Assassin snails are true to their name - they will dutifully take care of pest snail populations in any aquarium.
It is easy to unknowingly introduce pest snails as they are commonly brought in on plants as hitchhikers, and once in the tank their populations boom. Assassin snails are carnivorous and will eat any snail in the aquarium, so they are only recommended when you have pest snails the same size as assassin snails or smaller. The two most common pest snail that the assassin snails will take care of are Trumpet Snails and Ramshorn Snails.
Assassin snails grow to a max size of 3 inches and are recommended to tanks of at least 30 gallons. The general rule of thumb is to have 5 assassin snails per every 15 gallons. They like their temperatures between 68-74oF, pH between 6.5-7.5, and dKH between 2-15.
