Cherry shrimp in filter

[FishAreCool1]

Recently i added 6 cherry shrimp into my 13 gallon tank and one has just started hanging out in the filter. he doesnt seem to be in any distress. is this something i should be worried about?

I’d think all fine - I have a thriving colony in the canister filter sponges.

Do you have a pre-filter sponge?

Well, what model filter do you have? I agree with the above, simply add a pre filter course sponge to the intake.
