Food and feeding

Golden banded gobies should not be kept on a sole diet of flakes. Live or frozen brine shrimp, Daphnia, and white worms will provide them with a much more beneficial diet.

Origin

Asia; Golden banded gobies inhabit the saltwater swamps and stream estuaries of India, Thailand, Indonesia, Borneo, and Malaysia.

Sexing

Sexing can be difficult until the fish start spawning. The male will then lose his dark bands and take on a yellow body color.

Breeding

Brachygobius nunus breed better in a smaller aquarium with a salt mix of 2tsp/gallon. Provide caves or plant pots for the spawning to take place. The male will coax the female into the spawning site and she will deposit her eggs to the roof and sides. The male will guard the nest until the eggs hatch. Once the fry are free swimming, they can be fed on vinegar eels initially, as they grow, they will accept newly hatched brine shrimp.

Lifespan

The expected life span for Golden banded goby is 5-8 years.

Short description

The ventral fins of these fish have fused together to form a cup. This acts as a suction cup so that they can attach themselves to any surface. Golden banded gobies need to be kept in brackish conditions.
