How big does a assassin snail get?
A assassin snail (Clea helena) reaches about 1.0 inches as an adult. Plan tank size and tank mates around the adult size, not the small fish you buy at the store.
Tank size & setup
Give a assassin snail a minimum of 5 gallons, with water at 70–80°F and a pH of 7–8. As a carnivore-care, carnivore species, a stable, cycled tank with the right diet keeps them healthiest.
Good tank mates
Pair a assassin snail with peaceful species that share its temperature and pH range. Compatible options include:
- Neon Tetra — 1.5", 10g min
- Guppy — 2.0", 10g min
- Molly — 4.0", 20g min
- Platy — 2.5", 10g min
- Zebra Danio — 2.0", 10g min
