The Tiger Barb (Puntigrus tetrazona), known for its distinctive black vertical stripes and active behavior, is a popular freshwater fish in the aquarium hobby. Here's some information about their care and lifestyle:

1. Appearance:

   • Tiger Barbs have a silver or gold body with four prominent black vertical stripes.
   • The fins may be red or orange, and the intensity of the coloration can vary.

2. Size:

   • They typically grow to about 2 to 3 inches (5 to 7.5 cm) in length, depending on the specific conditions and care provided.

3. Habitat and Tank Setup:

   • Native to Southeast Asia, Tiger Barbs are found in clear, flowing waters.
   • Provide a well-aerated aquarium with a strong filtration system. Tiger Barbs appreciate moderate water flow.
   • Decorate the tank with plants, rocks, and driftwood, but leave open swimming spaces.
   • Maintain a temperature range of 74°F to 79°F (23°C to 26°C) and a pH between 6.0 and 7.5.

4. Diet:

   • Tiger Barbs are omnivores and will accept a variety of foods.
   • Offer a balanced diet of high-quality flakes, pellets, and supplemented with live or frozen foods like brine shrimp, bloodworms, or daphnia.

5. Behavior:

   • Tiger Barbs are known for their active and sometimes fin-nipping behavior.
   • They are schooling fish and should be kept in groups of at least six individuals to disperse aggression and establish a hierarchy.
   • Mixing them with other aggressive fish or species with long fins should be done cautiously.

6. Tank Mates:

   • Choose tank mates carefully. Avoid slow-moving or long-finned species, as Tiger Barbs may harass them.
   • Suitable tank mates include other active and robust community fish.

7. Breeding:

   • Tiger Barbs are egg scatterers. Breeding can occur in the home aquarium if provided with suitable conditions.
   • Use fine-leaved plants or spawning mops for egg-laying sites.
   • If breeding is not a goal, separate adults from the eggs or fry, as they may consume them.

8. Maintenance:

   • Regular water changes and proper filtration are important to maintain water quality.
   • Monitor for signs of aggression and ensure that the aquarium environment remains suitable for all inhabitants.

While Tiger Barbs are generally hardy and adaptable, their active nature and sometimes nippy behavior mean that tank mates should be chosen carefully. Providing a well-structured environment and keeping them in a suitable group size can help prevent aggressive behavior within the school.
