Common name: tryon's hypselodoris

General information

Tryon's Nudibranch, scientifically known as Hypselodoris tryoni, is a vibrant and colorful sea slug found in the Indo-Pacific region. This species is part of the Chromodorididae family and is highly sought after by marine enthusiasts for its striking appearance. The body is predominantly blue with a pattern of black lines and orange or yellow spots. It's important to note that nudibranchs are sensitive to water quality and require a well-established reef tank with stable parameters.

Care

Hypselodoris tryoni requires a specialized diet consisting mainly of sponges, which should be present in the aquarium for them to graze on. They are not suitable for a reef tank with a diverse coral population as they may damage certain coral species while searching for food. A species-specific tank or a tank with non-stinging invertebrates and a plentiful supply of their natural food source is ideal. They are sensitive to high levels of nitrates and copper-based medications.

Reproduction

Nudibranchs, including Hypselodoris tryoni, are hermaphrodites, possessing both male and female reproductive organs. They can lay ribbons of eggs, which are often deposited on the substrate or on the glass of the aquarium. The larvae are planktonic before settling down and metamorphosing into their adult form.

Symbiosis

While Hypselodoris tryoni does not have notable symbiotic relationships like clownfish with anemones, their presence can help control the growth of certain sponge species, maintaining a natural balance in the aquarium.

Habitat

Hypselodoris tryoni is typically found in the tropical waters of the Indo-Pacific, from the Philippines to Australia. They inhabit coral reefs and rocky substrates, usually at depths ranging from shallow waters to about 30 meters deep.
