🌿 Recommended Aquarium Setup

• Minimum Tank Size: 10–15 liters (single betta)

• Ideal Tank Size: 20 liters or larger

• Moderate lighting

• Live plants such as:

  • Anubias

  • Java fern

  • Bucephalandra

  • Java moss

• Floating plants for shaded resting areas

A calm, planted environment helps this fish display its full beauty.

🐟 Tank Mates Compatibility

Best kept as a single centerpiece fish, but possible tank mates include:

• Corydoras catfish

• Small rasboras

• Nerite snails

• Amano shrimp (in larger tanks)

Avoid:

• Other male bettas

• Fin-nipping fish

• Aggressive species

• Fast, hyperactive fish

Long-fin bettas are vulnerable to fin damage in busy community tanks.

🍽 Feeding Habit

• Carnivorous diet

Supplement with:

• Frozen bloodworms

• Brine shrimp

• Daphnia

• Mosquito larvae

Feeding guidelines:

• Feed 1–2 small meals daily

A varied protein diet enhances color and fin growth.

• Monitor fins for signs of tearing or rot

• Provide occasional flaring exercise using mirror or reflection
