Yeah it probably would be hard to get a photo. When crawfish get frightened they launch themself backwards and man can they go quick. One time mine launched herself so hard she came to the top of the tank and then floated back down lol.

And cinderblocks may work. I wouldn't be too scared to hold them. It really depends on size. If they are as big as mine or around there then their pinchers wouldn't hurt that bad.
