Brad and boB,

The problem is that I have no idea which rocks harbour the bad guy(s). Would using RO/DI or very dilute SW water, say with a salinity of .300 instead of the regular 1.026, instead of soda water be less harmful to the rock overall, but still flush out the crabs and the thing doing all the clicking?

I don't necessarily want to kill the crabs, because I know that at least two of them are beautiful and harmless filter feeders and another is an algae eater. But I would like to find the other crabs and clicking thing, and do as little harm to the rock as possible.

Any other ideas than those I have suggested?
