I just purchased an assassin snail to rid the pond snails out of my aquarium. I have a 45 gal
aquarium and I bought one assassin. I read somewhere that they won't eat pond snails all the time because they are faster than the assassin, and that they only eat snails closer to their size and leave the smaller ones alone, is this true? I would also like to know if assassins are asexual like pond snails or do they breed with other snails?
