How old is your oldest shrimp?

So I did the math on how long I have really had my Amano shrimp - and my estimates are a few months shy of 3 years. This seems unreasonably old. Anyone else have granny shrimp?

My Amanos are probably 5 years old. A breeder told me they can live up to 7. I don't think there is another that lives as long. I could be wrong though.

Amanos live nice and long, and the best part is they get hungrier as they get bigger, meaning they eat more algae per day!

Unlike SAE which lose their appetite for algae as they age, amanos keep chowing down. My most recent import of amanos yielded 5-6 giant ones, which I added to my other 3 giant ones, and I can put any algae ridden decoration or driftwood in there and have them pick it clean in a day or two. They really like hair algae, and they're constantly picking the glass clean as well.

As far as dwarf shrimp are concerned, I had one CBS that lived just over 2 years.

I had 2 of my 6 amano shrimp for over 8 years and they were adults when I bought them. No telling how old they really are.

Came back to this thread to validate the 7 year lifespan of the amano shrimp. One of my Amano recently passed the 7 year mark.

I have some opae ulas I got back in 2017.... so they ought to be 2+ years old by now... with no idea how old they were when I got them.

To be fare though... these tiny little shrimp, smaller than Neos, can live for 20+ years.
