Whitening Emerald Crab

Hi all,

Over the course of four months, my Emerald Crab has gone from very green to having lots of white blotches all over its shell. Is this indicative of a problem, or normal? How long do these creatures typically live, as well?

Is he running out of algae to eat? Sounds like it could be a nutrient defficiency. How old is he?

Definitely not running out of food! It seems to prefer coralline algae, and there is tons of it on the rocks. It's about 4 months old.

Hrm. I thought Emeralds prefered green algaes?

Mine's a freak. It only has 7 legs! Surprisingly, it ignores the hair and bubble algae in the tank and voraciously scrapes coralline from the rocks.

It could be getting ready to molt.
