Addressing your thread here:

Mantis shrimp algea like growth on back

So ive gotten what i think was a male shrimp about a week ago. Since i got it ive noticed this weird algae like growth on its back. Does anybody know anything about this, is it bad, can i do anything about it. Its eating just fine. Its in a 110 liter aquarium. I can't really take a good picture...
