Longhorn Cowfish: A Whimsical & Unique Aquarium Fish

The Longhorn Cowfish (Lactoria cornuta) is a captivating and truly one-of-a-kind species that adds a touch of whimsical charm to any marine aquarium. Its stunning appearance features a distinctive box-shaped body with a vibrant yellow or tan coloration and a pair of prominent "horns" that protrude from its head. This peaceful and slow-moving fish is a gentle giant in a fish-only with live rock (FOWLR) tank, where its quirky personality and unique shape make it a captivating centerpiece.

Why the Longhorn Cowfish is a Great Choice:

• Unforgettable Appearance: Its unique body shape and horns make it a conversation starter and a memorable inhabitant.
• Peaceful Temperament: It is a non-aggressive species that coexists well with other peaceful and semi-aggressive tank mates.
• Hardy: When properly cared for, the Longhorn Cowfish is a very hardy and resilient species.
• Reef-Safe (with caution): While it will not harm corals, it may nibble on tube worms and other small invertebrates.

Important Note: When stressed, the Longhorn Cowfish can release a potent toxin that can be lethal to other fish in an enclosed aquarium. It is crucial to provide a stress-free environment and avoid sudden water parameter changes.
