LF Brown planaria (flat worms!)

I'm looking for Brown planaria to populate a microfauna tank. These guys are normally pests in your tanks, eating the food you give your other animals.

Location in Wisconsin, hoping to find a local person but will accept the risk of shipping them if I need to.

Edit: Found some plus some great plants to get my "planarium" up and running. Thanks to u/bquad and if you're interested in how this turns out, check out r/Jarrariums in a few weeks. There is still a question of whether the little guys will thrive under the conditions I'm planning.
