WHATS THIS ON MY CRABS CLAW (aggression?)
just in june i introduced a new crab (taco) to my tank for my single crab (chalupa). there was a bit of pecking order that went on as chalupa is a bit larger, then they both went down to molt at the same time and both came back up around the same time. chalupa (pictured) had been up and moving around and chilling on the surface while taco has been coming up and down. i found this on her claw after a week long trip. i put a mountain of food in there and a dish of coconut oil. could this be the result of aggression or some missed skin from her molt? (apologies if i used the wrong flair)
