      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🙂

      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?

      Hi!
      I found today the smallest of my 6 shrimp dead and can't figure out why and am hoping for help. They seemed generally less active in the last week or two, and I have noticed that they fan their belly flaps quite a lot (though none of my shrimp are berried, at least I am pretty sure, the eggs always seem pretty obvious on photos). Is it maybe too little oxygen? 
      The dead shrimp appears completely normal to me, and I found it lying on its side in the middle of the tank, still flapping it's belly fins. I put it in a glass with tank water where aber about 15minutes it stopped moving completely, even if prodded. 
      It shouldn't be a shedding issue, as I think this shrimp has shed about 4 days ago. It's the smallest of the 6 (almost half the size of my biggest) so I figured it must be juvenile and it shouldn't be age.
      I do have some worms in there that I can't seem to get rid of, but I'm quite sure none of them are planaria. Seems to be some sort of white flat worm that usually sticks to the glass and very thin hair like ones that float around. 
      All my cherry shrimp are solid red, so I can't see if they have bacterial infection. There always seems to be one of two that are paler/mottled but as they shed I think it's that? I have a hard time keeping them apart tbh
      I did a 50% water change and removed most of the floating plants in case there wasn't enough aeration.
      My goal with making this post is to maybe find out what might have killed it/how to avoid further deaths. I'm happy for any advice!
       
      Background/setup: 
      This is my first aquarium, just as a disclaimer, so I'm gonna list...everything, not that I oversaw sth stupid.
      I got 6 cherry shrimp and 5 MTS(that have made about two dozen babies by now) approx. 5 weeks ago. The tank had been set up and running w/ plants and filter 4 weeks before that.
      It's ~25L, running a sponge filter with air pump, have some java fern and moss, wood, flourite black sand, and dwarf grass(?) and a lot of tiny floating plants on top. The light sold with the aquarium (very bright) and a desk lamp (less bright) that I use sporadically.
      They get fed JBL 'Nano Prawn' pellets (which they don't seem to be fond of) and sometimes blanched spinach/peas/lettuce (which they will fight eachother for). Would they starve themselves for not getting the beloved spinach&peas???
      Measured half an hour ago upon finding the dead shrimp:
      PH: 7.2  
      Ammonia: 0
      Nitrite: 0
      Nitrate: ~5 (now probably 2.5 as I just did a 50% water change)
      Temp: 22-24C
      I do use dechlorinator (tetra tap safe).
      I currently don't have a gh/kh test but it's on the shopping list. They have a small piece (2x2cm) of cuttle bone permanently floating around the tank, as Glasgow water is supposedly soft and between snails and shrimp i figured they'd need it.
      It has been stable like this for at least 3 weeks now, before that, week 1-2 of having the shrimp, the ph was a little lower and small amounts of ammonia/nitrite.
      From what I read this should all be fine?

      What creature are you talking about here? I can't get an idea from the photo? Simon

      Absolutely. Just continue with regular weekly water changes. No need to alter the routine, or as Simon said, add additional water changes to the routine. Unfortunately, as long as you are using tap water, the lowest pH it will get is what you have from the tap. 7.4/7.6 as you mentioned above. If it gets down to 7.4, that should make a difference to the shrimp. Especially if GH is around 4.

      Fertilised eggs are moved to the swimmerettes . Unfertilised eggs are kept internally.

      As you say, the figures are coming down but that means the TDS and GH are getting too low really for cherry shrimp so I wouldn't keep doing extra water changes over your normal routine until you have a definitive plan, stick to your weekly usual for now. Make sure new water is added sowly as well! You could continue with the tap water but would need to get some GH+ to bring the new water TDS and GH up, but thats a bit impractical if you plan to transfer to RO water soon anyway as that requires a different remineraliser. With the RO water you will need to get GH/KH+ before you can use the RO water! The RO water remineralised is the safest way to get and keep the ideal water parameters as tap water can change from different areas and at different times of the year. As JayC mentioned, you could collect rainwater in the meantime but that would still require GH/KH+ I expect otherwise the TDS and GH (and KH) will drop even lower? You will be able to check the TDS pen with the RO water as it should be 000 (or very very close) TDS. Simon
