Are your fish too big to eat the planaria? Cause I've only had planaria in tanks before the fish moved in. But yeah, Panacur (that's the dog dewormer with Fenbendiazole in it) works really well to kill them. Just keep it in the tank for a few days so the planaria all die off. And keep in mind that you can never keep nerite snails in the tank after that unless you strip it down and replace the substrate. But if nerites are not in your future, it does a great job and doesn't harm fish or shrimp.
