General Description
The Mirror Butterflyfish, scientifically known as Chaetodon speculum, belongs to the Chaetodontidae family. These fish are part of a group called a "complex" due to their striking similarities. Distinguishing features are crucial, as some variations in color and patterns can signify different needs within the species. Originating from the Indo-Pacific region, they span from Indonesia to Japan, south to the Great Barrier Reef and Papua New Guinea, and have been reported in areas such as Mauritius, Madagascar, and Reunion.
Aquarium Suitability
The Mirror Butterflyfish requires a seasoned aquarist with meticulous preparation and attentive care. These fish possess a docile temperament, preferring to be solitary in a tank due to their shy nature. They call for a spacious aquarium to accommodate their swimming habits and necessitate ample hiding spots among live rocks. Due to their specific dietary needs, providing a varied diet is crucial for their well-being.
Demands, Care, and Hardiness
Being of average hardiness, Mirror Butterflyfish can face challenges in captivity due to their specialized diet of coral polyps. It's paramount to ensure they have access to live corals, mussels, and zooplankton to acclimatize them to alternative foods. Despite efforts, a noteworthy percentage may struggle to adapt, leading to a shortened lifespan in captivity. Healthy specimens should be chosen to avoid potential issues like parasite infections.
Reef Suitability
Mirror Butterflyfish are deemed incompatible with reef environments due to their tendency to nibble on clams, including Tridacna species, and their preference for tubeworms, which can jeopardize the delicate balance of a coral reef setup.
Aquarium Setup
When setting up an aquarium for Mirror Butterflyfish, it is crucial to create an environment that mirrors their natural habitat. Incorporate ample live rocks for hiding places and provide enough space for them to swim freely. Maintaining stable water conditions with a pH of 8.1-8.4, a temperature range of 22.2-25.6°C, a specific gravity of 1.020-1.025, and a carbonate hardness of 8-12 dKH is essential.
Behaviour
Mirror Butterflyfish exhibit a mostly peaceful demeanor but may display aggression towards similar species, hence caution is advised when housing them together. Their shy and docile nature necessitates a tranquil tank environment to thrive.
Feeding and Diet
Feeding Mirror Butterflyfish can be challenging as they predominantly consume coral polyps. To ensure their nutritional needs are met, offering live corals, mussels, and zooplankton is vital. Acclimating them to alternative foods may require patience and persistence to sustain their health in captivity.
Dimorphism
Not Applicable.
Habitat and Distribution
Mirror Butterflyfish are native to the Indo-Pacific region, spanning from Indonesia to Japan and southwards to the Great Barrier Reef and Papua New Guinea. Additionally, they have been sighted in regions like Mauritius, Madagascar, and Reunion.
