Short answer

Most care guides say cherry shrimp live about 1 to 2 years. Cooler, stable water tends to mean a longer life, and warm water a shorter one. Because a healthy colony keeps breeding, the colony can last much longer than any single shrimp.

What the guides say

The numbers are close across shrimp breeders and care guides:

Source	Lifespan
Shrimp Science	About 1 to 2 years
Shrimp and Snail Breeder	12 to 18 months on average, up to about 2 years
The Shrimp Farm	At least a year, and up to two; an older care article says about two years on average
Flip Aquatics	1 to 2 years
Wikipedia	1 to 2 years

So a cherry shrimp is a short-lived pet. That is normal for a small shrimp and not a sign that you are doing something wrong.

Temperature makes the biggest difference

Shrimp are cold-blooded, so warm water speeds up their whole life: they grow, breed and age faster. Aquarium Co-Op says higher temperatures shorten their lifespan, while lower temperatures lengthen it but slow breeding.

Shrimp and Snail Breeder gives rough numbers. At about 20 to 22 °C (68 to 72 °F), cherry shrimp live closer to 2 years. At 23 to 26 °C (73 to 78 °F), the average drops to 12 to 18 months, and above about 26 °C they age faster still. For the longest life, the site suggests about 21 to 22 °C (70 to 72 °F).

That gives you a simple trade-off. Slightly cooler water means longer-lived shrimp. Slightly warmer water means more babies.

What else matters

Steady water. Sudden changes in temperature, hardness or TDS (everything dissolved in the water) can cause failed molts, one of the most common reasons shrimp die early. See our water parameters guide.
Clean water. Ammonia and nitrite should always read 0.
Good food, in small amounts, with some minerals and protein.
No copper from medicines, fertilizers or food.

You rarely know how old your shrimp are

Shrimp sellers often ship young shrimp, up to a few months old. So when you buy shrimp, part of their life has usually already passed, and you can't be sure exactly how old they are. A group bought at the same time will also grow old at about the same time, which is one more reason to let them breed.

How to help your shrimp live longer

Keep the temperature steady, on the cool side of the range if you don't need fast breeding.
Only add shrimp to a fully cycled tank, and test the water regularly.
Change small amounts of water and add the new water slowly.
Feed small amounts and remove leftovers.
Move new shrimp over slowly with drip acclimation.

Is it normal when a shrimp dies?

An occasional death in an older colony can simply be old age. Several deaths within a few days are different and usually point to a problem with the water. In that case, read our guide to why shrimp die and test the water first.

A colony outlives its shrimp

In a good tank, cherry shrimp breed on their own. New babies keep replacing the old shrimp, so the colony can go on for years. Our breeding guide explains how to help it along.
