The banded rainbowfish (Melanotaenia trifasciata) is a beautiful and colorful fish. It's also known by other fun names like the Jewel rainbowfish or regal rainbowfish. You can find these fish living in the fresh waters of northern North Australia and Queensland.
These fish are quite striking! An adult banded rainbowfish can grow to about 12 to 15 centimeters long. They have a deep body, which means they are quite tall compared to their length. Like many rainbowfish, their colors can change depending on where they live. However, they all have a clear dark stripe along their side. Their top (dorsal), bottom (anal), and tail (caudal) fins are often bright red or yellow.

Banded Rainbowfish Behavior
The banded rainbowfish is a very active fish that loves to swim in groups, called a shoal. They usually swim near the surface or in the middle of freshwater areas.
How Banded Rainbowfish Reproduce
Banded rainbowfish breed throughout the year, especially during certain seasons. Male fish will often compete to attract females and claim their own space. They do this by swimming side-by-side, showing off their bright colors and extending their fins to look bigger.
After mating, a female can lay between 200 and 500 eggs. She attaches these tiny eggs to plants using sticky threads. Once the eggs are laid, the female leaves them. The male will then guard his territory, which includes the eggs, until they hatch. The eggs usually hatch about 6 to 7 days later.
Where Banded Rainbowfish Live and What They Eat
The banded rainbowfish can live in many different places. You might find them in rivers, calm lagoons, or slow-moving streams. They prefer areas where the water flows well. They also like places with sandy bottoms, lots of plants underwater, and submerged logs or branches.
What Do Banded Rainbowfish Eat?
Banded rainbowfish are omnivores, which means they eat both plants and animals. Most of their diet comes from small creatures like aquatic insects, spiders, and crustaceans (like tiny shrimp). They also munch on algae and even eat land insects that fall into the water, such as green ants.
The Name Melanotaenia trifasciata
The scientific name Melanotaenia trifasciata was given to this fish by Hialmar Rendahl in 1922. The word "Trifasciata" means "three-banded." However, live banded rainbowfish usually only have one main dark stripe. This difference happened because the first fish Hialmar described was a museum specimen. It had been preserved in a special liquid, which changed its natural pattern.
Keeping Banded Rainbowfish as Pets
Rainbowfish are fairly new to the world of aquarium hobbies. For a long time, only a small group of fish enthusiasts kept them. But now, they are much more popular! People love them because they are often very colorful, active, and easy to care for.
The banded rainbowfish is a great example of these traits. They are strong and peaceful fish that enjoy swimming in groups. This makes them a good choice for most peaceful community aquariums. They can also handle many different water conditions. Just like most rainbowfish, it's a good idea to have a lid on their aquarium because they are known to jump!
