Fish Zole 250mg 100-Tablets contains metronidazole, a nitroimidazole antiprotozoal and antibacterial. Metronidazole targets protozoa and anaerobic bacteria. It is one of the main tools hobbyists use against internal flagellates such as Hexamita and Spironucleus.

Spectrum: Protozoan parasites and anaerobic bacteria. It is not a general-purpose antibiotic.

What it is commonly used for

Aquarists and keepers commonly turn to this ingredient for:

  • Internal flagellate infections
  • Hole-in-the-head disease in cichlids and discus
  • White, stringy waste and appetite loss
  • Some cases of bloat

Things to know before you treat

  • It does not treat external parasites such as ich or velvet; those need a different approach.
  • Medicated food is often used because sick fish may refuse it, so many keepers dose the water.
  • Treat in a hospital tank.
