I found this small red crab, except it has white stripes alternating with the red. It does not have a shell, looks like a green emerald crab, except its body is red but has white stripes. The claws looks to be the same size.
Should I be worried? anyone know what kind of a crab this is? Will it hurt my corals? I saw it grasing on the liverock, trying to eat algae im guessing. I tried to get it out, but it hid away inside the rock. I searched on google but could not find what type of a crab this was.
