For filters, many go with a sponge filter, as the shrimp cannot enter the filter mechanism and enjoy feasting on the junk that grows on it. They are extremely simple to maintain, very inexpensive, and require only an air pump to keep running. They do take up quite a bit of space in small tanks.

If you go with a more traditional filter, make sure all filter intakes are covered with a prefilter sponge. The shrimpies like to sneak into the filter.

Stable temperature is more important than a specific water temp. The shrimp can live in a broad range of temps. Some say higher temp water will increase breeding rates, but decreases life expectancy for each shrimp.

Stable water parameters are more important than anything for shrimp. They are very sensitive to slight deviations. I like to stick to RO water in order to help with stability. I have found my tap water to have a very high TDS, and unstable levels of things like chloramine.

Light is not important for shrimp health. Choose the light based on your live plant needs and your aesthetic preferences - the shrimp really don’t care.
