Here's a quick video of my Tiger Pistol and YWG. It may give you a better idea of whether or not it's the same shrimp you have.

Ok, thanks.Yeah, there are actually quite a few Alpheid shrimp that look superficially similar to the Tiger Pistol Shrimp, Alpheus bellulus (such as A. rugimanus, which I've seen stores starting to sell as Tiger Pistol Shrimp recently) - some of them may not be as peaceful as it is (some Alpheus species are confirmedly not reef-safe, I haven't looked much into how safe ones that may resemble A. bellulus are though).
OP, if you can get some clear pics of the top and sides of the shrimp under white light, I may be able to ID it for you - as is, I will say I'm doubtful that's an A. bellulus, as the pattern looks slightly off on the top (particularly by the head), and I can't see the typically fairly ornate patterning on the sides (there is some variation in the pattern/color to these shrimp, but yours still looks off from all the variations that I'm familiar with from what I can see).
Pistol Shrimp tend to get a really bad reputation that (from what I can tell) isn't really deserved. A true A. bellulus or A. randalli (the Randall's Pistol Shrimp) should be peaceful/defensive - they really shouldn't go hunting at all.
Bit of an info dump here:
Anyway, OP, to try and rule out other potential causes: Are any of the fish exhibiting other issues - things like fast breathing, white spots on the body, etc.?
I've done my best. I stripped the tank, and dug him out. The two missing fish didn't appear, so my vote now is they are gone. I've attached everything taken, so some are likely blurry. The video was taken from another device that was able to focus on him better.Yeah, there are actually quite a few Alpheid shrimp that look superficially similar to the Tiger Pistol Shrimp, Alpheus bellulus (such as A. rugimanus, which I've seen stores starting to sell as Tiger Pistol Shrimp recently) - some of them may not be as peaceful as it is (some Alpheus species are confirmedly not reef-safe, I haven't looked much into how safe ones that may resemble A. bellulus are though).

I can see the video - as a tip for the future, though, most people upload their videos to a site like YouTube and then link the video here from there (Reef2Reef struggles with videos sometimes).Video didn't seem to add. And forgot to mention how the shrimp is bigger than the two fish that went missing.
If it doesn't add now, I am not sure 100% what to do. As this video is the clearest out of them all. And this is a shortened version of it
Thanks, I can see if I can dig him out of the pest tank? Or would that be too much stress to catch him twice in one day? So you want a picture of the head and tail from above, the side where there is a dark mark from the side and the second pair of walking legs from the side?I can see the video - as a tip for the future, though, most people upload their videos to a site like YouTube and then link the video here from there (Reef2Reef struggles with videos sometimes).
So, your shrimp is definitely from the Alpheus djeddensis – Alpheus djiboutensis complex; I've seen a bunch of places (at least five or six) selling shrimp from this complex as Tiger Pistol Shrimp, which may explain some of the difference in reported behavior from people. I'm guessing your shrimp is Alpheus sciolii, but I would need very clear, straight-on pics of the head from the top, the tail from the top, the side near where the head and tail sections of the body meet (specifically of the big dark spot) from the side, and the second pair (second from the front specifically) of the walking legs.
Alternatively, if you know specifically which ocean/region of the ocean the shrimp came from, that can also be useful for ID purposes here.
For some good pics of species from the complex to compare with, you can look through the links below:
(Figures 7 & 8 - specifically C & D in 8)
(Figure 2)
(Figure 8)
I'd probably give the shrimp a day or two to be safe, then catch it and put it in a shallow container of tank water for the pics (if you can get a black background behind it for the pics, that would be ideal).Thanks, I can see if I can dig him out of the pest tank?

Thanks, it will likely end up being after the weekend. But I'll see if I can attempt late tomorrow maybe.I'd probably give the shrimp a day or two to be safe, then catch it and put it in a shallow container of tank water for the pics (if you can get a black background behind it for the pics, that would be ideal).
Yeah, head and tail from above (I need to be able to see the middle parts of each clearly, and a couple extra parts next to the middle parts of the head), the dark spot from the side (preferably without a leg in the way), and the second pair of walking legs from the side and/or front (I need to be able to see the relative length of one of the leg joints/segments on that pair of legs).

Hopefully these work, I attempted a black background but he was never in the correct place for it.I'd probably give the shrimp a day or two to be safe, then catch it and put it in a shallow container of tank water for the pics (if you can get a black background behind it for the pics, that would be ideal).

These are a bunch of great pics - you got the tail perfectly, and it reinforces my belief that you have an Alpheus sciolii (the middle part of the tail - called the telson - is used to distinguish Alpheus sciolii from Alpheus djiboutensis; broader telson = A. sciolii [which is reported to have the broadest telson of the complex], narrower telson = A. djiboutensis).Hopefully these work, I attempted a black background but he was never in the correct place for it.
There is a lot of photos, probably some not in view/blurry, but I hope that there is correct ones among them. If not I'll see about getting some more.

Mine most definitely was a gangster. YMMV but I'll never get the tiger variety again.All my pistol shrimps have been model citizens. Im always a bit skeptical when people say their pistol killed anything. They have a water jet to deter other inhabitants away not a Glock.
