FROM THE SIGNATURE COLLECTIONS

Look closely

Mature males have a dark tail filament and separated pale bands in the fins. These details help distinguish true P. deissneri from round-tailed fishes sold under its name.

A detail worth knowing

The name was historically applied to several licorice gouramis. Female identity is harder to assess visually, making locality and breeding-line records especially valuable.

Planning for licorice gouramis

Care-planning notes. Confirm exact requirements for the species and source population.

  • Prepare species-appropriate soft, acidic water and a dependable supply of suitably small live foods.
  • Provide shaded cover and breeding shelters. Keep separately documented species and localities distinct.
  • Use a specialist breeding guide: regular tap water and a dry-food-only plan are not a reliable starting point.
