Common name: Glorious Flatworm

General information

The Glorious flatworm, scientifically known as Pseudobiceros gloriosus, is a vibrant and colorful species of polyclad flatworm. This species is renowned for its striking appearance, featuring a combination of bright colors and intricate patterns that make it a visually appealing addition to any reef aquarium. Despite their beauty, these flatworms are not commonly kept due to their predatory nature and the difficulty in providing them with a suitable diet in captivity.

Care

Caring for Pseudobiceros gloriosus in a home aquarium is challenging. They require a specialized diet consisting of small live invertebrates, which can be difficult to sustain. Additionally, their predatory behavior may pose a risk to other small invertebrates in the tank. A species-specific or predator tank with ample hiding places and a well-maintained environment is essential for their well-being.

Reproduction

Glorious flatworms are hermaphrodites, possessing both male and female reproductive organs. They engage in a unique mating behavior known as "penis fencing," where two individuals spar with their dual penises until one successfully inseminates the other. In captivity, breeding these flatworms is rare and requires a deep understanding of their reproductive needs.

Habitat

Pseudobiceros gloriosus is typically found in tropical and subtropical marine environments, often residing on or near coral reefs. They prefer habitats with plenty of crevices and overhangs to provide shelter and hunting grounds. In the wild, they are usually seen at depths where light is sufficient for their prey to thrive.
