Long Horn Cowfish

About this fish

Long Horn Cowfish is a saltwater fish for the home aquarium, sold under the scientific name Lactoria cornuta. As a rabbitfish-type grazer, it’s typically valued for its appetite for algae, which can help support a cleaner look on live rock and aquascape. In a well-prepared reef-safe style setup, it can also be a good addition for aquarists who want an active, algae-focused fish and are able to provide a stable environment and calm tankmates.

Features:

• Often described as a hardy grazer and commonly helps keep rockwork cleaner by eating algae
• Generally peaceful with other fish when tankmates are compatible
• Can release a toxin into the water when stressed or dying, so stability and careful handling matter
• Venomous fin spines are a safety concern—use caution when working in the tank
• Does best with a large, stable tank and open swimming space
• Feed an herbivore-focused routine such as algae sheets, seaweed, and herbivore pellets, supplemented with frozen foods
• Acclimate slowly and allow it a quiet settling spot after arrival to reduce stress
