I have read all over about quarantining plants. I honestly never do, I do a good look over at the store, in the bag, and when placing it in the tank. Grab some Assassins as snails will be there eventually. Just being honest, I have been keeping tanks for years and years and only occasionally quarantine fish. Guess most of the tanks are solitary species tanks so that makes it a little less risky.
