winter breeding

Recommended Posts


Hello there.

How is your breeding routines going?

it have been years now , that shirmps dont breed in winter, i keep aroud 20 tanks.

Shrimps stop breeding from novemer to march.

Temp no plays role,  i keep tanks without heat and tanks with heat , also some tanks with more light and some wiht less.

I saw crs breeding in 15c,,,, and in another tank with 22 c from 200-300 srhimps no one breeding with same light.

After a  lot of research the only think that it play roles in winter is barometric presure.

The crazy is that a friend living here , he saw some breeding in winter.

The only think its in my mind is that my shrimp room dont have a good  insulation so barometric presure is the same as outside...

In house with a good insulation  aircodition can change the barometric presure, and keep it stable .

What is your opinion about breeding in winter ?

I've had 3 berried females, only one after adding a heater. Two were bloody mary, one a YKK. My YKK colony is pretty young still so first berried female from the group.

Unfortunately, a bacterial infection or something wiped out many of the Neos, including many of the babies and I haven't seen signs of the YKK offspring yet... so it could be better! 


I know many people experience slower breeding in winter. One breeder/reseller said that he put a heater in his shrimp room (small bedroom converted shrimp room - door is often open to the rest of the house with a gate to keep the pup out) which helped to increase breeding.


I don't have a shrimp room, tanks are in living space.

There is a good video about Taiwan bee shrimps not breeding in winter so it is worth watching if this is something happening to you, great videography as well?


My taiwan bees aren't breeding and I suspect that  it is because it is winter here and so it was really bad timing on my part as they probably reached breeding age as winter started, d'oh!

I think I have said elsewhere on here, but can't now find it (my bad) that my small 15L tank I started with didn't have this happen but I found my old notes and babies/berried shrimp actually didn't start to be seen until end of March (then it went crazy) so again it appears to confirm this affected that tank as well, and it doesn't seem to matter the size of tank if this is correct.

Annoyingly this means I have to try and keep these adults alive until spring, though I can hope there may be some babies soon (oblivious)??

      I just got a buried orange Sunkist female from my lfs and I have a cherry shrimp Tank. What would happen if I put the orange Sunkist shrimp in that tank? Is it a good idea? Would it creat wild type?

      yes indeed :) Thanks for the compliment!

      ^ agree to all of that 🙂 Tub method is the way I went, worked a charm. Now I use the tub as a fish-storage container. Took me most of the day to get through the whole process with a slightly overstocked 29 gallon tank - hence way more gravel. I think yours is only a 10 or something? If you switch the heater and filter to the tub, it can hold the fish and shrimp for a week or so with no problems, so you are able to take the safe approach - leaving the livestock out of the tank for a few days to let the tank settle.

      As stated byothers, there really isn't any short cuts that really are 'short cuts' in the end,, best to just empty and refill, a friend of mine did his 160L this weekend and it took about 4 hours doing as recommended above. He was replacing gravel with soil substrate as he wants to have a go at keeping more plants. He has a lot of my cull red cherry (browns) and fish so wasn't wanting/needing a buffer substrate so he is using this; https://www.tetra.net/en-gb/products/tetra-activesubstrate He also used the 'complete substrate' underneath which is probably more important with plants, as that has the minerals etc. but if you just like/want the look of the soil and to grow a few easy plants maybe you could just use the active substrate on its own. I know my friend won't have kept the fish separate from the tank once he put the new substrate in, so they will have gone back the same or next day so will be interesting to see how it works longer term, but he is using the 2 substrates which may/probably get either an ammonia spike or build up of minerals just like all the other substrates due to the Tetra complete substrate being used as well? If you can keep the fish in a different container as JayC recommends, even for just a week to let the new tank settle and test Nitrate/nitrite/ammonia over that time would be safer than just putting the fish/shrimp straight back once the new substrate is in place, also as JayC states. Having read up on this there also appears to be Seachem Flourite and I believe these 2 products are inert from the research I did. I would be interested to hear if anyone knows as that should mean they would be ideal for neocaridina shrimps if you want the soil type look??? I am assuming these products are available in USA. I had thought I would use the 'Tetra active substrate', on its own if I reset my oldest tank that has tetras and RCS but even after 5+ years the plants grow so ridiculously well, there is no point changing it, I don't use any fertiizers either. I haven't used the Fluval substrate so am not familiar with that! Simon

      Any substrate for plants will release a certain amount of nitrogen (ammonia).  Ammonia is harmful to fish and shrimps. So, yes, they all contain some form of toxin.  You don't want the livestock in the tank when new substrate is added. It's advisable to move them out to a temporary tank or container while you change the substrate and let it sit in the tank with a mature filter for a few days before reintroducing the livestock. As Crabby mentioned the best way to do it above. Catch all the livestock and rebuild the whole tank at once. Keep your filter running in the temporary tank/box. Just get a cheap plastic box if you don't have another spare tank.   This box can always be used for other storage items, or as an emergency hospital tank after you finish with this project.
