Helmet Cowfish

Tetrosomus gibbosus

Reef Safe with Caution

The Helmet Cowfish, scientifically known as Tetrosomus gibbosus, is distinguished by its unique helmet-like structure and boxy body covered in bony plates. This species often exhibits a pale yellow to brown coloration with subtle patterns, contributing to its distinctive and appealing look. While it is generally peaceful, it should be monitored closely in reef tanks due to its sensitivity to water quality and potential to nip at corals and invertebrates. The Helmet Cowfish thrives in well-established aquariums with ample swimming space and hiding spots, making it a fascinating and visually striking addition to larger marine setups.

These fish are for saltwater aquariums only.
