Red Tail Rock Goby

Bold, colourful, and full of character — the Red Tail Rock Goby is a striking freshwater goby prized for its vivid red-orange tail and intricate body patterning. An active and personable bottom-dweller that brings both colour and personality to any cool-water or hillstream aquarium.

Overview

Appearance

The Red Tail Rock Goby displays a warm tan to olive body with intricate brown and red-orange spotting and banding, culminating in a vivid red-orange caudal fin that gives this fish its common name. Males are more intensely coloured, especially during breeding condition. Their fused pelvic fins form a suction disc that allows them to cling to rocks and navigate strong currents with ease.

Compatibility

Best kept with cool-water fish of similar size. Avoid housing with very small fish or shrimp. Males are territorial with each other — provide ample space and visual barriers if keeping multiple individuals.

The Red Tail Rock Goby is a bold and beautiful fish that brings vivid colour and engaging behaviour to any cool-water aquarium. A wonderful choice for goby enthusiasts and biotope aquarium keepers alike.
