I recently bought some chaeto from my LFS 3-4 weeks ago, placed it in my small mini HOB refugium to get settled in.
Fast forward weeks later, I found myself with a bloom of copepods on my aquarium glass. The reason being i found my clown pecking at the glass, a behavior i noticed if i skipped a feeding or he found some copepods crawling in his corner.
The fun thing was, The copepods that hitchhiked on the Chaeto are also taking refuge in my canister filter. I removed some air bubbles in my canister and some larger copepods flooded out the outlet hose. So there is a very good chance copepods can populate in your canister filter in the right conditions.
