Details

Assassin Snails (Clea helena) are one of the most useful animals in the aquarium hobby.  They will obliterate unwanted pest snails and eliminate the need to use harsh, snail-killing chemicals in your aquarium.  They are particularly adept at handling populations of pond snails, Malaysian trumpet snails, ramshorn snails, bladder snails, and more!
 
To demonstrate an example of the Assassin Snail's prowess, we have kept several 30 gallon tanks that were completely overrun with hundreds of unwanted pest snails, and a crew of 5 "assassins" demolished them within a couple of weeks.  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, and 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 when keeping these, even with larger snails.  They are safe to keep with fish, invertebrates, live plants, and other aquarium inhabitants because they will not attack anything but other snails.
 
As an added bonus, Assassin Snails are rather attractive in appearance.  Due to their yellow and black/dark brown striping, they look fantastic on both light and dark-colored substrates.  Their shells are spiral-shaped and taper down to a point at the end.  Their bodies are an iridescent, almost translucent white color and consist of a long Proboscis (a sucking mouthpart, similar to a nose) that they use to drag themselves around, as well as two eyes underneath two tentacles.
 
We ship younger Assassin Snails that are about 1/2 to 1 inch in length, and they will grow to about 2 inches long as adults.  Having good substrate is important with Assassin Snails, as they love to burrow in it; we recommend sand.  As with all snails, these are very sensitive to copper, so we advise monitoring copper levels if tap water is used to fill the tank.
