They are copepods that LIKE to be on the glass  They eat film alga and other microscopic goodies that are on there. The larger, gammarid isopods are often found in rocks, sand etc. and it is THEY who would be bothered by the crab. BTW...best of luck with the horseshoe... they get large, become true bulldozers and typically need square YARDS of sand, rather than feet, for hunting and survival. Dave |
