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.

      I just use an air line and a valve to set the drops and let it run.  It requires zero supervision.

      I have a reply from them on the cost, there is no minimum order. Message me if you are interested, the cost is very reasonable, in fact cheap compare to the cost in Hong Kong, and they send worldwide, I don't want to post on this forum, without there permission.

      Thanks @sdITBfanUK and @ShrimpNewb. For the last month or so the RCS and Darwin Algae Eater shrimp were growing and colouring up well with the small water changes I was doing. The water I have hovers around ph of 6.4 and I have Amazonia substrate. I thought the RCS were tougher than other shrimp and I know others have commented that the WP were closer to Caridina preferences. RCS are cheaper here, my LFS stock the plain red ones so I thought I would start with them. Anyway, will try smaller changes and dripping them in. It really is a balance isn’t it? Shrimp first or a lush planted tank first. Different requirements. I need to make a drip system for bigger changes. Thus far when I was “drip acclimating” the shrimp to put in the tank, I used a syringe over several hours. Dripping 6 litres by syringe might be rather tedious.

      pH does seem pretty low.  From what I've read, neocaridina like the pH in the low to mid 7s and struggle to survive below 6.5.  I'm new to this hobby too and I would definitely listen to Simon, as he has given me a bunch of good advice thus far.   Also, when I was researching shrimp, I was advised to avoid planted aquarium ferts because they negatively impact the shrimp.  That may be the reason for the deaths.  Unfortunately, I know nothing about the Dino products, though I am avoiding Seachem Excel and the other ferts I normally use in my larger planted tank for the neocaridina tank.  You may want to look into other ways to combat algae.
    • sdlTBfanUK
      The water parameters are more caridina than neocaridina! I wouldn't do a 50% water change unless really there was a serious problem. With water changes anyway it is best to drip the new water into the tank, this will also mean you don't need to worry about the temperature difference of the 2 waters. Shrimps normally swim about more when you do a water change anyway, it also can trigger breeding and molting - I guess it would be the equivalent of heavy rain in nature! You may also want to check the plant food is ok as they may contain something not good for shrimps, generally I believe it is better not to use plant feeds and don't use them. Hope everything settles down and you don't lose any more shrimp. Simon
