Is the Scissortail Rasbora suitable for beginners?

Yes — it's considered a beginner-friendly fish thanks to its hardiness and tolerance for typical aquarium conditions. That said, basic water quality maintenance and regular water changes are still important.

Can it be kept with other fish?

Its peaceful temperament makes it easy to combine with similarly sized, calm-natured tankmates. It's best to avoid pairing it with very small fish or aggressive species.

How big does it grow?

It can reach up to about 13 cm. Actual growth rate and final size vary depending on the individual fish and its care.

How many should be kept together?

Since it's a natural schooling fish, it's best to keep a group of several or more together. Too few individuals can make them skittish and less likely to display their natural schooling behavior.

Why does it open and close its tail like scissors?

The scissor-like motion it shows while resting is a natural, species-specific behavior. It isn't a sign of poor health, so there's no need to be concerned about it.

Scissortail Rasbora

The Scissortail Rasbora is a medium-sized schooling fish known for its silvery body and the bold black-and-white bands marking the upper and lower lobes of its tail fin. Its name comes from a distinctive habit: when at rest, it opens and closes its forked tail in a scissor-like motion. Calm-tempered and rarely aggressive, this hardy fish adapts well to typical aquarium conditions, making it a solid choice for anyone new to the hobby. As a natural shoaling species, keeping a good-sized group in a roomy tank brings out its schooling behavior at its best, and it mixes easily with other peaceful community fish.

About Scissortail Rasbora

A hardy, peaceful medium-sized rasbora with a silver body and a black-and-white banded tail, known for its scissor-like tail motion — an easy pick for community tanks.

7 things to know before welcoming a Scissortail Rasbora

1Tank size to plan for
Scissortail Rasboras can grow to around 13 cm, so give them a tank with enough open swimming space to match their size. This matters especially when keeping a group, since a cramped tank limits their natural schooling behavior.
2Best kept in a group
These fish are natural shoalers and tend to become skittish or hide when kept in very small numbers. Keeping a reasonably sized group lets you see their natural schooling behavior at its best.
3Peaceful and community-friendly
Scissortail Rasboras have a peaceful temperament and rarely bother other fish. They pair well with similarly sized, calm tankmates, making them a good fit for lively community aquariums.
4The scissor tail motion is normal
When resting, this fish opens and closes the two lobes of its tail like a pair of scissors — a natural, species-specific behavior, not a sign of illness.
5Hardy and beginner-friendly
This species is considered beginner-friendly and adapts well to typical aquarium conditions. That said, sudden shifts in water quality can still stress any fish, so make water changes gradually.
6Prepare the tank before arrival
Before bringing fish home, make sure the tank is fully cycled with a stable filter and established water parameters. Take time to properly acclimate new arrivals rather than releasing them straight into the tank.
7Daily health checks
Get in the habit of watching daily behavior — swimming pattern, appetite, and body color. If you notice unusual movement or changes like white spots, check water quality and the fish's condition promptly.
