- The Opal Cling Goby is found in freshwater streams and rivers in northeastern Australia
- They are known for their striking coloration, which includes a metallic blue-green back and bright orange fins.
- The Opal Cling Goby is named for its ability to cling to surfaces in fast-moving streams using a specialised suction cup-like structure on its ventral side.
- This fish species is also able to jump out of the water and cling to surfaces above the water line using its suction cup.
- Opal Cling Gobies are primarily herbivorous, feeding on algae and other plant matter.
- They are active during the day, and can often be seen clinging to rocks and other underwater structures. These fish are generally found in clear, fast-moving streams with rocky or gravelly substrates.
- Opal Cling Gobies have a unique reproductive behaviour, in which males build and defend nests made of algae and sand, and court females by performing elaborate dance-like displays.
- Females lay their eggs in the male’s nest, and the male guards and tends to the eggs until they hatch.
- Their lifespan is estimated to be around 2-3 years in the wild and up to 5 years in optimal conditions.
Opal Cling Gobies can make fascinating and unique aquarium fish, but they require a dedicated and experienced aquarist to provide the optimal care and environment they need to thrive.
