Found this after cleaning XP3

[Erniec]

I have no idea what these are , I found them in my XP3 filter so I poured the water in a bottle to take a vid, they are small and hard to see, is there a concern here ?

They are crustacean called "cyclops" live food for large fry and small fish. Do not use them to feed small fry because they attack small fry. They can be cultivated like Daphnia.

To know where you recieved these,a full knowledge of anything added to tank that was alive. Water plants,fish,live foods etc. Maybe even substrate idoms that were still wet. Copapods live everywhere in our local envioronment, and can be picked up easily.

Not at all, this is means your environment is cycled and health.
