They're sort of shiny and white and they can move fast, they're also really agile. Their bodies are sort of a long oval shape.
So yes i think they are copepods. I do try and practice strict hygiene whilst handling my tanks, but i still get water splashed in my eyes on occasion and i use bare hands. The copepods seem to accumulate in my external eheim filter as well.
Thankyou all for the replies as its put my mind at rest.
