Manonichthys polynemus is a visually captivating dottyback species prized for its distinctive elongated fins and graceful swimming behaviour. This marine fish is best suited for intermediate to advanced hobbyists due to its specific care requirements and territorial nature.
Temperament and Compatibility: Generally semi-aggressive, Manonichthys polynemus can be territorial, especially towards conspecifics and similar-shaped fish. It is recommended to keep only one individual per tank or introduce it last to a community setup. Compatible tank mates include larger, robust species that can tolerate its assertiveness. Avoid housing with very small or timid fish.
Diet: This species thrives on a varied diet consisting of high-quality frozen or live foods such as brine shrimp, mysis shrimp, and finely chopped seafood. Supplement with specialised pellet or flake foods formulated for carnivorous marine fish to ensure balanced nutrition.
Tank Requirements: A minimum tank size of 75 litres (approximately 20 gallons) is advised to provide ample swimming space and territory. Maintain stable water parameters typical of reef aquaria: temperature 24-27°C, salinity 1.023-1.025 SG, pH 8.1-8.4. Moderate water flow and good filtration are essential to support health and water quality.
Reef Compatibility: With caution. While generally reef safe, Manonichthys polynemus may occasionally harass small invertebrates or peaceful fish. Monitor behaviour closely and provide plenty of hiding places using live rock or artificial décor.
Origin: Not Provided.
Maximum Size: Approximately 10 cm (4 inches).
