Green Tiger Barb Species Profile and Identification

Green Tiger Barbs are highly popular freshwater fish in the world of aquariums. Recognized for their striking appearance, these tropical fish originated from Southeast Asia including Indonesia, Malaysia, Singapore, and Thailand.


Green Tiger Barbs have a distinct appearance that makes them easily recognizable:

  • A vibrant green body color with deep orange bands wrapping around it.

Green Tiger Barb Health Problems

Green Tiger Barbs are generally hardy fish, but they can still be affected by various health problems. By maintaining a clean tank and properly monitoring their care, you can prevent or treat these common issues.

Ichthyophthirius multifiliis (Ich): This is a common parasitic disease that causes white spots on the fish’s body and fins. To treat Ich, gradually raise the water temperature to about 86°F (30°C) and add medication designed for treating Ich according to label instructions.

Fin Rot: Caused by bacteria, this ailment results in frayed or disintegrating fins. Improve water quality by performing more frequent water changes, and use appropriate antibiotics to treat the infection.

Swim Bladder Disease: This condition is often due to overfeeding or constipation, causing the fish to have trouble swimming or float at the top of the tank. Feed them a high-quality diet, limit their meal quantities, and add green peas as a natural laxative to help restore their normal swimming pattern.

Skin Flukes: These are parasites that attach to the fish’s skin, causing them to rub against surfaces in an attempt to remove them. Treat by adding a broad-spectrum parasite treatment to the tank, following the instructions provided.

To stay proactive in preventing health problems, take the following steps:

  • Maintain a clean, well-filtered tank
  • Test water parameters regularly
  • Offer a high-quality, varied diet
  • Observe your Green Tiger Barbs daily for unusual behaviors or physical changes

By following these guidelines, you can keep your Green Tiger Barbs healthy and help them thrive in their aquarium environment.

Green Tiger Barb Tank Mates

When choosing tank mates for your Green Tiger Barbs, it is essential to select species that can comfortably coexist with these active, semi-aggressive fish. Here is a list of suitable and compatible tank mates:

  • Tetras: Choose peaceful, fast-swimming species like Rummy Nose Tetras, Ember Tetras, and Black Phantom Tetras.
  • Danios: Zebra Danios and Pearl Danios make great tank mates, thanks to their speed and adaptability.
  • Corydoras: These bottom-dwelling catfish, such as the Panda Cory and the Bronze Cory, complement Green Tiger Barbs nicely.
  • Loaches: Kuhli Loaches, Red-tailed Sand Loaches, and Dwarf Chain Loaches are some examples of compatible loaches.
  • Rainbowfish: Peaceful species like Neon Dwarf Rainbowfish and Boesemani Rainbowfish get along well with Green Tiger Barbs.
  • Gouramis: Dwarf Gouramis and Honey Gouramis are suitable tank mates due to their relatively calm temperament.
  • Other Barbs: Consider housing them with other barbs such as Cherry Barbs, Rosy Barbs, or Black Ruby Barbs.

However, it is important to avoid adding slow-moving, long-finned fish like Angelfish or Bettas, as Green Tiger Barbs may nip at their fins.

Additionally, large, aggressive fish like Oscars or Jack Dempseys might prey on the smaller barbs, so they are not recommended as tank mates.

Green Tiger Barb Breeding

Breeding Green Tiger Barbs can be a fun and rewarding experience for beginner fish keepers. To successfully breed these colorful fish, there are several factors you’ll need to consider to provide them with the ideal environment.

1. Separate breeding tank: It’s important to set up a separate breeding tank to ensure the best conditions for the Green Tiger Barb couples. The tank should be around 10-20 gallons in size, with plenty of hiding spots using plants, such as java moss, to provide shelter for the fry.

2. Ideal water parameters: To stimulate breeding, the water temperature should be slightly warmer than their typical range at 78-82°F (25-28°C). A pH of 6.5-7 is ideal, along with a GH of 8-12.

3. Condition the breeding pair: Feed the potential breeding pair high-quality live or frozen foods to get them in prime condition for spawning, such as brine shrimp, daphnia, and bloodworms.

4. Introduce the breeding pair: Select a healthy, active male and female Green Tiger Barb and place them together in the breeding tank. Monitor them closely, and once you observe courtship behavior, such as the male chasing the female, you can be certain that they are ready to breed.

5. Spawning: Green Tiger Barbs are egg scatterers, meaning they will release their eggs freely and the male will fertilize them. Be aware that the parents could eat the eggs, so either remove the adults after spawning or use a breeding trap to protect the eggs.

6. Raising the fry: Once the eggs hatch (typically within 2 days), start feeding the fry micro foods, such as infusoria or microworms. As they grow, transition to crushed high-quality flake food. Maintain water conditions and perform frequent water changes to ensure their health and growth.

By following these steps, you’ll be well-equipped to breed Green Tiger Barbs and grow your vibrant fish family.


Caring for Green Tiger Barbs can be an enjoyable and rewarding experience for beginners who follow the given guidelines. With proper tank setup, diet, and care, you can ensure the health and happiness of your fish. If you have any questions or suggestions, please feel free to leave a comment!
