What Does a Blackline Rasbora Look Like?
The blackline rasbora has a sleek, silver body. It has a cool dark brown or black stripe along its side. This stripe goes from its gills all the way to its tail fin. Right above this dark line, there's a shiny gold stripe. Its tail fin is a bright, eye-catching red. Unlike some other similar fish, its red tail doesn't have any black spots.
It's hard to tell the difference between male and female blackline rasboras. They look very similar. However, adult females are usually a little bit bigger than the males. These fish can grow to be about 2.5 inches (64 mm) long. That's about the length of your thumb!
Where Do Blackline Rasboras Live?
Blackline rasboras like to swim in calm waters. You can find them in ponds, small ditches, and canals. They also live along the edges of reservoirs. They usually stay in water that is about 2 metres (6 ft 7 in) deep or less.
These fish prefer water that is slightly acidic to neutral. This means the pH level should be between 6.5 and 7.0. They also like water that isn't too hard. The temperature of the water they live in is usually between 22 and 26 °C (72 and 79 °F). This is a comfortable, warm temperature for them.
Keeping Blackline Rasboras in Aquariums
The blackline rasbora is a very popular aquarium fish. They are great for people who enjoy keeping fish as pets. They like tanks with slow-moving water. They also love tanks that have lots of plants.
These fish are true schooling fish. This means they almost always swim together in a tight group. You will often see them racing back and forth in the middle and upper parts of the aquarium. They are strong and peaceful fish. This makes them good tank mates for other calm fish. They can live happily with fish like loaches, small and large tetras, livebearers, plecos, and rainbowfish.
