Hi everyone! I'm new to a marine tank hobby and have a question. I have 3
small algae crabs in which 2 changed their shells to larger type shells last
evening. This morning there is a pinkish/clear looking crab like "thing" on
top my substrate. It's shaped like a crab and it's color is pinkish/clear
(something like the color of a shrimp). Is this the exoskeleton from a
crab? I'm sorry to be dumb at this but like I said I'm new to the marine
tank world.

Thanks in advance!
Susan
