so i came home to find one of my females molted and i think she might have mated but im not sure. so i was wondering how long after the mating does the female show berries? also do male shrimp take longer to mature than females?

Generally takes just a few hours for them to form berries, I've watched everything happen from molting, mating, to berrying and it was within 3 hours the female started berrying, next day she was fully berried. While they are berrying up I've noticed they'll bend their bodies...almost like a woman doubling over with cramps. At least that's how it's been with my neos and CRS. Other shrimps might be different and I suppose each shrimp could be different.

Oh that depends on quite a few things...temp being one. I've got PFR/Supremes that are 4 months old that are still very small due to being in 70 degree tank temps. They are about the same size as a 2-3 week old neos in 76-78 degree tank temps. Bump the temp up and yeah, they grow super fast. But keep the temps low and growth slows. I've got a few 5 month olds that are still subadult size and just developing saddles.

But yes, on average with normal temps more in the 74-78 range (again just talking about neos here), those figures look about right:)

once they mate they show berring quickly... and um.. mating looks like they are dead on their side..

i every time one delivers in my tank they are berried like the next day or so...

Thanks for catching that, raven. :)

Shrimp growth + Temp = K

K is a constant. Temp definitely plays a role.
The higher the temp, the faster growth.
The lower the temp, the slower the growth.

However before everyone throws heaters in their tanks: Metabolism and temperature equates to how long your shrimp will live as well.

Shrimp longevity + Temp = K

Where K is a constant.
The higher the Temp, the shorter your shrimp will live.
The lower your temp, the longer your shrimp will live.

Yes indeedy! Shorten ye old lifespan at the higher temps, least that's what I've read. Those Supremes I sent to you, the medium sized babies that were in there were already 8 weeks old when you got them. Tiny little things but I kept it a cool 68-70 degrees in that tank. I have doubt they'd have been big enough to be saddled if I'd been running that tank as a neo only tank (which I would normally keep those at higher temps just for growth). I have a shrimpie journal and I write down every time a batch of babies is born so I can track those growth patterns.
