How long can mystery snails go without food?

Mystery snails can go without food for up to eight days because they can sustain themselves on the algae, vegetation, and biofilm available in the tank.

However, just because they can survive that long without any food doesn’t mean it’s healthy for them. A poor diet and prolonged lack of food can have a huge impact on the snails’ health and shorten their lifespan.

It’s best to feed mystery snails daily to ensure they are well-fed and healthy. You can supplement your mystery snails’ diet with:

  • Sinking fish flakes or pellets
  • Algae wafers
  • Blanched vegetables, such as kale and spinach
  • Sliced cucumber or zucchini
