Assassin Snails will obliterate unwanted pest snails quickly and eliminate the need to use harsh, snail-killing chemicals in your aquarium.


Assassin Snails are one of the most useful animals in the aquarium hobby. We came across them when we had snail infested tanks, but did not want to use harsh chemicals to kill the snails. We have had 30 gallon tanks that were totally overrun with unwanted Pond Snails, and our 5 "Assassins" dealt with over 100 of them within a couple weeks using no chemicals.  They will also rid your tank of unwanted Malaysian Trumpet Snails (MTS), Ramshorn Snails, Bladder Snails, and more.  They are safe to keep with shrimp, fish, live plants, and other aquarium inhabitants because they will not attack anything but other snails.

They are a very attractive color as well. Because of their black and yellow striping, they look fantastic on both light and dark-colored substrates. Assassin Snails grow to about 2 inches long.


  • pH level range: 6.5 - 7.5 
  • Temperature range: 68° - 75° F (20° - 24° C)
  • Water type: Soft to hard 
  • Recommended Aquatic Arts tank mates: Dwarf shrimp (such as Blue Velvet Shrimp, Sakura Red Cherry Shrimp, Neon Yellow Shrimp, etc.), and small to medium-sized, non-aggressive fish. They eat all other types of snails that are their size or smaller, but they will not harm snails that are larger (such as Mystery Snails, Giant Sulawesi Snails, larger Nerite Snails). However, large groups of Assassin Snails have been known to gang up on a larger snail and take it down, so caution should be exercised even with larger snails.
  • Additional notes: Having good substrate is important with Assassin Snails, as they love to burrow in it. Other than snails, they eat leftover fish flakes or invertebrate pellets. Snails are very sensitive to copper, so watch out for copper if you use tap water in your tank.
