This amphibious goby has bulging eyes set high on its head and a grey-brown body flecked with blue spots, with bright blue-edged dorsal fins it raises when displaying. Keepers love watching it skip across mud and climb roots out of the water, breathing air through its moist skin and gill chambers.

Breeding
In the wild males dig mud burrows where eggs are laid and guarded in an air pocket. Captive breeding is very rarely achieved because the tidal mudflat conditions are hard to recreate.
Good to know
Although often sold as a freshwater fish, it needs brackish water and a large land area, and will die if kept fully submerged. Males are territorial and will fight, and a tight lid is essential as they climb and jump.
