Molluscs

Chelidonura inornata, commonly known as the blue opalescent sea slug, is a striking marine mollusc that showcases the intriguing diversity of underwater life. This species is easily recognizable due to its vibrant color patterns, often displaying hues of blue and green that shimmer under sunlight. The body is elongated and flattened, allowing it to glide gracefully over sandy and rocky substrates in its natural habitat.

This mollusc is predominantly found in the Coral Triangle, specifically around reef environments in Bali, Indonesia. It thrives in shallow waters, where it can be spotted among coral crevices and algae-covered rocks. Chelidonura inornata plays a significant role in the marine ecosystem as a herbivore, primarily feeding on algae, which contributes to the balance of the reef ecosystem.

Behaviorally, Chelidonura inornata is known for its fascinating locomotion, utilizing a foot that is adapted for smooth movement across various surfaces. They are generally solitary creatures but can be found in small groups when foraging for food. During daytime, they tend to remain hidden under rocks or within crevices, while at night, they are more active, showcasing their vivid colors to potential mates.

The natural history of Chelidonura inornata highlights its importance in the study of marine biodiversity, particularly in understanding the ecological roles of molluscs in coral reef systems. Their unique adaptations and behaviors make them a subject of interest for researchers and marine enthusiasts alike.

For aquarium importers and retailers, Chelidonura inornata requires specific care to thrive in captivity. The ideal water parameters include a temperature range of 24-28°C, a salinity of 32-35 ppt, and a pH level between 8.1 and 8.4. It is crucial to maintain stable conditions to prevent stress and ensure the health of these molluscs.

Feeding Chelidonura inornata is relatively straightforward, as they primarily consume algae and detritus. High-quality marine algae or herbivore pellets can be offered to meet their dietary needs. It is important to monitor their feeding habits and ensure they are receiving adequate nutrition without overfeeding, which can lead to water quality issues.

Compatibility-wise, these molluscs are best kept in a peaceful community tank with other reef-safe species. Avoid aggressive fish that may harass or prey on them. When introducing Chelidonura inornata to a new tank, gradual acclimation is essential to reduce stress. This can be achieved through drip acclimation over several hours. Additionally, a quarantine period of at least two weeks is recommended to prevent the introduction of potential pathogens into the main aquarium.

Chelidonura inornata is suitable for shipping, provided that appropriate measures are taken to ensure their survival during transit. Packing density should be moderate to allow for adequate oxygen exchange. Temperature sensitivity is a concern, so maintaining water temperatures between 24-28°C during shipping is crucial. There are currently no CITES restrictions on this species, making it easier for importers to acquire responsibly.
