Description
The 'O‘opu 'alamo'o is a unique Hawaiian freshwater goby known for its striking coloration, with males displaying a dark body and a vibrant orange-red tail, often tipped with blue. These amphidromous fish inhabit fast-flowing, high-oxygen streams, using a specialized sucking disc to cling to rocks. They are primarily herbivorous, grazing on algae and diatoms, but will also consume small invertebrates.
