Scissortail Rasbora


Tank Setup

Tank size

Scissortail Rasbora needs a minimum tank size of 20 gallons. Remember, a larger tank is always better for fish health and happiness.


Moderate lighting is ideal for Scissortail Rasboras. I once noticed that using too bright lights stressed my fish, so keep it balanced!

Filtration & Aeration

Proper filtration and aeration are essential. A simple sponge filter or hang-on-back filter would suffice.


Maintain water temperature between 72°F to 78°F. I use an adjustable heater in my tank to achieve the desired temperature.


Scissortails prefer a sandy or fine gravel substrate that closely resembles their natural habitat.


These fish enjoy hiding spots like driftwood, rocks, or caves. Remember, they are schooling fish, so balance open swimming areas with decorations.


Live plants like Java moss, Anubias, and Amazon swords provide both aesthetic and functional benefits for Scissortail Rasboras in your tank.

Water Quality

Water Temperature

Scissortail Rasboras thrive in water temperatures between 72-79°F (22-26°C). I remember when my tank heater malfunctioned, and I noticed the fish lethargic and stressed. Timely intervention restored their spirits.

Water pH

Maintaining a stable pH is crucial for the well-being of Scissortail Rasboras. They prefer a pH range of around 6.0-7.5. Tip: Use a reliable test kit to monitor pH levels regularly.

Water Hardness

  • The ideal water hardness for Scissortail Rasboras is 2-15 dGH.
  • In very soft water, they may not thrive as well.
  • Slightly harder water may be tolerable, but consistency matters more.

Water Changes

Consistent water changes are necessary for Scissortail Rasboras:

  • Perform 25-30% water changes biweekly.
  • Use a gravel vacuum to remove waste and debris.

By ensuring optimal water quality, your Scissortail Rasboras will remain active and healthy.

Tank Maintenance

Maintaining a clean and healthy environment is essential for Scissortail Rasboras. Regular water changes are the key to keeping them happy.

In my experience, changing 20-30% of the tank water weekly is effective. Keep the temperature between 72-79°F and ensure adequate filtration.

You should also monitor the pH and ammonia levels. Scissortail Rasboras prefer pH levels between 6.0-7.5. Ammonia should be as close to 0 ppm as possible.

Use of live plants in the tank is beneficial. It not only adds a natural touch, but also keeps the water clean and provides hiding spaces for the fish.

Remember to clean the tank glass to avoid algae accumulation. I like using a magnetic algae cleaner as it minimizes stress on the fish.

Feed your Scissortail Rasboras a balanced diet with varied nutrients. Try offering them high-quality flakes, pellets, or frozen foods like brine shrimp or daphnia. Watching their excitement during feeding time is one of my favorite parts of fishkeeping!

In summary, staying on top of tank maintenance ensures a healthy and thriving environment for your Scissortail Rasboras. Happy fishkeeping!

Tank Mates

Compatible Fish Species

In my experience, Scissortail Rasboras get along well with a variety of small, peaceful fish species. Some great tank mates for Scissortail Rasboras include:

  • Tetras: They are small, peaceful fish that make excellent community species.
  • Guppies: Their vibrant colors complement the Rasboras’ sleek appearance.
  • Corydoras: These bottom-dwelling fish have a similar temperament and won’t compete for food or territory.

Incompatible Fish Species

However, there are certain fish species that Scissortail Rasboras don’t mix well with. I had a negative experience when I tried to introduce a few larger, more aggressive species into the tank. Here are a few examples of incompatible companions:

  • Cichlids: These aggressive fish can stress out Scissortail Rasboras and even prey on them.
  • Oscars: Like Cichlids, Oscars are territorial and may attack Rasboras.
  • Large catfish: Some species of catfish grow large enough to eat small Rasboras


What To Feed

Scissortail Rasboras are omnivorous fish that eat a variety of foods in their natural habitat. In an aquarium setting, it’s best to provide them with a balanced diet. You can feed them:

  • High-quality flake food: This can form the base of their diet, providing essential nutrients.
  • Frozen or live foods: Brine shrimp, daphnia, and bloodworms are great options for protein intake.
  • Vegetables: Blanched spinach or cucumber can supplement their diet with additional vitamins.


It’s crucial to feed your Scissortail Rasboras regularly to keep them healthy and vibrant. I recommend feeding them twice a day—once in the morning and once in the evening.


  • Feed your fish small amounts to prevent overfeeding—give only as much as they can consume within a few minutes.
  • Observe their eating habits and adjust the portion size accordingly to ensure they’re getting enough nutrition without fouling the water.
  • Occasionally mix up their diet with different food options to mimic their natural feeding behaviors and prevent boredom.

I once had issues with finicky eaters in my Scissortail Rasbora school. By introducing a few live food options, I saw a noticeable improvement in their appetite and overall well-being.

Common Diseases


Scissortail Rasboras are generally healthy fish, but they can still suffer from common diseases such as Ich (Ichthyophthirius multifiliis) and fin rot.


Ich is easily recognizable by tiny white spots on the fish’s body. They may also display unusual behavior like rubbing against tank surfaces. As for fin rot, affected individuals will have ragged, deteriorating fins and may lose color.


To treat Ich, increase the water temperature to 86°F for about a week, use aquarium salt, and consider over-the-counter medications. For fin rot, water changes and antibacterial medications are recommended.


A focus on prevention is key to Scissortail Rasbora care. Ensure the aquarium is clean, well-maintained, and not overcrowded to minimize stress. In my own experience, I’ve found that regular water changes and maintaining high water quality help keep my Rasboras healthy and disease-free.

Signs of a Healthy Fish

When it comes to Scissortail Rasbora care, it’s important to recognize the indicators of a healthy fish. A vibrant appearance is a prime sign. Look for bright colors and clear, unclouded eyes.

Another indication of health is an active swimmer. Scissortail Rasboras should swim gracefully, with a steady back-and-forth movement.

Take note of their appetite. These fish should be eager to eat when presented with food. Be cautious; overfeeding can lead to health problems.

A healthy Scissortail Rasbora should have no physical abnormalities. Check for any swelling, discolored patches, or injuries.

When I started keeping Scissortail Rasboras, I observed how they interacted within their community. Healthy fish are social and should interact positively with their tankmates.

Regular monitoring is vital. Keeping a close eye on your Scissortail Rasboras will help you quickly spot any changes in appearance, behavior, or health.

Bear in mind these signs to ensure the well-being of your Scissortail Rasboras and enjoy witnessing their captivating movements and colors.

Signs Your Fish is Sick

One day, I noticed my Scissortail Rasbora swimming strangely. That was when I decided to look into the signs of a sick fish. Here are some common signs to watch for:

  • Loss of appetite: If your fish isn’t eating, this might be an indicator that something is wrong. Healthy fish should be eager to eat.
  • Unusual swimming patterns: Fish that swim erratically or struggle to maintain balance could be dealing with health issues.

Some health issues can be recognized by visual cues:

  • Discolored scales: Changes in color, such as dull, faded, or discolored scales could indicate underlying problems.
  • Clamped fins: Fish with their fins tightly clamped to their body can be a sign of distress or illness.
  • Bulging eyes: This could signify serious health concerns, such as infections or parasites.

Furthermore, there are specific signs for some prevalent diseases:

  • Ich: Tiny white spots on the fish’s body, resembling grains of salt, indicate a parasite infestation.
  • Fin rot: Deteriorating, frayed, or discolored fins can be a sign of a bacterial infection.

Regularly monitoring the health of your Scissortail Rasbora is essential. Early detection can help prevent the spread of diseases and facilitate treatment. Staying observant and proactive can help your fish thrive.


Breeding Setup

To breed Scissortail Rasboras, I recommend setting up a separate breeding tank with a sponge filter and plants like Java moss or spawning mops for the eggs to adhere to. The temperature should be kept at 78-80°F (26-27°C) and a lower water level of about 6 inches to encourage spawning.

How To Breed

Condition the adult fish with high-quality live or frozen foods to encourage breeding behavior. Afterward, introduce a pair or small group of males and females into the breeding tank. Keep an eye on them to observe any signs of courtship and spawning.


Once the eggs are laid, remove the adults to prevent them from eating the eggs. Maintain a stable temperature and monitor the water quality. The eggs will usually hatch within two to three days, and the fry will be free-swimming a few days later. At this point, you can start feeding them with infusoria or baby brine shrimp. Gradually increase the food size as they grow.

Remember my first successful Scissortail Rasbora breeding, the feeling of accomplishment and excitement was exhilarating. By following these simple steps and tips, I believe you too can breed and care for these fascinating fish in your own aquarium.
