Odonus niger | XL

The Odonus niger, also known as the Purple Tang or Blue Velvet Triggerfish, is a visually captivating species prized for its vibrant purple-blue colour and dynamic swimming behaviour. This extra large specimen is ideal for experienced marine aquarists with spacious tanks.

Temperament and Compatibility: Odonus niger is generally semi-aggressive and territorial, especially in confined spaces. It can coexist with other robust fish species but may show aggression towards smaller or more passive tankmates. Avoid housing with very small or timid fish to reduce stress and potential conflicts.

Diet: This triggerfish is omnivorous, thriving on a varied diet including meaty foods such as mysis shrimp, brine shrimp, chopped seafood, and high-quality marine pellets or flakes. Supplementing with algae or seaweed-based foods supports their natural grazing behaviour and enhances colouration.

Tank Requirements: Due to its size and activity level, a minimum tank size of 250 litres (approximately 65 gallons) is recommended to provide ample swimming space and reduce territorial behaviour. The aquarium should include plenty of live rock for hiding and grazing, as well as open swimming areas.

Water Parameters and Environment: Maintain stable marine conditions with a temperature between 24-27°C, salinity of 1.020-1.025 SG, and pH of 8.1-8.4. Moderate water flow is preferred to mimic natural reef environments without causing excessive stress.

Reef Compatibility: With Caution. While Odonus niger may occasionally nip at corals or sessile invertebrates, individual behaviour varies. It is best suited to fish-only or mixed reef tanks with hardy corals and invertebrates.

Overall, the extra large Odonus niger is a stunning addition for advanced hobbyists seeking a bold and active triggerfish. Proper tank size, diet, and compatibility considerations are essential for long-term health and vibrant colouration.
