Burrow's Chiton (Cryptoplax larvaeformis) – Complete Care Guide

General Information

The Burrow's Chiton (Cryptoplax larvaeformis) is a fascinating marine mollusk belonging to the class Polyplacophora. Unlike most chitons, which have a rigid, armor-like appearance, this species is elongated and worm-like, giving it a unique and somewhat misleading appearance. Its body is covered by a leathery girdle that conceals its eight shell plates, a characteristic feature of chitons. Found in shallow waters, it inhabits crevices and burrows in rocky substrates, which provide it with protection from predators and strong currents.

This species is not commonly kept in home aquariums but is occasionally sought after by enthusiasts interested in unique and cryptic invertebrates. Its ability to blend into its environment and its unusual appearance make it an intriguing addition to specialized marine setups.

Care

Burrow's Chiton is a hardy species but requires a well-established aquarium with plenty of live rock and crevices to mimic its natural habitat. It thrives in stable water conditions and prefers subdued lighting, as it is primarily nocturnal and avoids bright environments. This species is best suited for aquarists with some experience in maintaining marine invertebrates.

To ensure its well-being, provide a tank with ample hiding spots and a substrate that allows it to burrow or cling to surfaces. Avoid housing it with aggressive tank mates that may disturb or prey on it.

Diet and Feeding

In the wild, Cryptoplax larvaeformis grazes on algae and biofilm found on rocks and other surfaces. In captivity, it can be fed a diet of algae wafers, nori, and other plant-based foods. Supplementing its diet with natural algae growth in the tank will help keep it healthy and active.

Feed it sparingly, as overfeeding can lead to water quality issues. Observing its grazing behavior will help determine if additional food is necessary.

Behavior and Compatibility

Burrow's Chiton is a peaceful and reclusive species, spending most of its time hidden in crevices or burrowed into the substrate. It is non-aggressive and poses no threat to other tank inhabitants, making it an excellent choice for community tanks with other peaceful species.

Due to its cryptic nature, it may go unnoticed for long periods, emerging primarily at night to graze. This behavior makes it a fascinating species for aquarists who enjoy observing nocturnal marine life.

Health and Common Issues

This species is generally hardy when provided with stable water conditions and a suitable habitat. However, it is sensitive to poor water quality and sudden changes in parameters. Regular water changes and monitoring are essential to its health.

When acquiring a Burrow's Chiton, look for individuals with intact girdles and active grazing behavior. Avoid specimens that appear lethargic or have visible damage to their body.

Habitat

Burrow's Chiton is native to the Indo-Pacific region, where it inhabits intertidal zones and shallow waters. It is commonly found in rocky areas with plenty of crevices and burrows, which it uses for shelter. Its natural environment is characterized by moderate water flow and abundant algae growth, providing it with both protection and food.

In captivity, replicating these conditions is key to its success. Provide a tank with live rock and a substrate that mimics its natural habitat, ensuring plenty of hiding spots and surfaces for grazing.
