Common name: lumpy goniobranchus

General information

Goniobranchus hintuanensis is a species of colorful sea slug, a nudibranch, belonging to the family Chromodorididae. These striking creatures are known for their vibrant patterns and hues, which can range from bright pinks and purples to yellows and oranges, often with intricate designs that serve as both camouflage and a warning to potential predators about their toxicity.

Care

Goniobranchus hintuanensis requires a specialized aquarium setup that replicates their natural environment. They are sensitive to water quality and require stable, clean water with low nitrate levels. A well-established reef tank with plenty of live rock and a low population of potential predators is essential. They feed on specific sponges, so ensuring a food source is critical for their survival in captivity.

Reproduction

Like many nudibranchs, Goniobranchus hintuanensis is a hermaphrodite, possessing both male and female reproductive organs. They can self-fertilize or mate with another individual. After mating, they lay spiral ribbons of eggs, which hatch into free-swimming larvae before settling down and metamorphosing into their adult form.

Habitat

Goniobranchus hintuanensis is typically found in the tropical waters of the Western Pacific, including the Philippines. They inhabit coral reefs and are often seen crawling on or near their preferred food source, sponges. Their presence in a reef tank can indicate a healthy and mature system.
