Common name: Blue Dragon Nudibranch

General information

The Blue Dragon Nudibranch, scientifically known as Cycloporus venetus, is a captivating marine invertebrate that is highly sought after by reefkeeping enthusiasts for its striking blue coloration and elegant appearance. This species belongs to the order Nudibranchia, which comprises soft-bodied, marine gastropod mollusks known for their extraordinary forms and colors.

Nudibranchs like Cycloporus venetus are often referred to as sea slugs, but they are much more ornate than the typical slug. They are known for their intricate patterns and vibrant hues, which serve as a warning to potential predators about their toxicity or distastefulness.

Care

Cycloporus venetus requires a well-established reef aquarium with stable water conditions and plenty of live rock for grazing. They are sensitive to water quality, so regular water changes and monitoring of water parameters are crucial. This species feeds primarily on sponges, so it's important to ensure that their dietary needs are met, which can be challenging in a home aquarium.

Reproduction

Like many nudibranchs, Cycloporus venetus is a hermaphrodite, possessing both male and female reproductive organs. They can self-fertilize or mate with another individual. The eggs are laid in ribbon-like masses and will hatch into free-swimming larvae before settling down and metamorphosing into their adult form.

Habitat

Cycloporus venetus is typically found in the Indo-Pacific region, often in shallow reefs and lagoons. They prefer areas with an abundance of their food source, sponges, and are usually observed at depths where light is sufficient for sponge growth.
