Scissortail Rasbora
Scissortail rasboras have a large forked caudal fin (tail fin), which gives these hardy rasboras their name. They are also called three-lined rasboras, even though the three colors are sometimes difficult to see on the tail fin. These fast-moving fish will grow to three inches and can handle mildly aggressive fish tanks. Maybe too fast and large for nano tanks, the scissortail rasbora is suitable for all other aquariums.

These fish are very active and add a lot of movement to the tank. The forked tail is striking and easy to spot. They’re peaceful and don’t bother other fish, even in a community tank. I’ve had them for six months and they’re still healthy and vibrant.

The colors are subtle, especially on the tail, but the movement is impressive. They do need a bit of space and a well-planted tank to feel comfortable. Good for medium-sized aquariums with other peaceful fish.

Easy to care for and very hardy. They thrive in a stable environment with moderate water parameters. I noticed they swim in groups, which makes the tank look lively and dynamic.
