Common name: Crimora lutea

General information

Crimora lutea, commonly known as the Yellow Crimora or Yellow Dorid, is a species of colorful sea slug, a nudibranch, within the marine gastropod mollusk family. This small and strikingly vibrant nudibranch is known for its bright yellow coloration, which can vary from pale to a deep, lemon yellow. The intensity of its color can be a visual indicator of the diet and environment in which it lives.

Care

Caring for Crimora lutea in a home aquarium requires attention to water quality and the availability of its natural diet. They are specialized feeders, primarily consuming bryozoans, which must be present in the aquarium for them to thrive. Stable water parameters and a well-established tank with live rock are essential for their well-being.

Reproduction

Crimora lutea reproduces through a process called spawning, where eggs and sperm are released into the water column. In captivity, breeding is rare, but if conditions are right, they may lay spiral ribbons of eggs on the substrate or aquarium glass.

Habitat

This nudibranch is found in the Eastern Atlantic, from the British Isles to the Mediterranean Sea. They inhabit shallow waters, often seen on bryozoan colonies, which are their primary food source. In the wild, they are typically found at depths ranging from the intertidal zone to about 40 meters.
