I just came down stairs to check my tank and this da@# hermit crab was trying to eat my yellow watchmen goby. It looked like the watchmen was going to let him. At first i thought the watchmen was dead. I stuck my hand in the tank and he took off. I grabed every crab i could find and tossed them in the sump. Any one ever seen this before?Now the watchmen is back out of his hole hanging where he stays most of the time.
