere a couple of months ago. Two ghost
shrimp died after a couple of weeks. Guess I was overly optimistic with them in
that container. A 0.5 in diameter snail remains. He/she keeps the glass quite
clean, though I'm getting a thick buildup of algae on the two plants.

When I start another, I'd like to have an algae consumer to keep the plants
somewhat clean. Any ideas?

Steve
