Chaetodon humeralis, commonly known as the small butterflyfish, is a visually striking addition to any marine aquarium. This species displays vibrant colours and distinctive markings that make it a favourite among experienced hobbyists.
Care Level: Moderate to advanced care is recommended due to its specialised dietary needs and sensitivity to water quality.
Temperament: Generally peaceful but can be territorial towards conspecifics or similar species. Best kept singly or as a mated pair in larger tanks.
Diet: Omnivorous with a preference for meaty foods such as mysis shrimp, brine shrimp, and specialised prepared diets formulated for butterflyfish. Supplement with algae-based foods to ensure balanced nutrition.
Tank Requirements: Minimum tank size of 150 litres (approximately 40 US gallons) is advised to provide ample swimming space and territories. A well-established aquarium with plenty of live rock is essential to support natural grazing behaviour and provide hiding spots.
Compatibility: Compatible with other peaceful fish species but avoid aggressive tank mates. Not reef safe as it may nip at corals and sessile invertebrates.
Water Parameters: Maintain stable marine conditions with temperature between 24-27°C, pH 8.1-8.4, and specific gravity 1.023-1.025.
With proper care, Chaetodon humeralis can thrive and become a captivating focal point in your marine aquarium.
