- The Freshwater Mangrove Goby is a small freshwater fish that is found in the rivers and creeks of northern and eastern Australia, primarily in Queensland.
- It has a streamlined body with a pointed snout, a flattened head. The body coloration of this species can vary depending on their habitat and age, but they generally have a brownish-green or greyish-brown colour with darker stripes or spots along their sides.
- They are able to tolerate a wide range of salinities, which allows them to live in both freshwater and brackish water habitats.
- It is a carnivorous species, feeding primarily on small invertebrates such as shrimp, worms, and insect larvae.
- The breeding behaviour of the Freshwater Mangrove Goby is not well understood, but it is believed that they lay their eggs in small nests or burrows in the sand or gravel. The eggs hatch into larvae, which are carried out to sea by the tides and currents. The larvae eventually return to estuarine and freshwater habitats as juveniles.
- The Freshwater Mangrove Goby is able to breathe air through its skin, allowing it to survive in low-oxygen environments and even temporarily leave the water to escape predators.
- Their lifespan is estimated to be around 3-4 years.
The Freshwater Mangrove Goby can make an interesting and relatively easy-to-care-for aquarium fish. They are small in size, peaceful, and can be kept in groups or pairs in a suitably sized aquarium.
