Design for feeding and movement

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

  • Check adult dimensions and social needs for this species; small body size alone does not establish aquarium suitability.
  • Provide swimming space and refuge, and choose companions with compatible feeding behaviour.
  • Match food size to the animal and observe feeding directly, especially when keeping small species with faster feeders.
