Hostile Blub Leg Hermit Crab?

[dilbert]

I feed them frozen brine shrimp daily and the live rock has plenty of misc. algae and goodies to munch on.

What would make my crab do this?

Some author described them as "reef terrorists". They are lazy little villains.

Mine, that is Herman, eats even cyanobacteria when he's hungry, but lays lazy on the sand doing nothing for a day or two when I fed him.

To get him doing his job of eating algae you need to kick him *** and there has to be no other food around.

hermits personalities differ greatly, The nastiest BL I've had actualyl would go around to the others, rip them out of the shells, and kill them. He did this to about 4, and when I caught him in the act, he quickly was transferred for processing to my octopus tank.
