The Saltwater Emerald Crab is a great addition to any aquarium and is reef safe. They eat bubble algae and are very easy to take care of. Ample food needs to be present for them though as they will clean all the bubble algae out of the aquarium. Supplementing seaweed or chopped meaty food will suffice for them. They are also scavengers and will clean out most organic debris from the aquarium. | |= COMMON NAME: ||= Emerald Crab | |= SCIENTIFIC NAME: ||= Mithrax sculptus | |= SIZE AVAILABLE: ||= ~1/2 inch | |= MINIMUM TANK SIZE: ||= 1 per 25 gallons | |= FOOD/DIET: ||= Omnivore | |= CARE LEVEL: ||= Moderately easy | |= REEF SAFE: ||= Considered safe, may be aggressive | |= AVAILABILITY: ||= Most always available - 99% | *Easy to care for and considered reef safe. *Recommended stocking is 1 per 25 gallons. *A crab with a green exoskeleton and "hairy" legs. *The Emerald is an EXTREMELY hardy creature that can survive a lot of harsh conditions.

I bought one of these guys and I feel in love. They are amazing to watch at night. They say they are reef safe but all aren't. Mine decided to pluck off my 'sorry I'm blank on the name. Its a coral that looks like grass growing. I actually watched him for a few min. To be sure he was eating it. Yes he was, so I had to put him in my sub. Tank. I still love him. He's gotten really big so he's healthy. Just be ware.

Awesome Crabs!
Bought my first two from here several years ago for my 55 gal. When it was time to stock my upgrade 180 gal I knew where to come. Great customer service and awesome livestock. What else can you ask for!

Buy 1 get 1 half missing
I open up the bag and found 1 health looking Emerald Crab (Mithrax sculptus) and another one MIA? I found a 1 claw and i think the bottom half of the head? I guess the other guy was hungry! Other than that the live one is striving and doing a great job!

The emerald and ruby mithrax crabs I bought from you arrived well and are growing and gobbling up the algae at an amazing rate. Every one should have some of these.

Review of Emerald Crabs
I ordered two of these fellows and both arrived alive and well. I put them in my tank and they seem to be doing just fine. Another great purchase from Reefs2Go and fast service.

Emerald Crab Review
These Emerald "mithrax" crabs are the BEST for removing unwanted hair algae. They pretty much keep to themselves, and are fun to watch!
