Why We Like It:

Sleek, elegant, and constantly hovering in the water column, the Blue Gudgeon adds graceful movement and soft blue tones to peaceful reef tanks. Best kept in groups in larger systems, they create natural shoaling behaviour in open water. Completely reef safe and non-aggressive, but a tight-fitting lid is essential as they are prone to jumping when startled. A brilliant choice for adding flow and motion to open reef spaces.
