red....
I honestly dont know thats why he is in my sump. the pointy claws would indicate that he is not exactly reef safe. he should make a good scavanger though. If any one can Id him that would be cool. he was labled as a "red fiddler crab" no filler claw though so i think its a mis'ID
Great link wfd1008, I didnt see my little guy on the list though, there are some really cool crabs on there. a couple I wouldnt mind adding to my tanks.
