Common name: Chiton affinis

General information

Chiton affinis is a species of chiton, a type of marine mollusk known for its distinctive eight-plated shell. These invertebrates are part of the class Polyplacophora and are commonly found in tropical and subtropical oceans. They are known for their ability to cling tightly to rocks and other hard substrates in intertidal zones, making them an interesting addition to a reef aquarium with a focus on diversity and naturalism.

Care

Caring for Chiton affinis in a home aquarium requires a stable environment with plenty of live rock and algae for grazing. They are hardy creatures that can adapt to a range of water conditions but prefer strong water movement and access to a variety of microalgae. It's important to ensure that the aquarium does not have predatory fish or invertebrates that might harm these chitons.

Reproduction

Chitons, including Chiton affinis, reproduce by releasing sperm and eggs into the water column, where fertilization occurs externally. In the aquarium, breeding is rare, but with a large, well-established system and multiple individuals, hobbyists may observe spawning behavior.

Habitat

Chiton affinis is typically found in the intertidal to subtidal zones, often in areas with strong wave action. They are adept at navigating rocky surfaces and can often be found in crevices or under rocks during low tide. In the aquarium, they will appreciate a setup that mimics these conditions with plenty of hiding places and surfaces to explore.
