Can Someone I d this pistol Shrimp?

[James32]

Hi I have the same pistol shrimp in my tank that is in the video in this link
http://www.youtube.com/watch?v=qfncSaK9ciw I bought it from North American Fish Breeders In Toronto Canada with a Yellow watchman Goby needless to say they were not a match and did not pair later I bought a tiger pistol to go with the goby and the other shrimp got bigger he looks exactly like the one in the video I would love to catch him as he has killed my yellow watchman goby my dragon face pipe fish 2 of them and 2 Queen conches...
But if I can figure out what type he is maybe I could get a goby to pair with it and that may keep things away from it and help keep him fed? Also I have not seen the tiger pistol in months I have 180 gallon main tank with 115 gal sump and 75 gal frag tank all one system . Both pistols are in the same 180 but the only one I know is still alive is the purpleish one in the video I found.. Any suggestions would be helpful.. But please don't tell me I should have done my research first and all that. Cause I did and everything doesn't always work out like books and people tell you it will some things we all learn the hard way...
Cheers and Thank you in advance

I remember seeing one similar to that & it doesn't pair with gobies. I can't remember which pistol shrimp it is though. Sorry.

I had one of these and believed it was Alpheus immaculatus http://www.reeflex.net/tiere/5019_Alpheus_immaculatus.htm It wasn't a problem with tankmates but it isn't a pistol that will pair up as far as i'm aware and i wouldn't mix it with another pistol. tigers can stand up for themselves and reach a similar size but these are pretty well armed.
