Common name: loch's chromodoris

General information

Chromodoris lochi, commonly known as Loch's Chromodoris or the Blue Nudibranch, is a strikingly beautiful sea slug found in the Indo-Pacific region. This species is part of the Chromodorididae family, which is known for its vibrant colors and intricate patterns. The body of Chromodoris lochi is predominantly white with a blue border, and it has a series of black lines running down its dorsum. The rhinophores and gill structures are typically a bright orange or red, creating a stunning contrast against the white body.

Care

In the aquarium, Chromodoris lochi requires a well-established system with stable water conditions and plenty of live rock for grazing on biofilm and microorganisms. They are sensitive to water quality, so regular water changes and good filtration are essential. It's important to note that nudibranchs like Chromodoris lochi have very specific dietary needs, often feeding on particular types of sponges found in their natural habitat, which can make them challenging to keep in captivity for long periods.

Reproduction

Chromodoris lochi is a hermaphrodite, possessing both male and female reproductive organs. They can lay spiral ribbons of eggs, which hatch into free-swimming larvae. These larvae will eventually settle and metamorphose into the adult form, provided they find the appropriate food source, which is typically a specific sponge species.

Habitat

This nudibranch is commonly found in the tropical waters of the Indo-Pacific, from the Red Sea to the Western Pacific. They inhabit coral reef environments, often seen on or near their preferred food source, sponges. They are usually found at depths ranging from shallow waters to about 30 meters deep.
