Shrimp death & belly fanning???


BID

Recommended Posts

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?

Without a GH and KH test kit, you wouldn't know if it's needed or not. If you can buy a TDS pen, that would help as well to get the TDS measurement. 

Remove the cuttle fish bone for now, at least until you get your test GH/KH kits.

A cuttle fish bone doesn't know when to stop releasing calcium, so that will keep climbing, and it could be too much calcium in the water.

Also note that calcium doesn't get utilised as efficiently if there isn't Magnesium as well in a 4:1 ratio (Ca:Mg).

If you have Magnesium sulfate in the form of Epsom salts, then add a little, a pinch or two for a 25L tank. Just make sure it pure Epsom Salts, without fragrance or other additive that can be added for baths.

The impacts of ammonia on shrimp can only surface a week or 2 after. So this is also a possibility.

 

Report back when you get your GH/KH test kit.

@jayc 

Thanks for the advice! The bone was removed and I've been doing 3 waterchanges a week now (still no parameter changes) and have been feeding less (based on someone else's advice).  So far (toi toi toi) there have been no further deaths, but these friends are definitely unhappy and hiding, unlike before.
 
I now got a TDS pen, and GH/KH test!
Gh: 2
Kh:<1 (i couldn't figure out how to do half a drop)
 
So those are horribly low...
 
My TDS pen apparently needs configuring and I dont have the solution to do that, which i didnt know, but unconfigured it says: 37  (28 for tap water) which is also really low (assuming its anywhere near correct)
 
To make things even better, i spotted Vorticella on some, so I'm gonna get aquarium salt to fix that *sighs*
 
Do you have advice/experience with raising gh/kh?
 
(i totally overread the epsom salts until rereading your response now, i'll get on that)

Now we know your water parameters, we can adjust it.

What you need is some remineralising mix, like Salty Shrimp GH/KH+. It will have Calcium and Magnesium premixed in a powder that you add to the tank, following some instructions on the packet. So don't worry about getting epsom salts for now.

Some of out UK members might be able to chime in on where to buy some. @sdlTBfanUK, might know.

That is very low indeed. Even with it unconfigured, it will probably only be a few ppm off, tens at the most.

At last, something I know I know, the drop test kits. I do all my drop tests by half drops, easy peasey, instead of 5ml of tank water (1st line on my testtube) use double water ie 10ml (2nd line on my test tubes) so each drop is a half. You can do quarters (each drop) etc same way, ie 20ml (or fourth line on my test tubes. This works for ALL droplet kits............ hope I have explained it properly, let me know if not and I will try again.

Good luck with the rest of it hopefully someone else can help with that!

Looks like JayC and I posted at the same time. I always use

www.pro-shrimp.co.uk as they have the best range, service and prices.

  • 3 weeks later...

If GH is confirmed at 2, then TDS should be a minimum of ~35 ppm. 1 German Degree in hardness is 17.86ppm

Tap water generally runs higher though when it comes to TDS. My tap is, on average, 3 GH and 3 KH. The TDS usually ran around 56-67ish? Which honestly isn't that high!

 

If a TDS of 28 is accurate, then the GH may be around 1.5 rather than 2.

      Hi everyone,
      Im super new to keeping shrimps. I’ve had a couple of cherry shrimps for about a week now and one of them has a strange white colouring on their back it appeared overnight/this morning and I’m not sure if I should be worried.
      Thanks,
      Ben

      My yellow golden shrimp turns blueish and I immediately have it in quarantine. What is wrong with it? I also found other shrimps have something white ish on their nose/front legs that are in the same tank. I think it’s infected the whole tank including my shrimplets. Can anyone help me identify this cause? There were 5-6 dead’s in the past few days, this morning I found 3 new tangerine tigers dead and 1 orange dead but don’t know when they were died. ?

      In this video I'm going to show you a cool method of keeping two different neocaridina shrimp in one tank without mixing them. I show you how I separate small colony of yellow cherry shrimp from blue dream shrimp by using small breeding box.

      Hi new shrimp owner here. I’ve read and done lot of research. I’ve had them for only a short time before the 3 females I have became berried all at once. One is an orange and she has a full batch of yellow eggs. I have a clear, with red saddle and tail and a little yellow. She has a small 4 eggs batch (assuming because she’s new to the tank or a new mom) and then this beauty (as seen pictured. When I read about egg color they are yellow or green. Can someone tell me about these blue eggs? The male is all black.

      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?

      yes, it's the shed shells. now that I think about it, I also remember in the video the bugs were clear, and I have seen clear ones before too, a long time ago.  But these recent ones were dark colored. So I have two tanks.  In one of them, where I normally have this problem, I have been dosing antibiotics.  The short version is that most of the shadow panda and RWP shrimp have got this disease, but they haven't died either.  But they don't recover either.  They just simply stop growing and stay at a small size with stumpy short antenna.  The first shadow panda that got this problem is still alive maybe 2-3 months later. In my other tank which often doesn't have this problem also got it, but it seems to have hit harder, where both "almost adult" shadow panda suddenly got it and died within a few days.  Antibiotics didn't save them.  It's too weird - it seems like this problem comes on suddenly, with no trigger that I can think of.  (besides "the weather was warm and I ran the air conditioned".  This doesn't actually affect the water temperatures since I have a chiller, but maybe something blew into the tank?)

      Sorry for the delay, I have been searching on here and the wider web but cannot find what you are referring too! I do know which video you are talking about and remember seeing it. The video was of a shed shell rather than a live shrimp! Are you seeing them on live shrimp? From memory I don't think it was anything to worry about and I very much doubt it would discriminate between different colours of shrimp, but was probably nothing to worry about and just part of the life in aquariums, like detritus worms and other life forms. I think they were colourless in the video, if my memory is any good? Are you still getting shadow panda deaths?

      Hello folks, I remember reading about this a few years ago but for the life of me cannot find this info / thread again. Can somebody point me to a link for this info? I forgot the forum I saw it on. There was a discussion about how if you look at a shrimp molt shell under a microscope or loupe, sometimes you can see tiny "bugs" or whatever moving around inside. At that time, I think the conclusion was that maybe it was a symbiotic relationship because it even happened with healthy shrimp. But I can't remember if this occurred only in neocaridina or caridina also? I just happened to look at a shadow panda's (caridina) shell who is sick with the "shortened antenna disease" that I always complained about. There were tiny blue/black spots moving around inside.  I also looked at the molt shells of some blue bolts that don't have this problem, and there were very few, or none, spots moving around inside the molt shell. I wonder if this could be some symbiotic relationship gone wrong and is the actual (proximate) cause of the problem.  (Since antibiotics didn't really seem to work) In that case, I would need some kind of anti-parasite medication to cure the shrimps.  What are the typical internal anti-parasite medications for shrimps?

      You may end up losing this batch entirely but then you can start completely fresh and get the aquarium set up right for the next batch of shrimp! If you do any large water changes then try and add the new water slowly, either dripper or some other way. You should get yourself a TDS meter (as JayC above), they are cheap and readily available. You should always use a GH tester kit as well with shrimps, if you do the 50% water change that should halve the GH so you should get a reading after that, or if you can get a local fish store to test it for you that will give you an idea of the GH. If your water supply is as hard as it appears it may be you will need to mull over how (or even IF) you want to keep shrimps as that may mean using RO or distilled/bottled water and buying a proper shrimp specific remineraliser? That will be quite expensive but you won't then have to mess about adding crushed coral/eggshells etc, but only you can decide whether you want to do/spend that much etc? If you live somewhere that gets a lot of rain, then you can use rain water? Also, as JayC states, you need to know what you are using/adding to the water and aquarium, ie fertilizers, rocks. Unless you have very exotic plants you shouldn't need any fertilizers. Just as a note, we have come across quite a few experienced fish keeprs that have this sort of start off issues with shrimp. Shrimp are more difficult than fish, and the aquarium and water etc need to be ready and within the required parameters before getting the shrimps. Usually people jump in, get the shrimps before everything is ready/sorted. Hopefully though you will keep at it, or if this lot die you will have another go and we can help you get it sorted?

      These are all classic symptoms of shrimp moulting problems.   Again, another high GH symptom. High GH not only causes harder carapace (shell), but it also makes eggs harder. When the egg is harder the male finds it more difficult to fertilise the eggs.   That's a worry if you can't get a good GH reading because that is going to be most likely issue right now for you.   Because snails don't moult.    If you dont already have a TDS meter, I suggest getting one asap. It's another test to narrow down your water parameters, and not have to trust one test by it's own - in this case the GH test kit. I would wager your water parameter is too high in dissolved minerals - likely from the tap water source, fertiliser dosing and/or any rocks/crushed corals you might have in the tank. To remedy this, you need to start doing water changes with RO, distilled or rain water immediately. I would do a 50% water change with RO water asap. Then look for sources that increase GH in the tank and eliminate it - fertilisers, rocks, crush corals, shells.    It's difficult to save a shrimp who's carapace is already too hard, but hopefully any younger shrimps will benefit from the water change and the reduced GH.   Good luck and keep us updated.
