Species Profile

Black Mystery Snail

Pomacea diffusa

Why We Love This Snail

  • 24/7 algae control
  • Won't eat healthy plants
  • Shrimp-safe community tank
  • Fascinating to watch

Black Mystery Snails are color variants of Pomacea diffusa, the common aquarium mystery snail. Their dark charcoal-to-black shell coloration coloration adds a strong visual accent while their large shell and active behavior make them easy to observe.

They are peaceful and generally compatible with shrimp and community fish, but still need direct feeding and calcium support for healthy shell growth.

Care Notes

Feed Mystery Snails directly with sinking foods and vegetables. Do not rely on algae alone.

Maintain adequate calcium and minerals for shell growth and avoid copper-based medications.

Expert Advice
Razz Aquatics Recommendation

Use a mature aquarium with stable mineral content and a secure lid. Feed sinking foods and blanched vegetables several times per week and provide supplemental calcium if your water is soft.

Maintain stable, mineral-rich water and provide a calcium source if your water is soft.
