Malacoctenus triangulatus is a charming blenny species prized for its distinctive triangular markings and engaging behaviour. This small marine fish is well-suited to reef aquariums and is appreciated by hobbyists for its peaceful temperament and relatively straightforward care.
Care Level: This species is considered to have a moderate care level, making it suitable for aquarists with some marine experience.
Temperament and Compatibility: Malacoctenus triangulatus is generally peaceful and can be kept with other non-aggressive fish species. It is territorial towards conspecifics or similar blennies, so caution is advised when housing multiple individuals.
Diet: This blenny is carnivorous and thrives on a varied diet including live or frozen meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood. Supplementing with high-quality marine pellets or flakes is beneficial.
Tank Requirements: A minimum tank size of 75 litres (20 gallons) is recommended to provide adequate swimming space and territory. The aquarium should feature plenty of live rock for hiding and grazing.
Lighting and Water Flow: Standard reef aquarium lighting is suitable. Moderate water flow mimicking natural reef conditions is ideal to maintain water quality and oxygenation.
Placement: Provide ample rockwork and crevices to allow natural behaviour such as perching and hiding. This also helps reduce stress and territorial disputes.
Reef Compatibility: Reef safe with caution. While generally safe with corals and invertebrates, monitor interactions as some blennies may nip at sessile invertebrates.
Origin: Not Provided.
Maximum Size: Approximately 7 cm (2.8 inches).
