nicely. Some folk like red claw hermits, in their clean up crew.. I never
bought any, the blues do a good job so.. Also I'm not sure what the
difference is in terms of how much or what they eat.

I've had both. The reds are more omnivorous and seem to fight more than the
blues. I haven't tried emerald crabs but none of the others last long for me.
Dunno why. The blues last the longest, though. Several months, at any rate.
