Before I recently traded them in for some credit towards a jardini arowana, I owned 5 red bellied piranhas. I noticed they would only eat food from the surface or as it was floating to the bottom of the tank but soon as it hit the gravel they where done. This caused alot of problems with the cleanliness of the my water so one day I purchased a regular crayfish from the store for $2.99 to do some clean up work at the bottom. He was an absolute riot! He would spend all day and night chasing the piranhas and feeder fish. He did a great job of cleaning my tank but eventually caught and ate a piranha! Unfortunately as soon as the poor guy molted they turned on him. Now I have a blue crayfish in the tank with the jardini and he spends all day hiding. Did I have the norm or the exception?

Cheers,

I see allot that just hid.
 
My crazy blue crawfish keeps climbing up and going into my overflow! Its a huge pain to remove all the bio balls in there to did him out! I'm leaving him in there for the week!
 
I have two. My blue Cray i never see. He hides in a cubby hole. I literally have to pull it out of the tank just to see if he's alive. Cuz ive yet to see him eat.

But than i got a Albino. And he's an absolute blast to watch. Just like you describe. Always into something.
 
My crayfish walks around my tank and he just tries to grab any of my plecos or comets. But he never actually grabs them! He just stops as he approaches them. He has not grabbed any of them! Only eats sinking pellets! Cool little guy!

This is greatly determined by the type and size of the cray.
Many crayfish are burrowers who spend most of their life in burrow they dig in the mud. They adjust the depth based on the water line. They will close the door to their burrow (covering the opening with mud) when it's too hot or cold and of course most have a backdoor to escape through!

Other crays are river/stream dwellers. Some of these are quite bold and are often quite active.

On the whole they all like to hide, and it's best for them to be able to get away after moulting.
