General Description
The Yellow-dotted Butterflyfish, scientifically known as Chaetodon selene, belongs to the Chaetodontidae family. These fish are part of a closely related group known for their attractive patterns and colors, resembling Angelfish but lacking spines on each side of the head. They are part of a larger group that targets different types of corals, including soft corals like Zoanthus and various LPS corals. Their diet includes anemones, tubeworms, bristleworms, and small invertebrates.
Aquarium Suitability
The Yellow-dotted Butterflyfish is suitable for aquariums but requires care. They are generally peaceful but may exhibit aggression towards similar species, especially if not paired. These fish are known to be shy and docile, necessitating caution when housed with more aggressive tank mates. They should be provided with ample hiding spots among live rocks and fed a varied diet to thrive. Their ideal tank size is a minimum of 400 liters, with a well-established setup that allows for swimming space and grazing on algae-rich surfaces.
Care and Hardiness
These fish have an average hardiness level and prefer water conditions with a pH of 8.1-8.4, a specific gravity of 1.020-1.025, a temperature range of 22.2-25.6°C, and a carbonate hardness of 8-12 dKH. Maintaining a stable and clean aquarium environment is crucial for their well-being. Yellow-dotted Butterflyfish must be provided with a varied diet that includes macroalgae, microalgae, small crustaceans, and zooplankton to ensure their nutritional needs are met.
Reef Suitability
The Yellow-dotted Butterflyfish is not considered reef-safe due to its tendency to nibble on clams, including Tridacna species, and feed on tubeworms. Therefore, caution is advised when keeping them in reef aquariums with sensitive coral species.
Aquarium Setup
When setting up the aquarium for Yellow-dotted Butterflyfish, it is essential to include plenty of live rocks with hiding places to mimic their natural habitat. Providing a well-run tank with sufficient algae for grazing is recommended. Supplementing their diet with algae-rich foods like Spirulina is crucial if natural algae sources are insufficient.
Behaviour
These fish are mostly peaceful but can display aggression towards similar species, particularly if not in a mated pair. Yellow-dotted Butterflyfish are known for their shy and docile nature, which underscores the importance of creating a stress-free environment in the aquarium.
Feeding and Diet
In captivity, Yellow-dotted Butterflyfish should be fed a diet consisting of macroalgae (such as seaweed or nori), microalgae (e.g., Spirulina), small crustaceans (like krill and mysis), and zooplankton (including cyclops and pods). Ensuring a varied diet rich in nutrients is vital to promoting the health and vibrancy of these fish.
Habitat and Distribution
These fish are native to the Western Pacific region, with recorded sightings in areas such as West New Guinea, Indonesia, Papua New Guinea, Taiwan, and Japan. Their natural habitat includes coral reefs where they can feed on a variety of invertebrates and corals.
