long term shrimp keepers... how long do your shrimp live???

[Magnum Man]

I get that the temperature makes a big difference... all my neo breeder tanks are kept at cooler temps... but I think they breed faster at warmer temps, but I've been keeping those tanks, in the low 70's F.

adding them in with "tropical" fish is supposed to be possible, but seems to shorten their lives...

I'm assuming most shrimp species have similar life spans???

I had Amano shrimp in a tropical tank, for around 2 years before that colony died out... but they were added as jumbo's so they were probably 6 to 12 months old??? when they came here... this being, IMO important info, since they don't breed in normal aquarium set ups...

I have several cherry shrimp in my Hillstream tank, that seem to be thriving ( that is a cool water tank, in the low 70's F. ) if they are breeding, I'm sure the babies become a food source for the fish in that tank, but I regularly see the bright red adults in the tank...

AI ( internet ) say's neo's typically live 1-2 years, but can live up to 5 years, quite a range which is most like temperature related...

curious if any members here are long term shrimp keepers, and can add to this???

It's a tricky one. That dead shrimp - is it an elderly one or one that has only just reached adult size? I can't recognise individual shrimps to be able to tell.

All I can say is I got my first red Neos in 2013. I had these red ones in a separate tank but moved them into my main tank a few months ago. The colony is 12 years old but I have no idea how long the individual shrimps live.

My colony is three years old. I recognize one particularly large red neo that is at least one year old.

I suspect not, my group of amano's are over 5 years old with no losses. IIRC @Essjay had a 7yo amano.
My neos are an established colony (some tropical, some temperate). It's possible there are long lived individuals but I'd guess they have a shorter life than amanos.

It was 6 years rather than 7. But still along time.

I guessed the shorter lifespan of my Amano's was due to the "tropical" temps, and having no way to guess the age of "jumbo" shrimp
