Planaria in my shrimp tank

[stpierce]

Over the past couple weeks I started to notice that I have planaria (I think) in my 10 gallon shrimp tank. Not like 1 or 2, more like a dozen+. I have read they aren't harmful and come from overfeeding, I have shrimp so the food needs to sit for a little while before they finish it and I don't think the planaria have any predators in the tank. Should I be concerned? some are almost an inch long.

They're nothing to worry about.If you want to reduce them, just do an extra gravel vacuuming or two.
