Planaria ... Problem?

I've been in the habit of turning my aquarium light on for a few minutes at night (to see my RCS as that is the only time they aren't hiding under a piece of driftwood) and I've started noticing a few small Planaria sliding around on the glass. I'm not sure if they have always been in my tank and I'm just noticing them now, or if this is a recent development. I usually only see between 3 and 6 it a time, and they are really pretty small, like ~1mm long. The smallest ones are white, and the larger ones have more of a greyish pink color.

Should I be trying to exterminate them? Is this a sign of poor tank health? Can they hurt my fish, shrimp or plants?

If they are bad, can anyone recommend a product or maintenance strategy to get rid of them?

Hello m...

These small worms don't harm the tank or the inhabitants. Fish generally eat them. If you're keeping the tank water clear of dissolved fish wastes through frequent water changes, then you have nothing to worry about.

Some say they attack shrimp but that's pretty rare, if u have a healthy population of shrimp u have nothing to worry about. Also make sure what u have is planaria as there are other nematodes that are often confused as planaria but are harmless

I just discovered planaria in my betta tank too. I know they're harmless, but I still don't want them in there lol I occasionally see my betta pick them off though, so I guess it's kinda cool.

You can build a planarian trap, a box with holes only they can enter with fish food inside. Remove when there are lots inside and repeat, like a snail trap.

Are you sure they are planeria, and not detritus worms? Google images is your friend.
