sayurasem I would guess that would be 300 shrimps!

Beer The thing to consider with the pheromones too is that the water circulation may make it difficult to pinpoint the source. A large tank with a small population combined with lots of hiding spots and good circulation may make it more difficult for the males.

frontosa88 For some reason i have gotten good results with larger tanks. All of my tanks range from 20 to 100 gallons. There is no secret. If the shrimp like your water, they will breed like crazy. It's really cool to see a large tank with a few thousand shrimp. Here is a pic of a 50 gallon breed out tank. That's what i call a shrimp ball. You will notice that a lot of breeders don't have a lot of plants in their tanks. That is because it is easier to catch them.

Drewsplantednutz I think the breeders use small tanks to control quality and quantity. And have little plants ease on finding and netting them up

sayurasem Sir you are correct! There's a reason the biggest breeding box is only .5 - .75 gallon depending on the brand.

This thread got me thinking... I once started from 10 CRS in a 10 gallon tank. Six months later I ended up with around 50. Then I thought to my self I better get a bigger tank! Now after more than six months again in a 20 gallon long I only end up with 65.

Now I put all my shrimps back to the 10 gallon with brand new cycled Amazonia lets see how it goes.


On a side note I think population balance is the key to shrimp breeding. Too big of a space and too few shrimps and breeding go slow. Too many shrimps in a small tank and breeding will slow down (maybe?). 65 shrimps was the highest amount of shrimp I had in a 10 gallon but sold some so I'm back to 50.

A plus: if you guys ever watched foreign breeders in youtube, their tanks has little to no plants at all, maybe moss or some other low profile horizontal growing plants. Maybe it is intended so females has no where to hide from the male shrimps?

GeToChKn I'm not saying this is not the definitive answer to why shrimp don't breed, just an observation that I've noticed and see sometimes people have a few shrimp in a big planted tank and can't get them to breed and if water and everything else is in check, it could be something else to consider.

Mr. Leg I have been told by a few people that the ideal tank size for breeding is 10-20 gal. Both for stable parameters and them being able to find each other when its time for the baby making.

I also put a few BKK with 3 female CRS in a 48 gal tank that was scaped but not overly planted. They breed regularly. Same tank had 10 yellows and a few months later I had 60+.

So I think is a combination of size and how heavily planted it is. even in a 20 if you have a few shrimp and a ton of moss, plants and hiding places it will be difficult for the guy to find her. That same 20 gal with less cover will increase the odds.
My suggestion if you want the larger tank for stability and only starting with a few shrimp provide just enough cover/moss to keep them happy. Then add more plants and cover as your population grows.

Good theory but if I was a camper who hunts best at night for my mate that is covered in perfume and leaving a perfume trail everywhere she goes over a 10 mile stetch. Im gunna find that hotty by the end of the night if it kills me.

82nd_Airborne While I agree the idea seems right in principal, i just put 5 yellows in a 20L, only 2 if which were mature. That was 2 weeks ago. Today I saw my female berried. Call it luck or whatever, just thought I'd share.

Senior Shrimpo Are you sure about this? I always believed the males could find the females because of their pheromones. That's why they go all stir crazy whenever a female molts.

I've had the opportunity to set up shrimp tanks of many sizes, and I really don't like smaller tanks. Their fluctuation of water parameters makes it hard to keep the babies alive IMO. So in a bigger tank even if they aren't breeding as much, you're still keeping more stable parameters and retaining more baby shrimp.

Fdsh5 I made the same error with my yellows. I got 12 of them and put them in a 20g. It took forever to get the numbers up. I never considered they would not be able to find each other for some "quality time".
