White worm ID. Planarian?

[CSremo]

Hi,
I’ve got tons of these guys on the glass at the top of my sump, just out of the water.

Help on an ID and what to do about it?

I would wipe them off - they do not appear to be planaria. Likely they are just eating detritus/algae, etc - in your sump. PS - the reason to wipe them off is if they appear unsightly to you - as compared to any dangerous reason. How big are they? Do you think you might be overfeeding?
