This is making me paranoid. I'll be poking a small hole about 1mm wide into a soda bottle, put a pellet of fish food in it, leave it in the tank with the hole on the substrate, remove it in the morning to wash the planaria away, then repeat the procedure.
If planaria really do limit shrimp populations, then it's not necessarily a bad thing since I don't want my tanks to be overpopulated with shrimp. But I'll use the bait'n'bottle method to see if it really does positively impact shrimp populations.
