      Hi, I am doing a project for my college course:
      How does temperature affect the number of fry a cherry shrimp produces?
      I have setup a small 18L nano tank and it’s currently cycling. When ready, I am planning on taking 1 male and 1 female cherry shrimp from my main shrimp tank and putting them in the new tank. and waiting until I see eggs. I will then remove the male and when the eggs have hatched, or when the babies are big enough to see, I will count them. 
      I will then repeat this with different temperatures.
      it seems like it will all work in theory and I have 1 year to do this so time is not an issue. The only issue I see is that I’m unsure how Will I accurately count the fry? 
      This is vital for my project and if anybody has ideas I would greatly appreciate it. 
      cheers :)

      New to shrimp keeping and trying my best! I think water parameters are OK, have live plants, filter, light on a timer, heater and RO water with weekly water changes and testing. Fed 2x a week 1 ball per shrimp of 'shrimp enhancer ' supplement (calcium and magnesium in etc) but 2 shrimpies have an issue... sort of discoloured/opaque orangey bit on their backs.
      Can't find anything similar in pics so hoping for diagnosis and way to fix please!!
      ps. Apologies for crap picture, phone won't focus!

      I've had 3 cherry shrimp die in the last 2 weeks and can't seem to pin point the issue. For context I had 13 cherry shrimp in a planted 10 gallon with 7 Celestial Pearl Danios. I found the first dead shrimp one afternoon, half eaten by the CPDs. Now about 4-5 months back I had witnessed my CPDs attack and kill a small male cherry shrimp. So my initial thoughts were that the CPDs had done it again, which is odd in itself as they have been fine together for many months. So a week later I found another dead cherry but this time it seemed to have died within the last hour of me spotting it and it hadn't been touched by the CPDs (it was at night, so the CPDs were sleeping). This got me thinking that perhaps, the first Shrimp had died due to something else and then picked off by the CPDs. About 5 days later to today, I found the 3rd dead shrimp again already half eaten by the CPDs, this one was a large adult female. Now on top of all this, I have also had 5 of 6 shrimplets in a hang-on breeder box die. The shrimplets were the first to go and which I think makes sense if it was something to do with the tank environment as they would've been more sensitive. I initially thought I wasn't feeding the shrimplets enough or that it was because I wasn't rinsing the baby brine shrimp I was feeding to the CPD fry. Now that the adults are dying too, i dont think it is a coincidence nor do I think its my CPDs that are the issue.

      My speculation is that they are having a molting issues. Now the dead shrimp I found whole had a white line across its back and a cloudy white underbelly, which I took to indicate a molting issue. The shrimplets seem to be having a molting issues too, although the 1 remaining shrimplet molted successfully, and many of the adults did too judging by the many molts scattered about the tank. However, I tested my GH and KH and got 6 and 4 respectively, which I believe is fine from what I've googled. Also I figured if there was an issue with a lack of calcium/minerals could it mean that those that successfully molted could still suffer from a weaker exoskeleton and thus be more vulnerable to the CPDs?
      Another possibility I thought was muscular necrosis, as the half eaten shrimp I found today had a cloudy white underbelly too and from memory the others all did  (not 100% sure) but I had always thought that was just something that happens when a shrimp dies. I'll attach photos to see what you all think.
      I've also considered that perhaps i'm not feeding them enough/well but my previous attempts at feeding them blanched veggies have been unfruitful, they dont swarm the veggies or really touch it (i've tried sweet potato, zucchini, carrots and broccoli). They dont go crazy for the shrimp algae wafers or the hikari shrimp pellets  either but I chuck it in the tank once a week just in case but I assume there's enough algae/biofilm for them. 
      I'm thinking of getting a mineral/calcium supplement for the water but not sure if thats a good idea if my gh/kh is already fine. 
      CPDs are all fine and healthy. 

      Anyways here are my parameters:

      Ammonia - 0
      Nitrite - 0
      Nitrate - 0
      PH - 8.0
      GH - 6
      KH - 4
      TDS - don't know. I've seen mentions of TDS but not quite sure how important it is with cherry shrimp. Do you think I should get a TDS meter?
      Temp - 26C
      Water change - 25% once a week with dechlorinated tap water.

      Would love to hear some of your thoughts.
      Top Left: latest death with white underside (fuzziness?) visible. Top Right: Second death with the white line across the back visible as well as a white potruding underbelly.
      Bottom Left: Just a picture of an alive shrimp in the tank, to see if anyone can see anything wrong. Are those brownish discoloration an issue?
      Bottom Right: Another live shrimp can also see a white underbelly which I thought was normal?

      Hi! I've just started a YouTube channel, and my first video is of my 8 month old no filter Jarrarium. Nothing in-depth, more about the aesthetics...and the cherry shrimp 🙂
      Subscribe if you like it, as I'll be posting more videos of other tanks, updates on tanks etc.
      Take a look and let me know what you think! Would be good to get some knowledgeable opinions! Thanks🙂

      Hi all. I'm a newbie. I'm keeping a 90 litre tank with cherry shrimp and daphnia together. I'm feeding them spirulina and commercial shrimp food.
       Does anyone know what else I should be feeding them? Anyone else have this mix of tankmates?

      I have duckweed in one tank and I have tried several times to get rid of it but it keeps re-appering so I would recommend you avoid that. TheCaridina shrimp are a lot more difficult to keep so do lots of research before you start dwn that route, and be prepared for the fact it may not work even with the best attention and parameters/ Simon

      Thanks for updating us, whether good or bad it is nice to know what happens! I am delighted to here you are having some success, thats one up on my attempt!!!! I have just fished out about a dozen wild type cherry shrimp (I'm a bit over-run with them) and plan to put them in the old TB shrimp tank later just to see what happens. In theory the water is not right for cherry shrimp, and as the shrimp are brown/clear and the tank is very drab and brown they will be difficut to see anyway. Plus, the fish may eat them? Simon

      To put a final update on this thread: There was initially a batch of babies born in Feb 2020 consisting bkk and blue bolts.  They all grew up lively for the first few months, but from about month 7 til now, the BKK have been dying off one per several weeks with short antennae syndrome.  A whole tank dose of Minocycline did not save them or prevent new disease.  They never got larger than juvie size even after a year.  There is only one survivor BKK who grew up to full size and is still doing well now.  All the BB survived and seem to be doing well.  One BKK, born in July 2020 got evacuated to the Amano tank and is doing well, although also never grew up past juvie size.  I'll see what happens to that guy over the next few months.  I'm starting to think that RWP X BB (their parents) results in healthy blue bolts and genetically defective BKK.

      Thank you Simon!! L Bretz does ship to the lower USA so that's exciting. He has a ton of neos! I may add another blue velvet or 2. Aquahun's website is currently down so I wasn't able to check them out. Hope they're doing ok. Flip Aquatics by far has the best caridina selection.  We definitely keep the AC running, and always keep it about 68-70 room temp so that shouldn't be a problem. Right now here in the mountains it's in the 30s or less (we may get snow this week) but I haven't had to use the heater I bought. It's just an expensive algae collector at this point.  Just in case anyone else is looking, here are other breeders who ship in/to the US that I found: The Shrimp Farm Planet Inverts Elite Inverts AZ Gardens Lucky Aquatics Shrimp Envy Joe's Shrimp Shack  Shrimpery & Aquatics  So Shrimp

      Thank you so much, Simon!! I think I just spotted the 5th and newly hatched teeny tiny Malaysian Trumpet Snail in my tank this week. They are a Godsend honestly, because they dive down into the substrate and get every little piece of food, and there is plenty for them even after suctioning the substrate.  I had to start feeding every other day based on the frenzy, I think they have consumed most of the biofilm. My filter sponge was thick with algae and it looks nearly brand new. I have a ton of food and botanicals coming next week, til then it will have to be a tricky dance on the line of overfeeding.  I believe any freshwater shrimp would be a good meal for Tortuga the turtle. I've been able to give him fresh plants (except duckweed, I'm just not going there as I read it's a plague), fresh fish, fresh mealworms, and shrimp are really the only fresh food missing. I'll wait until I have over 20 to add to his tank, so hopefully he won't eat them all and they can propagate. I have mollies and platys in their now, the guppies never last long enough to breed. And a bn pleco but it's just a baby so it won't be eaten. Those little suckers move fast when they're babies!! I really shot myself in the foot though, since I now have a 10g and am looking at galaxy pintos. I am head over heels for shrimp!! It's super addictive. I will be asking a ton of questions the next couple months while that tank cycles. Sorry in advance. 😁
