Depends on the flatworm. Some are predatory, some come in plague proportions, some are just unsightly. Which ones are you referring to?

don t know which ones I have but I have a bunch. I have never seen them doing any damage. my camera sucks so I cant get a good pic of the little critters.

my whitish ones don't seem to do any harm, at least nothing noticable.

I did see something very interesting the other night b4 the lights went out. It was something with 4 legs that had roughly 6 joints per leg and was a purplish color. It was about as thick as piece of #18 wire and the legs were about 1.5" long. It was walking around like a spider or something

sorry i got off the subject I would say they are probably brown.
What should I look for them doing?
