Fie

It’s only really obvious when Fie gets wet but boy did she/he turn blue after the most recent molt!
Coenobita clypeatus aren’t typically a true blue color. This is under a bright white led light as well. Many of my crabs are taking on this dark, rich color pattern. I wonder if it’s the worm castings or greensand causing it? I keep them both in the tank at all times now.
