BORING?!?!?!?!??! what are you talking about??? I think they are pretty neat. I had a bunch of them in a ten gl community tank and they were the most instering thing in there. I didn't give them many hiding spots so they got used to the light and became very friendly with me. they knew when it was feeding time and they would go crazy.
my biggest cray got to be about 7 inches b4 he died due to some medicine i gave the fish......
