      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?

      It is important that we as a community are responsible as hobbyists. Recent threats include the white spot virus that has been found in prawns in Queensland and the possibility that the crayfish plague has been introduced to our country via exotic crays from North America that might host this fungus and that have immunity to it. For example entire crayfish populations in Europe have been decimated by this disease because only the North American crays have immunity.
      It is well known that many in Australia keep and breed exotic shrimps and other creatures and in most cases this is not problematic but there are exceptions and so it is necessary that we have a handy resource on the forum that discusses this topic and provides relevant links. Australia has very strict quarantine laws; although we are allowed to keep and breed a number of different shrimps in Australia the importation of shrimp species not in the "suitable specimens for import" is extremely illegal and if you are caught you will almost certainly be handed a jail sentence.
      Local fish shops will often freely take any unwanted animals (even sick ones) and there are always plenty of other hobbyists who will jump at the chance to take them as well.
      Below are some simple rules that are universally applicable -
      ? Do not release any fish or invertebrate from your aquarium to nature regardless of whether it is native to the area or came from that exact place; this is because they may have acquired a disease or parasite in your aquarium/pond and you could do much more harm than good. ? Do not allow any of your aquarium water or other contents to enter stormwater drains or go anywhere that might find its' way into a body of water e.g. creek or lake etc. The Australian government advice is to dispose of your water down the sink/toilet. ? Do not bring exotic animals into the country unless they are on the approved specimens list (link is below). ? Do not collect wild specimens unless you have checked first that you are allowed to do so. ? Do humanely euthanise your animals if/when necessary. (link is at the end of the article). ? Do enjoy keeping aquariums and treat your animals and our natural environment with the respect they deserve. Below are links to lists of noxious species and guides at a state and national level as well as links to RSPCA instructions for humane euthanisation

      So I recently looked at my tank and saw that one of my Crystal Red Shrimp has a weird deformity on her head. All of the other shrimp have been doing fine. I'm worried it may be the water parameters at my college in Florida. I don't know what kind Ph, Kh, or hardness I'm getting right now. I did recently see a new red crystal baby so some of them must be doing decent enough. Any ideas?

      Tried doing a search, came across people mentioning a cure, but did not see recommended guidelines. Just wondering if I might be missing any possible treatments?
       
      So far, I've seen people use...
      Tank Blackout Salt Baths/Salted Aquarium Paraguard Malachite Green/Formalin Products (Ick Attack, Maracyn 2, JBL Fungol, Sera Mycopur..) EM Erythromycin (heard of it) Kordon Herbal Ich Attack Personalized Treatment Plan Herbal Treatments (heard of it) ???  
      I don't have any shrimp who are infected, so I'm not asking for myself. I did have one shrimp that had the infection and was quarantined. Never made it out of quarantine, unfortunately. Someone else has at least 12 infected shrimp and they are trying products by Fritz (Mardel) to attempt a cure.
      The best treatment I've heard of is a combination of malachite green (copper) and formalin (formaldehyde), which is not recommended for inverts. Formaldehyde may no longer be available after this year (at least not on the shelves), so other treatment options would be great!

      You are indeed correct in that I didn't see a cycle as such, I only had nitrates of 25 to start (cooked prawn) and that dropped but also as you say the PH was very low, below 6 so a proper cycle may not have happened - well spotted, I had forgotten about that. I set the tank up in June so if it isn't cycled by now though I guess it never will be? Incidentally I have only got the Ph up to 6 (recently) by putting a bit of the old rock back temporarily, and possibly that caused the tank to cycle or something??? I have thus far got 4L of RO water and hope to get more done so I can do a approx 50% water change at the weekend. You make a lot of valid points and thanks for giving me more to go on, maybe the plants aren't as green in this tank because of the different parameters and the substrate isn't as bad as it appears? The other tanks have Ph 7.5 so quite different! I like your point one and that seems to be how most people think in the modern world, but I am 100% sure it is my fault one way or other, I am old school! I am however physically restricted so it isn't anything I can do anything about! Got friends coming on sunday so if I get the water ready they can lug the buckets of water around................. I will get some rubber gloves anyway as that means I can rule that out, and give me peace of mind for the future that I won't accidentally contaminate the water by mistake? I have been using a lot of cleaning products (scrubbing floors) around xmas which makes me think I may have contaminated the tank without realising??? Simon

      Just to update that I went back to my normal, very low dose of fertilizer, but the Ludwigia are still dying, from the bottom up.  The tips are green and growing, but the bottom parts are rotting away.  So far, I can only think of two possible reasons: 1) I have been feeding my shrimp less, so maybe they aren't making enough ammonia and nitrates for the plants 2) About 2 months ago, I changed the lighting so that it was a complete blackout at night and only 7 hours of medium light a day.  This did a great job of getting rid of algae that was growing on the plants, but maybe now I need more light again?
    • beanbag
      My first choice is still to blame the substrate.  The reason is that it becomes "not your fault". But secondly, I might blame the biological ecosystem.  I don't think you ever "proved" that you have a cycled tank, in the standard sense that it can remove 1ppm of ammonia per day.  And in my own experience, if you have a low pH (like under 6), it could take forever to cycle a tank.  (I wasted about 1-2 months on this)  It's possible that you have a case where you don't have much nitrifying bacteria, but rather the plants are the one consuming the ammonia.  And maybe that is ok, I dunno. Thirdly, I am not a big fan of using dead meat or fish food to cycle a tank, because not only does it create ammonia, but it also creates water pollution.  Again, the standard thing to do is a 95% water change before adding animals to get all the nitrates and pollution products out. In any case, if I were in your position, I would do the standard "it can't hurt" things of: 25% water change per week with remineralized water A low dose of Prime anyway, in case there is a very small amount of ammonia Add some nitrifying bacteria in a bottle, or keep adding some bacteria from other tanks (as long as they have a similar pH) Maybe add some probiotic bacteria like Dr Tim's Eco balance.  I have no idea if this will actually help, but it probably won't hurt.

      I won't be using the gloves for long in the tank, quick front glass clean and then the sponges so they won't be in the tank long, but I will rinse them a couple of times and dry them off before I first use them! I don't have any spare JBL soil to do that experiment, but I have used that in the other tanks and all has gone soooo much better, though there is more prep required with it but that is a small price to pay for the rewards. Shrimpking is by dennerle so I don't for a second think that can be the actual problem killing the shrimps! But the other tanks with JBL are so lush I would definitely use that in future!  Simon 
    • sdlTBfanUK
      We are having similar issues, though I have only seen 1 dead shrimp but they are disappearing! I am only giving it one more go as we are half way through winter here so at least if I go carefully and manage to keep them alive they will at least start breeding as yours are. That was when mine exploded with shrimps in the previous case and losing a few adults then doesn't matter quite so much? I tend to believe the babies are tougher because they have always lived in that environment anyway and not been as stressed as purchased shrimps. You are not alone in getting frustrated with this type of problem, at least if you can pinpoint what went wrong you can correct it? I have done pretty much exactly what I did last time so am really baffled and clutching at straws now! Simon
