fishmosy posted a topic in Field Trips and Meet UpsThere have been a few rumblings from Bob, Kiz and I about a new shrimp to the hobby, and possibly a new shrimp to science , which for the moment we will call Caridina sp. 'Malanda'. Thanks to Kiz for putting up some excellent pics of the shrimp themselves, which can be found here: Having kept both the Caridina sp. Malanda and the shrimp collected from Barney Springs (another possibly unidentified shrimp which we are calling Caridina sp. "Barney Springs", also rare in the hobby), they are quite similar in size, shape and colour and, in my opinion, could likely be the same species. These are currently with Ura for taxonomy so we will have some more info on taxonomy soon. Thanks @Ura. Anyway this is a report from where the shrimp were found (May, 2015). Water parameters were: TDS: 17 pH: 7.4 - Water sample was taken from within the riffles which would tend to cause CO2 to gas off and therefore boost pH. Temperature: 19*C KH: < 10 ppm GH: < 20 ppm Short video - excuse the rainy conditions We found the shrimp only in one specific location - just upstream of where Bob is standing, in the long grass at the edge of the stream. We sampled further upstream, across the other side of the creek and downstream, and found none, including in areas where the grass was growing in a similar manner to where we did find them. This is just a shot from further upstream, around the corner from the above shot. The creekbed within the riffles was rock, mostly covered in algae and some silt. there were no shrimp in this area. The shrimp were found hard in against the bank, right at the interface between the water, the bank and the grass hanging into the water. The shrimp were clearly coloured by sex - females were reddish, males blue. Note the large eggs for this species = easy to breed. Male - Top Female - Bottom We also found a species of rainbowfish in the eddies at the base of the riffles, a species of gudgeon, some sponges growing on the bedrock in the riffles and some macros (Macrobrachium sp.). None were in the same habitat as the Malanda shrimp. This macro had a parasite attached - nasty!
Recently I was lucky to get some specimens of an undescribed species of Australian native Caridina from "Northboy" Bob. Thanks Bob for the opportunity. I don't think many people are keeping these at this point but I hope that will change as they settle into captivity over the hopeful coming generations. Anyone with these shrimp is most welcome to post their pics or experiences here if they wish. This Malanda species is quite a heavily pigmented shrimp with a tendency for some individuals to have orange-red colours and others blue-greens. It seems that large females are at the blue end but I have a smaller, saddled individual that is currently orange so the difference seems not to be strictly sexual. Bob sent down a couple of berried females and from these I have juvies in the tank. The're all quite orange. Sorry for the poor quality, it's a tight crop and the best I could get at the time. Here's a couple more where you can see a bit of the bluish colour on the females. A hint of the pale bands on the abdominal segments are also visible in these and the first shot. It's quite a lovely species of shrimp with some nice potential to colour up much more.
