The Desert Goby is native to Australia, being found in small pools, springs and streams in central Australia. Male gobies can grow to about 6cm, with the females being slightly smaller. If well cared for, Desert Gobies can live for up to 5 years if kept healthy and happy.
The Desert Goby has a short, rounded body with a large head and big wide mouth. They are yellow in colour. The front dorsal fin is blue and the other is black with a darker blue through it and a bright white edge. They will show a lot more colour during the breeding season.
Desert Gobies are hardy fish that can tolerate fresh water to quite high salinities due to the harsh and unstable environment in nature. They are best kept in small groups 4 females to 2 males. Desert Gobies like plenty of hiding spaces which can be provided by logs, rocks and plants. They inhabit the bottom of the tank and make a great addition to native species community aquariums.
Desert Gobies tolerate a wide range of water quality but prefer hard, alkaline water and benefit from the addition of a small amount of salt to the water. A pH between 7.0 and 8.0, a general hardness between 250 and 300ppm and temperatures 23 and 26°C are suitable.
Desert Gobies are omnivorous and feed on almost anything. In the aquarium, they can be fed frozen foods, such as brine, daphnia and frozen blood worms, as well as, small pellets and flake. A favourite food is live black worm.
Desert Gobies are compatible with other brackish fish and even fresh water species. Some common tank mates are Half Beaks, Scats, Monos, Bumble Bee Gobies, Rainbowfish.
Sexing the desert goby is very easy and it’s all about colour. The males lower jaw will be bright yellow and have a blue patch with a yellow margin on the first dorsal fin. The female on the other hand will be a lot duller and have clearer fins. They are relatively easy to breed but fecundity is low with a large female dropping up to 250 eggs. The male will then fan them with the female not really showing any interest.
