Care
Caring for Halgerda batangas requires a well-established reef aquarium with stable water conditions. They are sensitive to high levels of nitrates and copper-based medications. It is crucial to provide a tank with plenty of live rock and a suitable substrate for them to explore and forage. Since they feed on sponges, it's important to ensure a continuous food source, which can be challenging in a home aquarium.
Reproduction
Like many nudibranchs, Halgerda batangas is a hermaphrodite, possessing both male and female reproductive organs. They can lay ribbons of eggs, which are often deposited on the substrate or on the aquarium glass. The larvae that hatch are planktonic before settling down and metamorphosing into their adult form.
Habitat
Halgerda batangas is typically found in the tropical waters of the Western Pacific, including the Philippines. They are often observed on or near coral reefs, where they feed on specific types of sponges. In the wild, they can be found at various depths, often ranging from shallow waters to deeper reef slopes.
