Emerald Crab or Not??

[Hemiseller]

This little guy has the exact same body shape as an emerald but has a funny color pattern. What is he??

 

[AdamNC]

No idea but definitely not an Emerald.

 

[Vaughn17]

Cute but evil, no doubt.

 

[Hemiseller]

So evil?? Should I take him out because he is doing everything exactly like my other emerald. He even looks the exact same except for the color.

Look close at it's pincers - flat like an Emerald, or sharp?

Just going to ask that myself.

 

[Hemiseller]

After close examination the pinchers are the same as my emerald crab I already have that is normal color. These two pics are crap but the best I can do with a phone camera.

Crabs are tricky. just when you think one is going to behave, they will start eating your favorite coral or fish will start to disappear. I have had several that were considered "reef safe" only to wreak havoc in my tank. Now I only go with tried and true like emeralds. Also blue leg hermits, but they will sometimes take out snails.

Decorator Crab.

I'm a big fan of crabs in the tank, but I treat mine like fish rather than CuC. Without better photos I can't really ID this guy though.

 

[Roboson]

Best guess: Mithraculus cinctimanus.

Crabs are all evil in my opinion. I go to great lengths to remove them 100% from my tank. But he does look cool with those white claws.

 

[Hemiseller]

Roboson,
Ok I will work on better photo for an ID.

 

[Roboson]

Best guess: Mithraculus cinctimanus.

Just google that guy and see if he's the same.

 

[Hemiseller]

I did and he look the exact same as this one Mithraculus cinctimanus.

 

[Hemiseller]

He is also known as the Banded Clinging Crab and loves to hang out by anemones if my research is correct. My little guy also hangs out with my nem so seems to me this is exactly what I have.

Only crabs I like are soft shelled and on a sandwich...

 

[Roboson]

Yup, they're really cool guys. All mithrax (clinger) crabs are cool. The living with a nem behavior is especially interesting.

I used to have an Emerald share a RBTA with a Maroon Clown once. Definitely a weird relationship there.
