cleanup crew

[DJ Oetting]

hey guys!!

I just wanted to get some opinions on what would be a good cleanup crew for my 20g nano

In my 15 gal, I have x5 tiger trochus snails for rock / glass, and had x5 nassarius for the sand bed (down to 4 now).
They have always kept up and never had a problem.

In my 29G I have 3 small and 3 large nassarius and 7 cerith snail's.
