SRC Member epicfish Posted August 24, 2013 SRC Member Share Posted August 24, 2013 Probably just a shed. Crabs are crustaceans, they go through a mold process like shrimps. Also, crabs can regrow claws if i recall. So its not uncommon to find these in your reef. Quote Link to comment Share on other sites More sharing options...

SRC Member domvonn Posted September 2, 2013 SRC Member Share Posted September 2, 2013 Comparing to the sand size .. The crab shud be at a undesired size . Quote Link to comment Share on other sites More sharing options...
