Emerald crabs are always cool! Lost mine to high nitrates last time but replacing my clean up crew, he was first on the list! Fun to watch eat fun to watch grow.

These crabs appear very busy picking at the rocks and sand. They seems to be good cleaners. They leave my fish and invertebrates alone. Good addition to the tank!

Very nice little crab. Fun to watch. He has already molted twice since being added, went from a brownish color now turning green.

Emerald crabs I love my emerald crabs. I have 5 and can always see at least 3 at a time working on my live rock. They are fun to watch, actually it's relaxing! They are out and about and very enjoyable!

A lot bigger than I was expecting!

I received one as part of a reef pack. While it is usually hiding most of the time, it makes appearances once my tank moves to moonlight LED. I have a feeling he is nibbling on the edges of my mushrooms as the other inhabitants are completely reef safe. Arrived happy and healthy.

Came in good condition. Adding rocks to the tank changed water condition, but they survived.

Excellent addition to my tank

Very healthy very cool

Very fun to watch. I ordered two for different tanks. One was a very light color while the other was very green. The cleanup crew has been doing great at making my tanks look better

I received a very healthy, nice size Emerald. He's very active and of course very funny. Love this web site!

Very interesting addition to a reef clean up crew. Likes to quickly hide in crevices.

Another family favorite to watch them nibble on their food and climb throughout the tack. Very nimble! They walk around like little boxers and walk sideways in the sand. Doing a great job housekeeping.
