      Hi - I'm wondering if anyone can explain what went wrong with my shrimp tank!
      Although the parameters for ammonia, nitrate, nitrite were good in my small tank, the pH was high (8.2). This remained constant over a couple of months, so I thought it was ok. GH & KH were 6.
      Then a couple of weeks ago the red nose shrimp, them this week the cherry shrimp and finally the nerite snails, died. I couldn't figure out the problem. Then today I emptied the tank. It was up on a bookshelf so normally I can't smell the water. Today when I siphoned it out I could smell a very strong chemical smell and the taste (a quick sampling when I siphoned), was tangy. Not like the earthy smell and neutral taste of the other shrimp tank I have. 
      Any ideas what it could have been?

      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!

      Hello,

      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.
      Cheers!

      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🙂

      Also, I forgot to say and ask. Very few of my neos are 1 color. Most have a clear area where organs are, then circled by its color. Let me share a picture.  This shrimp seems like it's black but head area is clear. Most of my blue neos were like that.  Now this one is one of the few that grew up 1 colored, and I have no idea what freaking color it is. I didn't buy it, so I'm sure it's one of my first babies from last September/October. But parents were both blue neos, and it doesn't have a clear area where you can see organs. Is that normal?

      Thank you for all the help. I believe the issue was a bacteria. Deaths have stopped so far. Shrimps are very active, they keep molting and there's still 1 berried female. I keep doing water changes until it cycles, and half the tank doesn't have the fuzzy white thing anymore. The other part does still.

      I haven't been able to find an ammonia test kit so maybe that was my problem but I woke up to no dead shrimp. Before I do a water change I want to make sure my water I have is correct with water parameters and GH and KH  especially. I did cycle my tank and it should be fully cycled by now.    Thank you all!

      Sorry to hear you lost some shrimps! How big is your tank and how long has it been running? Did you do the 'cycle'? When doing a water change you should drip the new water into the tank. That will illiminate the temperature difference problem and any difference in parameters between the two waters. When acclimating new shrimps you should drip acclimate them as long as you can, the longer you do that the better chance they have of survival. You will need to match the water temperature to that of the tank by floating the container with the shrimp in the tank once you have stopped dripping, before adding the shrimp to the tank! The parameters you have I would think are acceptable so I would stick with tap water if that is what you are using, for now. RO water is ideal but you will then need to buy GH/KH+ to add the minerals. As I say, I would hold off using RO/distilled water for now until we can pin point the problem. If your water has a green tint to it that may be an algae bloom? A white tint is usually a bacteria bloom and I have only seen that whilst a tank is 'cycling'. I think an algae bloom will mean there is less oxygen in the water as the algae absorbs it?????? Overfeedinng is very common. It will depend upon the size of the tank and how long it has been running etc. With only a few shrimp there may actually be no need to feed additional to the natural biofilm of the tank. As shrimps are feeding all day on biofilm it is usually better to see additional food as just a treat and feed very sparingly. Overfeeding with shrimps doesn't usually mean that the shrimps over eat, it usually means  too much uneaten food polutes the water and if you have green tinted water, algae bloom, that may be why? There usually comes a time, if you are lucky, that there are too many shrimps in the tank for the biofilm to sustain on its own, so as the population grows feeding may become more necessary. Shrimp don't usually hide unless they are new to the tank or there are fish etc (even then they will usually adapt to them) or as JayC says, their is something wrong with the water quality?  Simon

      Sorry... this was meant to be partially sarcastic. I mean it's a bit sad but I don't really mind all too much. Yeah they're like that, with those big mouths.
