What Does the Tigerfish Look Like?
When they are young, tigerfish are shiny silver. They have thin, dark stripes that go across their body. Their body is long and gets narrower at both ends, like a torpedo!
As these fish grow bigger, their color changes to a bronze shade. The stripes they had when they were young start to fade away. Their bottom fins and tail fins often have a bit of a red-orange color, which looks really neat. There's also a small, soft fin on their back called an adipose fin, which is usually gray or black.
This fish can grow quite large! It can reach a length of about 86 centimetres (34 in) from its snout to the end of its tail. That's almost as long as a baseball bat!
Where Do Tigerfish Live?
The tigerfish lives in many different places across Africa. You can find them all the way from Senegal in the west to Ethiopia in the east. They are especially common in the famous Nile River.
In Northeast Africa, they swim in river systems like the Ghazal and Jebel in Sudan. They also live in the Baro River in Ethiopia. In Western Africa, you can find them in countries like Chad. They also live in major rivers such as the Niger/Bénoué, Volta, Senegal, and Gambia.
Tigerfish Home and Habits
Tigerfish are freshwater fish, meaning they live in rivers and lakes, not the ocean. They are known as demersal fish, which means they often hang out near the bottom of the water. They are also potamodromous, which means they migrate (travel) within freshwater systems, usually to find good places to lay their eggs.
These fish really like open water areas where they have lots of space to swim and hunt. They are predators, which means they hunt other animals for food. Their main diet includes other fish and shrimps. Smaller tigerfish, especially young ones, also enjoy eating aquatic insects that live in the water.
How Are Tigerfish Doing?
Right now, the tigerfish is quite common in most of the places it lives. There aren't any big, widespread threats that are making their numbers drop quickly.
However, some areas are working to protect them. For example, Ghana has rules in place to help conserve these fish. One possible problem for tigerfish is overfishing, which means too many fish are caught. Other potential threats include deforestation (when forests are cut down, which can affect rivers) and pollution (when harmful things get into the water).
Scientists are still working to learn more about how many tigerfish there are and exactly where they all live. It's important to keep their homes healthy, so sometimes efforts are needed to maintain and restore their habitats. This helps make sure these amazing fish can keep swimming strong for a long time!
