Teardrop Butterflyfish

Geographical Origin and Habitat: Tropical Indo-Pacific, distributed from East Africa to the Hawaiian and Marquesan Islands. Inhabits shallow lagoons and seaward reefs rich in soft corals and sponges.

Taxonomy and Morphology: Member of the family Chaetodontidae. Features a deep, disc-like body shape with a robust jaw and teeth specialized for grazing on tough invertebrates.

Social Behavior: Peaceful and active species. Found in pairs or small groups. Unusually robust compared to other butterflyfish, known to consume sponges and soft corals.

Coloration and Sexual Dimorphism: Silvery-white body background, transitioning to yellow near the margins. Marked with a large, round black spot on the upper flank that trails downward like a tear.

Aquarium Setup: Requires a mature marine aquarium of at least 350 liters with plenty of live rock to provide hiding spots and natural grazing surfaces.

Diet and Feeding: Omnivorous. Feeds on sponges, coral polyps, and benthic algae. In captivity, accepts high-quality flakes, pellets, frozen brine shrimp, mysis, and spirulina.

Water Quality: Standard marine parameters: temperature 22-27 °C, pH 8.1-8.4, and salinity 1.020-1.025 with efficient filtration and moderate water movement.

Compatibility and Cohabitation: Highly peaceful. Not reef safe as it nips at stony corals. Best kept with quiet, non-aggressive species in a fish-only setup.

Aquarium Breeding: Spawning in home aquariums is undocumented. Pelagic spawner. Eggs and larvae drift in the ocean column before settling onto reefs.

Risks and Diseases: Once acclimated, it is relatively hardy. Susceptible to marine ich (Cryptocaryon) and stress. Ensure the aquarium is fully cycled.
