Will a betta kill a snail?

Yes, a betta will kill a snail. While bettas can and do kill snails, this usually only happens when the betta is especially hungry or aggressive.

Betta fish that are less aggressive, especially female bettas, can cohabit with snails with no problem. If you decide to get a snail as your betta’s tank mate, be sure to assess your betta’s temperament first.

Here are the top signs of aggression in your betta that you should watch out for:

  • Flaring its gills and fins when it sees another fish
  • Trying to attack its own mirror reflection

If your betta displays these signs, adding a snail to its tank may not be a good idea.
