What makes the Greater Scissortail a popular choice among aquarists?

Its unique coloration, active behavior, and compatibility with other peaceful fish make it a standout addition to community aquariums.

Is the Greater Scissortail suitable for beginner fishkeepers?

Yes, with proper care and attention to its environmental needs, it can be a rewarding species for both novice and experienced aquarists.

Care and Environment

Providing a suitable environment is crucial for the health and well-being of the Greater Scissortail. A minimum tank size of 114 liters is recommended to accommodate their active swimming behavior. For optimal conditions, especially when keeping a group, a larger tank of at least 200 liters is ideal.

Water parameters should be maintained within the following ranges:

• Temperature: 20–26°C
• pH: 5.0–7.5
• Hardness: 2–10 dGH

Efficient filtration is essential to keep the water clean and well-oxygenated. Incorporating a gentle current can mimic their natural riverine habitats. Lighting should be subdued to replicate the dimly lit environments they are accustomed to.

When it comes to feeding, the Greater Scissortail is omnivorous and accepts a variety of foods. A balanced diet should include high-quality flake or pellet foods supplemented with live or frozen options like bloodworms, brine shrimp, and daphnia. Feeding once or twice daily is sufficient.

Tank decor should provide both open swimming spaces and hiding spots. Incorporating plants such as Java fern and Anubias, along with driftwood and rocks, can create a naturalistic environment. A darker substrate can enhance their coloration and mimic their native riverbeds.

It's important to note that the Greater Scissortail is known to be an adept jumper. Therefore, a tightly fitting lid is essential to prevent escape.

How often should I feed my Greater Scissortail?

Feeding once or twice daily with a varied diet ensures they receive adequate nutrition.

Can I keep a single Greater Scissortail in my tank?

While possible, they thrive best in groups of at least six, as they are naturally schooling fish.

Origin and Habitat

The Greater Scissortail is native to Southeast Asia, specifically found in regions such as Peninsular Malaysia, Borneo, and Sumatra. In the wild, they inhabit a variety of freshwater environments, including fast-flowing forest streams with sandy or rocky substrates and sluggish blackwater habitats like peat swamp rivers. These habitats are often characterized by submerged vegetation and woody debris, providing ample hiding spots and foraging opportunities.

What type of water bodies do Greater Scissortails prefer?

They are adaptable and can be found in both fast-flowing streams and slow-moving blackwater rivers.

Are they commonly found in heavily vegetated areas?

Yes, their natural habitats often include submerged plants and woody debris, offering shelter and feeding grounds.

Temperament and Compatibility

The Greater Scissortail is a peaceful and active species, making it well-suited for community aquariums. They are schooling fish and should be kept in groups of at least six to promote natural behavior and reduce stress. Suitable tank mates include other peaceful species such as tetras, danios, gouramis, and bottom dwellers like corydoras catfish. It's advisable to avoid housing them with very shy or slow-moving fish, as their active nature might cause undue stress to more timid species.

Can Greater Scissortails be kept with larger fish?
