What Does the Clarence Galaxias Look Like?
The Clarence galaxias is a unique fish because it doesn't have scales. Its back is dark brown, with brown stripes and patterns going down its sides. Its belly is a lighter yellow-cream color. Adult Clarence galaxias usually grow to be about 12.5 to 14 centimeters (about 5 to 5.5 inches) long. They can weigh up to 20 grams, which is about the same as a few quarters.
Where Does the Clarence Galaxias Live?
The Clarence galaxias is a freshwater fish. This means it lives in lakes, swamps, and streams that are connected to lakes. It is found only in Tasmania, specifically in the Derwent River area. This includes a place called Clarence Lagoon. Scientists currently know of only seven groups of these fish that are able to reproduce.
Why is the Clarence Galaxias Endangered?
Even though you might find many Clarence galaxias in certain spots, this species is considered endangered by a group called the IUCN. This means it is at a high risk of disappearing forever. One of the biggest problems for the Clarence galaxias is other fish that have been brought into their habitat. These include brown trout and rainbow trout. These introduced trout compete with the galaxias for food and also hunt them.
How Does the Clarence Galaxias Behave?
The Clarence galaxias is a clever hunter. It likes to hide and wait for its prey, which is called being an "ambush predator." They might burrow into the mud or find a secret spot to wait. When there's plenty of food, they are very active and aggressive when they eat. These fish often rest on top of things like rocks, using their front fins to hold on. They are more active when it's evening.
They mostly eat live food, such as tiny insect larvae like mosquito larvae. They also eat small creatures called brine shrimp. Bloodworms are an exception; they can eat these even if they are frozen. When they swim, they move a bit awkwardly, seeming stiff in the middle of their body. However, they are surprisingly strong for their size. They have a thick front section, a big mouth, and large, fan-like fins.
