I have a 75 gallon that I started around December 8, 2011.
My CUC consists of:
2 Turbos (1 suffers from "up side down" disease)
3 Margaritas
5 Blue Leg Hermits
2 Nassarius
1 Stoma <- LR Hitch Hiker
They are cleaning the algae very nicely. Slowly, but I am not in a hurry. I don't ever want to starve any of them so I started with just 1 Margarita, 2 Nassarius and 1 blue leg hermit. Added the Two Turbos and 2 more blue leg hermits a week later and a week later added two more Margaritas and two more blue leg hermits. I first noticed the Stoma about a week ago.
I'm pretty happy with this small crew. The one hermit crab hardly ever rests or even stays in one spot for very long.
