  1. Hey folks! This thread is intended as a documentation (and space to ask questions of course) of @Frosty and my venture into caridina shrimp. We’re starting off this weekend with 15-20 mischling shrimp (tibee x CBS), and maybe in a couple months if everything is going well we can add some TTS or KK or pandas or something. The tank is a 4ft, with inert gravel and rocks, lots of moss, Java fern (crested and regular) and assorted crypts, and a couple big pieces of driftwood. Current parameters are the following (please advise us if you think we should fix anything): 22°, 6.8 pH (we might try ageing our water change water with peat moss, so with a couple water changes we’ll bring this down to 6.4-6.6), 3GH, 2KH, and 0 nitrates, nitrites and ammonia. We’re thinking maybe to make it more interesting to the average onlooker, we might add a small school of chilli rasboras, but that’s hopefully going to be it for fish. The tank is in direct sunlight, so there’s a possibility we’ll need ottos at some stage. I’ll update later with photos and our plans. Please let me know if you’ve got any advice! Cheers!
  2. Gading of Caridina logemanni, Caridina mariae and Taiwan Bee Shrimp has been a hot topic recently on various groups and there hasn't been a consistent application of grading across these shrimp. There is a lot of hearsay but nothing documented anywhere. As a result, to ensure we maintain a consistent approach to grading here and on our Facebook group, I'm putting forward draft gradings for feedback from the SKF community. Grading TableGradeDescriptionExamplesHigh> 90% total body coverage of the identifying colour the shrimp looks crisp and perfect to the naked eye may still have some small imperfections under magnification. Medium70% - 90% total body coverage of the identifying colour the shrimp is not as crisp also has some slight imperfections in the overall appearance with the naked eye. Low35% - 70% total body coverage of the identifying colour the shrimp has the appearance of being patchy and imperfect the overall appearance with the naked eye is poor. CullThe shrimp has reached a point that it is barely recognisable as belonging to the intended group also genetic and physical deformities etc that mean the shrimp should be removed from the general population. Championship: The shrimp must appear perfect and under magnification show no imperfections or blemishes. The perfect example with full body coverage of colour and pattern for the given variant. If anyone has examples that we can use in the final grading information, please attach your watermarked images here. Also, should the quality of the offspring be representative (or better) of the parents grade?
  3. Hey everyone, I was recently (meaning today) given the opportunity to set up a breeding tank for some native inverts (or some harder to breed fish I guess, but I want to go for shrimp) in a fishroom I help out in. I've been trying to decide what native shrimp I want to try breeding, but then I remembered that it's not as simple as exotics. Can I get some input from the 'experts' (@Grubs, @NoGi, @Baccus, @fishmosy, @jayc of course, I know most of you aren't very active anymore, but I would appreciate your help if you see this message) on what native invert you guys think is easiest to breed (for a semi-noob who hasn't kept natives before). I can set it up as brackish I think, we have an archer fish tank there and are setting up a saltwater as well so should have access to those tools and materials. Cheers!

    New Tangerine Tigers!

    Exciting news: I just purchased 15 tangerine tiger shrimp from a local breeder, in exchange for some of my abundance of endler fry. I’m starting the drip acclimation now, along with my other two tts males who I’m moving from my larger tank. I’ll add some photos down below once they’re in the tank. Will acclimate another hour and a half probably, and feed the fish a bit extra before they go in for safety. There’s heaps of good hiding places in this tank, and I can’t wait to see the shrimp utilising them (or hopefully not even see them)! Will update soon. Cheers, Crabby

    Shrimp ID???

    Short info... I'm in USA I got these from a pet store They were being sold as something they clearly are not Larger than cherry shrimp, smaller than amanos (as in, at best, females get to the size of an adult male amano, but not female from what little I can see) *NOT* Neocaridina *LARVAL STAGE of 1+ weeks* I've been told these are 4 different species (well, 6 or 7 if we count the ones I know aren't true) so I'm looking for some second opinions on what they might be... what I do know is that after a week or so, the larvae have not transformed into miniature adults. These are some of the more colorful shrimp, some have less colors but they all mainly share the dark "band" midway down their tail, except males which may appear very bland. (I'm not entirely sure it's only one species of shrimp...) Female Male And a 5+ day old larvae/zoe (younger zoe don't show as much color - more clear) And just to throw a curve ball in there... here's another shrimp that was mixed in with the type above! (clear shrimp, appears more yellow than he really is... this is also a relatively small shrimp, hardly any bigger than an adult cherry shrimp. He's the only one...)
  6. Hey guys, I’m really wanting to get freshwater crabs, and the only ones I’ve found are A. Lacustris and A. Laevis. I can only put them in a 110 L community tank for now, but may have another option in the future. The tank is stocked with a large school of ember tetras, some rocket killies, some endlers, some tangerine tiger shrimp, and a pair of apistogrammas. Rare aqua advised that A. Lacustris would likely be eaten by the apistos, so the obvious choice would be A. Laevis, because they’re larger... right? But I’m worried that they might predate upon my shrimp, so wanted to hear some advice and opinions from more people with experience keeping these crabs. Cheers!

    Hello Everybody

    Hello Everybody, My name is Kenny, and i'm from Belgium. Since a year or so i am keeping Caridina species. I love the little animals, and i love watchin them work their way around the aquarium.
  9. Hi I am new with caridinas and I want to make a shrimp rack to keep them. It would have four shelves and in each one of them would fit an aquarium of 82.5x29.5x15'5 and I want to divide it into two or three or four partitions that water communicate between them somehow but I do not know how to do it. Some suggestions to make the dives so that water is shared among all and that the young can not pass from one to another. I added an image where you can see how the possible divisions would be interesting to divide it into four partitions but every division is very small and I want them to be communicated to compensate that they are small aquariums and achieve a greater stability of water parameters altogether all of them. Sorry for my English I tried to do my best because I am from Spain and I am not English speaking. Greetings and thanks.
  10. There 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!
  11. This article was written by Werner Klotz, the scientist who authored the recent description of CRS and tigers from Southern China. I have written permission from the author to translate and reproduce the article here. I thank the author for permission to post this information here. I apologise in advance if my translation differs substantially from the original. The original article can be found (in german) here: http://www.wirbellose.de/klotz/neocaridina.html Caridina or Neocaridina? © Werner Klotz Many of our dwarf shrimp do not have a scientific name and are instead referred to as Caridina sp. or Neocaridina sp.. In aquarists literature - (I believe the author is referring to online forums, magazines, ect., but not scientific literature), one occasionally finds the idea that species with large eggs and direct-developing larvae (larvae that essentially hatch as mini adults) belong to the genus Neocaridina, whilst species that have planktonic larvae and small larvae belong to the genus Caridina. This is incorrect. The type of larval development has nothing to do with which shrimp belong in which genus. In 1938, the genus Neocaridina was divided from the genus Caridina by Japanese scientists (1). The separation of the two genera was based on the inner branch (Endopod, En) of the first swimming leg pair of male animals. In species of the genus Neocaridina, this has a pear-shaped, distally broadened shape. The internal appendix (ai), a small appendage on the inside of the endopod, is found (if present) always in the basal region (bottom) of the endopods (Figure 1). Figure 1 In the species of the genus Caridina, the endopod has an elongated, sheet-like, distal, narrow shape. An internal appendix is found (if present) near the distal end (the end furthest away) of the endopods (Figure 2). Figure 2 Another thing which differentiates Neocaridina and Caridina can be found in females as well. On the first maxilliped (the legs around the mouth that assist in feeding), many (but not all) species of the genus Caridina have an exopodite (a finger like spur). This is absent for species in the genus Neocaridina (Figure 3 & 4 - arrow). It should be noted that the separation of the genus Neocaridina has been opposed by some taxonomists. In their opinion, the term Neocaridina is just a synonym for Caridina (2). The genus Neocaridina was recently reviewed by Cai (3) who confirmed the genus as being separate to Caridina.

  12. Not a very sophisticated tank - just 3 granite pebbles on a thin layer of inert sand. Eucalypt leaves and sticks (aged in the bottom of a pond) with some Indian Almond and Mulberry added for variety. ~ 30% rainwater changes 1-2x per week (water at room temperature from supply in fishroom). Lighting is strong because the tank is sharing the light with some algae cultures = green rocks and side walls. Tank is small 45cm tank (~20 litres) oriented end-on. Just waiting to move some fish around and will upgrade them to a 40l tank. Room temp is ~23C GH<1 KH<1. The light is over the front part of the tank. most of the zebras hang out more on the filter sponges or under leaves during the day but always a few visible. Seems to be more action at night. I've noticed lots of activity when adding fresh rainwater - they really seem to like the current and fresh water. This is perhaps not surprising given they are found in flowing streams. There are a few juveniles that arrived as eggs on berried females - but no breeding evident in this tank yet.

  14. Hi, does anyone have any information on Australian Zebra Shrimp? I got a free one in a fish order and don't know anything about their care or size or anything! ? It'd an awesome looking shrimp. I have popped her in with my cherry shrimp, hope that's ok?!

    Caridina White Backed

    Hi All, Posting after a long time - Presenting One native shrimp of India - Caridina Sp. White Backed. Some of us call it as Indian Bee also. The shrimp generally comes in 2 color - orange-mud color and also blue color. And some times the rare black ones also been caught, but they are really rare. I have separated the orange and blue and will breed them separately to see what is the off-spring color I am getting. Providing 2 images as of now, and the images are from fb so some sharpness already have been lost -
  17. Hi everyone, I'd love to get some Caridina sp WA 4 - North Australian Chameleon shrimp for my aquarium but I'm having trouble finding people who sell them in WA. I have spoken to fisheries and they are happy for people to keep them as they are WA natives. Does anyone have any ideas where I might be able to get some? Cheers

    Caridina zebra pics

    I was one of the lucky people who set up a tank for our amazing native zebra shrimp recently, thanks to our forum hero Northboy who made some available. These are an amazing little shrimp that look very different to a CBS, despite the conflicting perception often voiced by those who haven't seen one yet. They have a reputation for being very difficult to keep going in captivity. Like anyone, I spent a great deal of time reading about the habitat and water parameters, previous experiences of those who have kept them and so on. Unfortunately there's little to read and no long-term success stories. You just have to hope for the best really. The tank was running for some time before I added the shrimp so had a healthy biofilm going and plenty of brown diatoms. I added some leaves from an outdoor container which had collected rainwater and autumn leaves over the last few months. I added a mixture of rainwater and tapwater which is pretty normal for me, both are processed through a carbon filter before reaching my tanks anyway. The tank has a thin layer, perhaps 3mm of fine white silica sand as a substrate and decaying leaves as the only real structure. I have one inert river rock in the tank, positioned to break the return from a HOB filter. Probably my least favorite style of filter yet I'm running 2 on this tank plus an air stone. The temperature is 22 +/- 1 degree C, pH essentially neutral, GH an KH undetectable, EC around 60uS (about 30ppm TDS). I have never felt any need to use RO water for any shrimp I keep, including Taiwan/Shadow Bees. However for these shrimp, it is just impossible to keep the TDS that low. I've already grabbed 20L of RO from a mate (thanks shrimply!) because the EC had gotten to around mid 70s (uS) and I felt that the shrimp were less happy then. I'll be buying an RO unit, the ability to remineralise with correct salts from virtually 0 will be a real advantage with these - as Fishmosy is already doing with his. The zebras are constantly picking away at the biofilm layer but do not seem to take any offered food. This is in contrast to what others have reported - snowflake, Boss Shrimp Crack, Mulberry leaves and Dandelion leaves have all been completely ignored in my tank. I can't explain this as yet - do they prefer biofilm and only accept other food when it's in short supply? Perhaps snails are taking the food in other tanks and actually nobody's zebras take prepared foods? There's surely other alternative explanations that haven't occurred to me yet. One thing is certain, mine are doing ok with just biofilm - the female in the pic above is clearly developing a saddle. In the shot of 2 shrimp above you can clearly see a hydra too, so it seems like they're doing ok without added food too. BTW I have been removing the leaves just before they really start to disintegrate to help keep the water clean. When the shrimp were sent down there was a couple of berried females as well as some small shrimp. These are growing well but the nice surprise was to find a new one the other day. I would say it's about a week or so old, definitely from one of the berried females and born in my tank: I don't know if there's more that made it - I saw this shrimp one day for about an hour and then it was gone. I perform a daily head count on the tank and while they're mostly out and I count to within 10% of the known population, there's plenty of places to hide in the leaves. They're also quite well camouflaged even on a plain white sand.

    Caridina sp. Malanda

    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.
