Can Mystery Snail Live With Swordtail?
Maybe, with caveats. Mystery snails are peaceful and slow-moving, but swordtails are active swimmers that may accidentally damage delicate snail antennae.
Why
- Mystery snails grow to 2 inches and spend most of their time on tank surfaces, glass, and plants.
- Swordtails at 4-5 inches are active mid-level swimmers that rarely venture to the bottom where snails graze.
- Temperature overlap of 72-82°F and pH overlap of 7-8 work for both species comfortably.
- Mystery snails have long antennae that can be nicked by fast-moving fish during feeding frenzies.
- Mystery snails are peaceful and add negligible bioload. They help clean algae and consume decaying plant matter.
What could go wrong
A mystery snail may get its antennae damaged during rough feeding times if swordtails crowd the surface at mealtimes.
Gear for a shared tank

AquaClear 30 Power Filter
Oversized filtration is what lets you stock two species together without water quality crashing. Rated for a tank slightly larger than the 20 gallon minimum.
Eheim Jager 150W Thermostat Heater
Holds a steady temperature inside the 72-82°F window both species need.
API Freshwater Master Test Kit
Keep ammonia, nitrite, and nitrate in check. Two-species tanks have more bioload and less margin for error than single-species setups.
Better pairings to consider
Nerite snails are equally peaceful but have shorter, more protected antennae and harder shells.
