Emerald Crabs

[SmoothSmoke]

Ive read that emerald crabs may eat your corals. Which corals in specific can they have an appetite for?

i have them in my tank and they do not really eat the corals but they bug my scans like crazy, especially after I feed them. They pry open their mouth and steal the food

I have had one for almost a year and have had no problems with him.....actually I have only seen him a handful of times lol.

Crabs are oppurtunists. As such they are looking for the easiest meal possible. Scavenging for uneaten food and algae is easier than eating a healthy coral. Stealing food from a coral is easier than eating a healthy coral. However, if a coral is struggling and there is not much food available an emerald crab may go after it.

I have a bubble algae outbreak in a nano. Need an emerald but am afraid that it will eat my coral. Ive read that female emeralds are better. True?

I've had zoanthid frags and a pipefish disappear after putting emerald crabs in a tank.
