Care
One-spot Demoiselles are adaptable and can thrive in a variety of tank conditions, but they do best in well-established aquariums with plenty of live rock for hiding and grazing. They are omnivorous and will accept a wide range of foods, including flake, frozen, and live foods. It's important to maintain good water quality and stable parameters to keep these fish healthy.
Reproduction
Like many damselfish, the One-spot Demoiselle is known to breed in captivity. They lay their eggs on flat surfaces, where the male will guard and tend to them until they hatch. The fry can be raised on a diet of rotifers and later brine shrimp nauplii.
Habitat
The natural habitat of the One-spot Demoiselle ranges from shallow lagoons to coral-rich areas of the reef. They are commonly found at depths where light is abundant, which supports the growth of benthic algae and small invertebrates that make up their diet.
This species is distributed across the Indo-Pacific region, from East Africa to the central Pacific, including the Red Sea, Indian Ocean, and western Pacific Ocean.
