Sounds like you may have Planaria in your tank. Planaria are flatworms, related to flukes and tapeworms. They are quite small and hairlike. Take a good look at them and you may see a hammerhead shape on one end with eyes.

Bottom line, they are not harmful to turtles.

However… they are an indicator that the tank has a problem. Either you are feeding your turtle (You do have a turtle, right? Making an assumption here since you didn’t mention, but you are asking this question on a turtle website) too much, or you are not cleaning your tank enough.

I say this because Planaria require a food source, which means there must be excess food wastes in the tank to support them.

If you want to get rid of them, you should:

• Clean your tank thoroughly. Really get into the gravel as that is where the worms find food. Remove dead plants and other waste.

• Cut back on the amount you feed your turtle. Excess food not eat becomes part of the waste and can sustain the Planaria as well.

• Finally, once the tank is clean, make sure you keep it clean. Change the water frequently and do regular maintenance. A clean tank = no Planaria!

Good luck!
