Shrimp and filters
Baby shrimp are the size of fruit flies. Any filter intake wider than 1mm can pull them in. The safest option is a sponge filter; the second safest is a pre-filter sponge over a standard intake.
Sponge filters are also the easiest filter type to maintain — a monthly rinse in tank water and that’s it. They’re the default for dedicated shrimp breeders for a reason.
If you’re running a mixed plant-and-shrimp tank with a larger canister, add a generic pre-filter sponge to the intake. It costs less than a drink and makes the tank shrimp-safe.
Quick answers
FAQ
- Can I use a canister filter for shrimp?
- Yes, with a sponge pre-filter over the intake. Without one, baby shrimp vanish into the canister.
- Do shrimp tanks need a filter at all?
- For a dense shrimp colony, yes. A heavily planted tank with low shrimp density can go filterless with very frequent water changes, but a sponge filter is so cheap and low-risk that there's no reason to skip it.
