Description
The Thornback Cowfish is a distinctive marine fish characterized by its box-like body, small fins, and prominent thorn-like spines on its back and sometimes above its eyes. It has a unique swimming style and can release a potent toxin (ostracitoxin) when stressed, which can be lethal to other tank inhabitants. This species requires a well-established aquarium with stable water parameters.
