Common name: long-tailed sea hare

General information

The Blue-Green Sea Hare, scientifically known as Stylocheilus longicauda, is a captivating marine gastropod mollusk that adds a unique touch to the reef aquarium. This species is known for its striking blue-green coloration and elongated tail, which distinguishes it from other sea hares. They are not only admired for their beauty but also for their algae-eating habits, making them beneficial for controlling algae growth in the aquarium.

Care

Stylocheilus longicauda requires an established aquarium with plenty of macroalgae to graze on. They are sensitive to water quality, so maintaining pristine conditions is crucial. It's important to ensure that there is a continuous supply of algae; otherwise, supplemental feeding with seaweed or prepared algae-based foods may be necessary. They are peaceful creatures and should be housed with non-aggressive tank mates.

Reproduction

Sea hares are hermaphrodites, possessing both male and female reproductive organs. They can form mating chains where one individual acts as a male to the one in front and as a female to the one behind. In the aquarium, breeding is rare, but if conditions are right, they may lay long strings of eggs, which develop into free-swimming larvae.

Symbiosis

While not involved in the classic symbiotic relationships seen with corals and fish, sea hares do play an important role in the ecosystem by controlling algae and providing a food source for other animals. Their presence can help maintain a balance in the aquarium's micro-environment.

Habitat

Stylocheilus longicauda is typically found in shallow, tropical waters where there is an abundance of algae. They prefer reef-associated habitats with plenty of hiding spots and grazing areas.
