Did someone say Australian native shrimp aren't as colourful as exotics?

Awesome Ben, is the blue a stress response, or do the shrimp look like that?- what type are the blue ones? Where does one find those?

The blue is likely a stress response as this video was taken not long after the shrimp were caught. The blues are Caridina serratirostris which I've taken to calling ninjas. They come from far north QLD. They are different to the similar looking shrimp from Northern Territory - which I call chameleons (currently called Caridina sp. WA4, and awaiting formal scientific description). Chameleons are more likely to be more widespread in the hobby given they are bred and sold commercially. I'm only aware of a couple of people who have the ninjas.

Gotta like that, they look great. When you say chameleons and ninjas is that because of the stripe on the back?

@fishmosy, is the serratirostris also colour-changing then like the chameleons? The photos on Google look pretty uniform in patternation, so I am just curious as to whether they will have the brown and cream colour zebra stripes as standard?

serratirostris is a colour changer - like chameleons. They do not always have the black and white stripes (although that is my favourite pattern), but can be red, blue, orange, brown and black. Also seen them go basically transparent when they are really stressed.

Just a clarification here mate, while you're calling these serratirostris they're almost certainly not that asian species but another undescribed endemic? Perhaps "aff serratirostris" or "sp QLD Ninja" would be more appropriate as a temporary name to avoid confusing readers. 

Hope you get some DNA results back soon.

Our current understanding is that it is the same species as found throughout the Pacific -based on morphology. This is not surprising given they have larvae that develop in brackish or saltwater, and should therefore be quite easily transported between islands through the Pacific. However I'm recently started a project collaborating with shrimp taxonomists in France, looking at the genetic linkages amongst this and other widespread species. Similar projects on other animals in the past have demonstrated that one widespread species can be a complex of closely related species. So it's entirely possible the Aussie ninja is a different species to those found elsewhere in the Pacific. I will keep everyone updated as the results come in.

It will be very interesting to find out the true name/ species of the QLD colour changing shrimp largely because it strikes me as strange that the Chameleon Shrimp (C. sp WA 4) are fresh water breeders while the QLD equivalent apparently does not. To my mind the NT (well the northern coastal parts at least) are closer to Asia than most of QLD is and to my mind you would think that the breeding habits would be the other way around. It seems the same is true for the Red Nosed Shrimp, with the NT species ( C.sp Gulf 1) being campable of breeding in fresh water while the QLD species ( C. gracilirostris aka Needlenose Shrimp) is not capable of this ability.

I would dearly love more morphology to be done on our "glass" shrimp because I have caught all sorts of colours ranging from plain to DAS type markings to blacks and blues with solid stripes down their backs. Sadly they never keep the colour for long once caught and then tend to look like typical glass shrimp and when trying to identify them too many people trot out the good old catch all phrase " their glass shrimp" and then wipe their hands of any more information.

As much as I like some of the overseas shrimp and bemoan the fact that there are so many I will never keep, I still believe that in Australia we are sitting on a wealth of potential aquarium shrimp that could make the rest of the world drool

your observations on the breeding habits of the shrimps are spot on - except that the ability of shrimp to breed in freshwater limits their ability to disperse. For Shrimp that have larvae that go to saltwater, the shrimp can be swept out to sea where ocean currents can potentially carry the larvae anywhere (obviously currents tend to flow in the same direction continuously, but you get my point). The second point is that there are several currents that travel to the east coast of QLD down from New Guinea and the Pacific. In comparison, the gulf of carpentaria has few currents, if any. So yes, although NT may be close to other Pacific Islands, it's actually harder for species to travel across. Hence why there are many endemic aquatic species (aka found nowhere else) in the Territory, and species on the east coast of QLD that are found through-out the Pacific.

Very true. Note that several of these names are in doubt. For example, 'indistincta' is actually 5 different species, with formal descriptions as yet unavailable (but hopefully coming soon).

There are true ninjas here in Darwin but they are too difficult to breed in captivity, that is why Aquagreen has not offered them for sale.

      Thanks for replying. I know what you mean about breeding, I started off with about 10 and was soon (couple of months) over 100, and  I am sure that would have kept going up if the tank could  have supported more??? I don't see any reason that it wouldn't work with bee shrimps if it is working so well for your cherry shrimp. Obviously the parameters are different but if you are managing to keep the cherry tanks stable I don't see why the bee would be any different, although they are a lot harder to keep! Worth a try though unless someone says otherwise? I shall certainly follow this with some interest. Simon

      Hi Simon, NO, I wasn't using a buffering substrate previously in the neo tanks, it was just some white gravel that I had laying around. It had originally been in a fish tank some years ago, so it wasn't new when I put it into the neo tank. It started to break down just because of age, and my GH, and subsequently TDS, were rising out of control. JayC talked me through a rebuild with a bare floor. It has worked so well that when I set up more neo tanks I just made them bare as well. Like I said, I wouldn't go back. The little buggers are breeding like crazy, I have a very high baby survival rate and almost no deaths. Under my particular water conditions, it works great ... for neo caridinas. Now I want to do the same with caridinas, but not sure if there's more to a buffering substrate that I don't know about. Hopefully someone out there will be able to help me (and you) with the answers :)  
    • sdlTBfanUK
      A very good question and one I will follow with much interest as I had a similar question a year ago in that would I need to replace the substrate when it stopped buffering with my Taiwan bee tank if all the water I use has the right parameters. Unfortunately I don't know the answer in my case as my heater stuck on and killed all my shrimps off so I am starting again, though I still wonder about the same issue, though I should have at least a year before the new substrate stops buffering.  A lot of big breeding companies that have hundreds or thousands of shrimp (cherry and bee) in each tank (big tanks admittedly) use bare tanks (for obvious conveniences) so I am guessing it will be ok! Hopefully someone who has done it may get back to this thread, but otherwise I would give it a go with a few, especially if you have a spare small tank etc and see how it goes? If you used buffering substrate before but were using RO mineralised water of ideal PH did you have a problem once the substrate lost its buffering ability? I am/was hoping that the substrate buffering wasn't really needed if the water going into the tank is always around PH 5 or 6?  Simon
    • Myola
      So here's the thing. I've got 6 bare-bottom neo tanks that have been chugging along just fine for quite a while now. There are lots of babies and it's extremely rare to have any deaths, even when I add new shrimp.  I use remineralised rain water that has been filtered through an RO. I stopped using substrates in the tanks after I had ongoing issues with it breaking down, and to be honest, I wouldn't go back. Now I want to start some caridina tanks for tangerine tigers, CRS and blue bolts but want to know if I can get away with bare bottoms in them too. My RO filtered rain water comes out at pH 5, and when I add Salty Shrimp 'Bee shrimp' minerals to give me a GH of 5, the pH goes up to around 5.8. Do I really need the buffering affects of a substrate if my water is already within an acceptable range for caridinas?

      It must have been an aluminium heatsink. The Indium in Liquid metal will eat through aluminium. Only copper or nickel plated heatsinks can be used with liquid metal. It says so on the packet, at least my pack of Thermal Grizzly Conductonaut does.
