Can anyone ID these shrimp?

Hey everyone, someone I know has asked for the ID of these shrimp, they are approx 20mm in size. The first pic is without a flash & the second is with a flash. When I saw them I thought of asking the collective knowledge on here. :encouragement:

Good pictures, the best I could suggest is Caridina indistincta (at a rather long shot) but more likely Paratya australiensis. Actually the eggs have got me a bit stumped for P. australiensis the eggs should be smaller so I am thinking maybe a Caridina species after all.

Do you know where the friend got the shrimp from? If locally caught in their area it will help with pinning down its id. If they came from unknown sources then its going to be more difficult.

Yeah I'm trying to find out where they got them from, just waiting on a reply :encouragement:

They look like two different shrimp. The top one looks like Indistinct and the bottom one has no rostrum? and the egg size it looks like it is from the Atherton table lands?

Where they come from will help, As always the point I try to get across to every one with native ID is, the first and major point is identification is the nose then feet and swimmers, colour has nothing to do with it except for Serratirostris, nothing has the patterns they do and there nose is distinct.

I noticed the female was missing her rostrum, but thought maybe it had been damaged during net capture?

I think they both maybe the same species (mainly if the rostrum on the female has been damaged and not naturally absent), the more male looking one could just be younger. I know my native mystery shrimp have changed quite a lot since I originally got them.

Is there any chance the friend can get photos again of both shrimp both with and without a flash?

Good point Bacc, I down loaded the photos to my computer (dammed if I know how I did it but I did yea) and the Female looks like it is broken off but the serrations on the Rostrum behind the eye are the same.

With that egg size my call would be C. short ck or C. confusa?

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.

      Hello! I have a tank that currently does not contain shrimp, but does contain neon tetras which I am currently treating for Ich, as well as some bladder snails. Shrimp will be a later addition, likely cherry shrimp but I'm still doing research just to be sure. Initially I'd intended to buy some sort of Ich-fighting product that contains malachite green after doing a decent bit of research on it, most of which indicated that it should be shrimp-safe so I'd be good if I ever needed to use it again once shrimp were actually introduced (though I should note I'm aware shrimp can't get Ich, I'm more wondering in case the tetras could get Ich again, or something else that responds to similar medication). I ended up not being able to find any MG-containing products without either having to travel quite far or wait multiple days for delivery (which I was worried could lead the Ich to be fatal), and ended up picking up 'Top Fin Ick Remedy', a product that contains gentian violet which is a triarylmethane dye like malachite green. The bottle has two slightly differently worded warnings about its use with invertebrates ("not recommended for" and "not safe for" respectively), but when I'd been researching malachite green, I'd also heard of products that contain MG but not any other ingredients that would be harmful to inverts still being branded with warnings that they could be harmful, just as a "just-in-case" since the manufacturer didn't test it on any inverts, and I'm wondering if maybe it could be a similar situation here. I'm having a very very hard time finding information about gentian violet's use in fishkeeping at all though, it seems currently extremely uncommon. What I will say though is that I'm on day 2 of treating my tetras with it, and the bladder snails seem just fine -- in fact today I noticed what looked to be a bladder snail that appeared to be newly hatched (because of its size) that I hadn't seen before that was zipping around the tank without issue. But obviously, shrimp are not snails, and bladder snails are also notoriously hardy little guys, so what I'm seeing right now could easily be totally inapplicable to cherry shrimp. It might even be inapplicable to other species of snails, for all I know. Has anyone else here ever used anything that contains gentian violet in a tank that actually does contain shrimp? Were they okay, or should I make sure to not use it once shrimp are added?

      One interesting thing he mentioned was "Bacteria pressure", which I guess just means number of bacteria around.  Yet I see all these other videos from shrimpkeepers bragging about how much bacteria their filtering system holds. Also interesting is no mention of using anti-biotics to treat bacterial infection.  I think that has fallen out of favor recently.
