      Hey Guys, I'm hoping someone will be able to help me out. I am a first-time shrimp owner. Four days ago I came home to find that one of my poor ghost shrimp ladies has this weird blue/white moldy looking coloration on her head, primarily on her rostum. She is otherwise still moving around, eating normally, and not hiding. I've done some internet sleuthing (I was leaning towards possible vorticella or bacterial infection), but haven't yet found anything that fits the description and was hoping someone may have run into this before.
      Link to pictures
      Tank:
      - 5 gallon, long. Fully cycled, 2.5 months old
      - Houses 4 ghost shrimp (all female), 1 betta, and approx 9 baby shrimp in a breeding net.
      - Filter (sponge) + Heater.
      Shrimp have been in the tank with no problem for about a month
      Water Params (as of November 8, 2020)
      - PH 8.2
      - Amm: 0-0.25
      - NI: 0
      - NA: 5 ppm
      - Temp: 78

      Treatment so far:
      Day 1: 50% WC, and dosed 6ml of 3% hydrogen peroxide (with filter removed).
      Day 2: Did the same hydrogen treatment, with no change in the shrimp.
      Day 3: Removed all of the plants from tank and dosed 4.5tbsp aquarium salt, with plans to do a PWC later in the week to slowly phase out the salt.
      Day 4: 60 second salt dip (ratio of 1tbsp/cup) for all my shrimp and the above hydrogen peroxide treatment. I fear that whatever the white-ness is has spread to at least one other shrimp due to a noticeable color change in her legs and pleopods
      Anyone have any idea what this is? I'm not sure if I should quarantine the sick shrimp or just treat the whole tank at this point, as I'm not sure if it's contagious.
      Thank you in advance!

      When I fed my shrimps on saturday I counted 80 and yesterday all appeared well also.
      This morning all I can see is dead bodies with a reddish colour shell to the head area.............. I assume it is rust but am not certain, only going by what I have read here.

      From what I have read here it could be because the substrate was exhausted and the PH had risen to 7.5 last time I checked (though that was slowly over time)?
      I doubt there is much I can do at this stage, but I will set up the old 15L to put any ALIVE healthy looking shrimp in IF THERE ARE ANY! and close down the big tank and start again. I guess I know next time that when the PH indicates that the substrate isn't working properly to act quicker???? When does the learning finish!
      My main queries at this stage are:
      1) Is it safe to put stuff from this tank with the dead shrimps into the small tank where I will put any healthy shrimps (If there are any alive that is) or will that be a bad idea, I am thinking, water, heater, maybe a plant or 2 etc.
      2) How do I make the bad tank good now so that it won't be contaminated for the restart? Tank, filter, heater, plants, decorations etc. I will use new substrate.

      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

      Euthanisation Key Points / Summary:
      Not everyone can bring themselves to end the lives of their own animals but regardless; if you deem it necessary to end the life of any tank inhabitants and they are not a highly illegal specimen then please dp ask your local retailer first if they might be willing to try to save them for you. If this is not an option then please see below links.

      I don't know if bacteria is the cause.  It seems to be an uncommonly diagnosed problem because most shrimp articles only talk about bacteria infection as "a few shrimp die every day / week"  What can I say, a standard dose of minocycline and erythromycin didn't work to stop it, so not sure if oxytetracycline will work.
    • jayc
      Ah yes. That was the injectable form of oxytetracycline. Each mL of the injectable form contains: 100 mg oxytetracycline HCl, 5.75% w/v magnesium chloride , 6 H2O, 17% v/v water for injection, 1.3% w/v sodium formaldehyde Sulfoxylate as a preservative and q.s. with propylene glycol. Basically, it has additional compositions in it. 1000mg might have been the dose recommended for the injectable oxytetracycline, but if you have the powder form then follow the dosing rates as recommended on your bottle. Hope that clears it up a bit.     As for doxycycline and it's use to treat short antenna ... I cannot comment on whether it will be more effective than oxytetracycline or not. But if you do use it, only try one at a time. Is bacteria even been proven to be the cause of "short antenna disease"?

      14 April 2015 -  Update based on experiences of one of our SKF members. Unfortunately for this shrimpkeeper it was too late to save these shrimps, but hopefully this experience will help someone else. 250+ shrimp were lost before the bacterial infection was halted.   A vet was consulted and he eventually ended up contacting a senior lecturer of aquatic animal health at University of Adelaide school of veterinary science. He stated that bacterial infections being internal or external are almost always gram negative in aquatics and recommended using oxytetracycline at a dose rate of 1000-2000mg per 40ltr of water.   Dosing method: Oxytetracycline is available in 2 forms. Powder and injectable. The injectable form was used as it is a stronger form. This meant that we could use less to obtain the required dosage.   Dosed straight into the water column at 1000mg per 40ltr of water.
    • jayc
      What?! Can you point me to where you saw that please?   If in doubt, Always follow the directions on the bottle.
    • beanbag
      What is the recommended dosing for oxytetracycline?  The sticky thread has a mention of " 1000mg per 40ltr ", but I don't know if that refers to total amount of powder, or active ingredient percentage. I live in USA, where oxytetracycline is not as common, but I was able to obtain a bottle of powder.  On the bottle, it says [calculated out to] 75 mg / 10 gal, which is a wayyyy lower value.  Also, the manufacturer / distributor won't tell me the fraction of the power that is active ingredient vs filler. This is for a Taiwan Bee shrimp tank with pH 5.5 and Gh 5, in case that matters for the effectiveness of oxytet in these parameters. I also have doxycycline available if that is equivalent / better. It's to treat that "short antenna disease" in one of my tanks that seems to show up once every few months. I've already dosed with Maracyn 1 (erythromycin) and 2 (minocycline) and they didn't seem to work.
