can you ID this shrimp?

[KEEPitSTUPID]

hi,
i recently bought this shrimp ( and i use the word shrimp loosely) because of the terrible conditions it was being kept in, and because it was so good to watch. so what i mean by loosely is its around 12" long from tail to claw, and killed two 10" plec whilst on display in the shop. its long blue claws and size seem to make it a lot different to others i've looked up, i haven't came close to finding it on shrimp sites and shrimp breed lists. was sold as vampire shrimp buts a lot different to them, and bigger, so my huge question is, what is it?
but diet and life span and living requirements and anything you know would also be greatly appreciated.

Can be very mean. Almost have to by them selfs. They can eat feeder gold fish too. and get BIG!!! All i really know on them so not a whole lot.

They can get to 12" and they eat fish, and they are extremely agressive. Lots of people sell them unscrupulously as being community tank oddballs.
