I found this little guy in my tank tonight. Any idea what kind of crab he is? I originally thought Emerald when I first saw him, but I don't think so. My wife thought it was a Sally Lightfoot. Any guesses?
my guess would be a porcelain crab. Check the pic on here and other sites to confirm. The pic on here makes them look purple, but that is the lighting.
I would deffinately not put him in a reef. I dont know what kind it is, but it does not look reef safe. Most hithiker crabs are not reef safe and will grow large. MOst either eat fish, clams, snails, and some even corals
