local beach crabs in a reef tank

[langley reefer]

I have a story to share. Probably about 15 years ago a friend of mine put a tiny.little crab he found at white rock in his ninety gallon reef. The crab promptly hid and was never seen again. Fast forward about a year and my friend was ver excited about adding a beautiful yellow and purple baby ribbon eel. All was fine on the first night but when he woke up the next morning and looked in his tank and found that crab about 20 times larger with the body of the eel in one claw and the head in the other. Most of the crabs on.local beaches are rock or mud crabs, which are predators.
