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:

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.

      Thanks for that, I think I will try that just so that I know, though I don't think they will be going back into the tank now. Will be good to know though whether they were the reason. Simon edit 1hr later - I have done this, and also put some of the water in a cup to test the water itself, will leave both a week and report back. Ph was 5.5 when set up

      My guess is a fungus, so remove it as much as possible and do water change (slowly). The common causes of fungus are overfeeding (left over food), something that is decaying (plants or animals), or something emitting sugars, like driftwood.
    • beanbag
      acid test them or leave it in a glass of remineralized water and check its pH again after a few days.
    • sdlTBfanUK
      All the other parameters are stable and perfect, and the newly filtered remineralised water that goes into the tank when doing a water change is Ph5.5. I use the dennerle mineral double in place of salty shrimp as it is easier to use being a liquid! I do 10% water changes each week. It is a bit baffling to me but as there is no obvious problems at this point I am not too worried but will probably get some new substrate ready, just in case. The substrate that is in the tank is a year old and as mentioned the only other unknown that may have caused the problem was I had 3 geodes in the tank, which are a type of rock? Simon
    • sdlTBfanUK
      I leave the sides and back alone as well and the shrimplets seem to come out onto that a lot and IF there are new borns that is the only place where I get to see them. When you do a water change you need to add in the new water very slowly also, most use some sort of dripper setup. It may just be that the setup wasn't established enough, that is what I put my fungus down too anyway. Mine wasn't really anywhere that I could remove it but it cleared in less than a week, but if you can remove some manually I would do that.I imagine just adding the shrimp may cause a small/temporary imbalance as it then has to adjust again, if that makes sense?  Hopefully you won't loose any more shrimps, and I wouldn't worry too much about the fungus unless it just keeps getting worse, as I have had this happen a few times with newish tanks and it has always just cleared up in about a week.
