Question: do assassin snails reproduce asexually?
Answer: Using Assassin Snails to Control Other Snails They can't reproduce asexually and only lay a single egg at a time so they won't simply multiply in the same manner as herbivorous snails. 2 to 3 Assassin Snails per 10 gallons is a good start for a tank infested with Ramshorn or Trumpet Snails.
