How Many 'fans' Do Bamboo Shrimp Have?

[214jay]

I have two shrimp in my large tank that were sold to me as Armoured Shrimp, however they are clearly some form of Bamboo Shrimp (look more like Asian Filter Shrimp on google images), they have 4 fans each.
 
I have another shrimp in my other tank that was sold as a bamboo shrimp but he only appears to have 2 fins!  Does it sound like he has lost 2 or is he a different species?

Bamboo/Rock Shrimp have four I believe - mine certainly do.

Type bamboo shrimp on google images, look at the pictures. then do an armoured shrimp image search. Compare the pics with your shrimp

You can tell Armoured Shrimp(also called Vampire Shrimp and African Filter Shrimp) from Bamboo Shrimp just by looking at the body. Armoured Shrimp are very thickly armoured(as suggested by their name)...
 
As far as I can tell by looking at my friends Bamboo Shrimp they have 4-6 fans... I can't quite tell though because he's shy and hides a lot so I'm looking through about 20 plants...
 
Here's some nice close-up pictures of both Bamboo Shrimp and Armoured Shrimp fans

And full body shots of each.

Thanks everyone for the replies.  The pictures are a great help (and also great).  I would say they are all Bamboo shrimp looking at this, I guess the smaller one has lost two of his claws at some point.

No problem

The claws should come back after they moult so don't worry
