A shrimp molted, got eggs, and died

Recommended Posts

Hello folks,

I've had this orange neo shrimp in my tank for about 4 months now, and it was generally doing ok. These last 2-3 weeks, it seemed less active, but still ate, so whatever. Last night, it seemed to be actively exploring the tank but not eating. This morning it molted, and I saw it laying on it's side, barely moving. But with some prodding, it would get up and walk around. I then noticed that it was carrying eggs, which is weird because the only other neo (blue) in the tank is also supposed to be female. (At least that's what the guy at the store said. That shrimp doesn't have a saddle, but does seem to have the egg-protecting "side shirts" of mature female shrimp.)

Anyway, this shrimp was near death, usually being motionless, occasionally staggering around and falling on it's back, and then not getting up for a while. I put it in semi-quarantine (i.e. inside a net in the main tank with some plants and a chunk of food nearby) so that the other shrimp won't annoy it and steal its food. But it died after about a day.

When I tried to search on this topic, it seems lots of people have berried shrimp die, but not usually right after molting and getting eggs. I also can't see how this is molting related, as this shrimp, and all others have done it several times in this tank.

As for my tank, yes there is something sub-optimal about it, as my shrimp aren't as active as the ones I see at the fish store. (They aren't active 100% of the time.) The orange neo was relatively active the last 2 months or so, and quickly gained in size over the other shrimp. But then it started slowing down a bit 3 weeks ago, and I think it was getting over-due for a molt. 3-4 days before the molt, it had eaten a lot, so I wasn't worried about lack of nutrition or anything.

BTW, is it possible for a shrimp to be berried with unfertilized eggs?  I am not sure if the only other neo in the tank is male or female.

Tank parameters: Ammonia 0, nitrite 0, nitrate 0 (yes, it has been 0 ever since I've had floating plants)
pH mid 6's
gH 6-7, kH 0-1 due to buffered substrate
temp 71F
other inhabitants: two amano shirmp and one blue neo shrimp, who have also been around for 4 months and are doing fine.

I attached a pic of the orange berried shrimp, and also the potential mate.  Does the blue shrimp look like a female?

Sorry to hear about your problem.

You may be able to save the eggs, JoJo has recently done this (she had the same happen) and I think I attached a yoytube video I saw on setting this up if you have the stuff and want to give it a go, worth it if you only have a few shrimps? I can send another link to the video if you want?

The blue one looks like a female to me! Have you lost any shrimps from this tank in the last 3 weeks, maybe (if you have) that was the father?

The water parameters look more caridina than neocaridinia, but I don't know whether that may have caused the death?

Sorry, but I can't really be of any more help......

No, there haven't been any other neos in the tank for a while now.

I guess that means the eggs are unfertilized and there is no point trying to hatch them.

Hello beanbag!
I apologize that i did not see your thread earlier.
Ok from what i read, there is no such thing as unfertilized eggs. Meaning when the females are berried all of those are gonna be live hatches.
If they are not fertilized, the eggs will not be moved down to her tummy at the bottom as you have seen on your berried mama and they will show the saddle.(sexually matured but not pregnant)

I am so sorry i did not see your thread earlier as i would have encouraged you to give a go at hatching those eggs yourself?
It is possible to do that, kind of gross at first but it is possible.
I know it is a silly question but do you still have those eggs?

For mamas, there are many reasons why they die.
I read a first time mama may "drop" her eggs after molting. In this case, you can also save the eggs.
For me, personally my shrimps used to die because of shifts in water parameters and also during water changes i dont really know what im doing. (I was all over the place)
I have learnt from the kind people here that taught me, getting a book and changing the exact same water amount every time and gradually lowering or altering the individual values very slowly helps.
Than note the date, amount changed, parameters before and after water changes in the book. This helps me take note of what needs to be changed and how to.
@sdlTBfanUK simon always reminds me to drip all new water into the tank very slowly. Quick changes to the water kills them pretty fast.

Please dont feel too sad as well,@zoidburg did mention once that sometimes the shrimps are already advanced in years when you got them? Sometimes its one of those things?

Your parameters i may not be the best to advice you on what is right?
But all i can say is keep it stable most importantly?

I have a 16litre main tank with crystals and blood marys(neos) my gh is 6 and kh is 0, quite similar to yours? And my ph is 6.3 also with an active substrate. Im still using distilled water remineralized. Will switch to rodi when im back from my trip.
If you still have the eggs for any reason, this is what i attempted, by any means it does not look pretty but it works:

https://skfaquatics.com/forum/topic/14201-new-tank-setup-for-yellow-shrimps/
Sorry if its a lengthy thread i think i was very longwinded , scroll down to see what to do with the eggs ok?

This is the video simon shared with me, good as well:



I hope everything works out good for you ok?
Regards,
Jo

Thanks for the suggestions.  But so far, 4 out of 4 people on the internet said that my only other blue neo shrimp is a female.  So I guess that means that if a female carries eggs in her saddle for too long (in this case, maybe 3 months), she will eventually "release" them and then die, or something like that.

Oh really? Never did hear somethig like that. Guess its good to learn new things.
Hope everything is looking up for you.

      Glad we can be of some help and I agree you are doing the best thing by thinking it out thoroughly before you get started. It is very frustrating when you spend a lot of money on a small setup to then have to go and do the same again for another setup because it isn't big enough, way more economical and cost effective to get it right first time, though as you say you are starting with some of the stuff! I'm also sure that when I closed down the small one and moved the shrimps to the new tank that I probably lost half of the shrimplets as they were too small/young to be moved in reality but I really didn't want to have to run 2 tanks for a few months whilst I waited for them to grow - I had way too many anyway. I can't be much help regarding the 'chiller' as we don't have hot enough weather here, in fact even the humans don't get that over here (except in expensive cars)? A lot may depend where you are placing the setup as well, mine is in a dark corner that doesn't get any direct sun. If it isn't likely to get too hot there for a while you can of course come back to that as a separate issue as it won't mean disrupting anything in the tank anyway should you decide to get one later!  You are probably best steering away from the CO2 as it is one less thing to set up and, as you, I have read a lot of reports saying it isn't good with caridina shrimp setups, though I have no actual experience with it, but why risk it. Hope you will keep us informed/updated. Simon

      I agree with you both and you have changed my mind. I will go for mix of cardinia shrimp. Definately will be lot more interesting in terms of colours and patterns.   I do already have most of the stuff. The only thing that I do not is the Chiller and even though I do have the KegKing Co2 setup, I will stay away from it because its a cardinia setup. Will research a bit further into the chiller this, as I do not want to buy one for a small tank and realise that I need to invest on a bigger one down the line. Thank you guys for the input. Really appreciate the insight. P.S: Great pics Simon. That has certainly swayed me towards a mixed setup.

      I started out with a 30cm tank, and it's my only shrimp tank, started of about November with Neo's and added a few Taiwan bee's, king kong, wine reds, pinto's and blue Bolts around feburary, my Neo's have multiplied, but given many away, and finally giving most away, leaving only cardinia, my water seems ok, since many of my cardinia are still here, and my Taiwan bee have berries, shrimplets should come any time. I think you should be prepared to spend money, for me I have a HOF, CO2, water cooler and the right light, i'm intend to change the current substrate from ADA to the PB, but have to wait for the Taiwan bee to have shrimplets.

      Having multiple tanks and a tank rack may be where you want to go eventually but that is probably for the future? If you want to test out the cardina you may want to go the route I did in that having a mix of shrimps colour and pattern in one tank is certainly more interesting to look at than 10 tanks with single/pattern, and I keep getting new ones that I didn't have before, even the boss should like them!!!!! It is obviously a lot cheaper and takes up a lot less time and space as well. I got the 35L dennerle scapers tank (used 3L of substrate) and it is 40cm x 32cm x 28cm and it has 28L of water (my measuring jug is a cheap one so maybe inaccurate, but the tank isn't filled to the brim and stuff in the tank takes up some space). It would give you an extra 10cm x 32cm (plus 2cm x 30cm) which to shrimps is quite a lot, not that I am saying you should necessarily get this tank but just as an example of how less height (which isn't needed for shrimps) in a tank can make a lot of difference to the floor area of a 'similar' capacity tank, but you may think it is too much money for such a small increase, but obviously there is a whole range of other tank choices out there.I assume you would use the heater/light/filter etc from the old tank if you weren't going too much larger? And, of coarse, you can just stick with the tank you have and that should still work out fine for a starter/tester tank? If you want to see the mix then just click on gallery/New images and scroll down. You should show the boss and I a sure it will swing it in your favour! I don't think you should have any problems with caridina if you are sticking with remineralised RO water and proper shrimp products from the very start. It took me years to get to where I am now but I think ALL the problems I had were because I was trying to use 'tapwater', as soon as I started with RO remineralised no problems whatsoever. Any other specifics/question feel free to ask away. Simon

      Thank you very much Simon. I have certainly thought about the idea of secondary tanks. But i wanted to test out the Cardinia waters first. If they do capture my interest, I plan to seek my boss (aka wife) to approve the shrimp tank rack idea *fingers crossed* I have been going through this forum and the Shrimpspot forum to gain as much knowledge as I can to get a good start. Thank you again for your message. Every little bit helps.
