Betta splendens: A Comprehensive Guide to the Splendid Siamese Fighting Fish

Introduction

Betta splendens, commonly known as the Siamese fighting fish, is an iconic aquarium species renowned for its vibrant colors and aggressive behavior. Their captivating appearance and intriguing social interactions make them popular among aquarists and enthusiasts alike.

Classification and Distribution

Betta splendens belongs to the family Osphronemidae, comprising labyrinth fishes characterized by their ability to breathe atmospheric oxygen through a modified organ called the labyrinth. It originated from the Mekong River Basin in Southeast Asia, primarily in Thailand, Cambodia, Laos, and Vietnam.

Physical Characteristics

These fish are characterized by their elongated, laterally compressed bodies and flowing fins, particularly the males' elaborate caudal and anal fins. Male bettas can grow up to 3 inches in length, while females tend to be slightly smaller. Their scales shimmer with iridescent colors ranging from blue, green, and red to metallic gold and turquoise.

Biology and Behavior

Aggression and Territoriality

Betta splendens is well-known for its aggressive nature, especially among males. They are territorial and will defend their space fiercely from perceived threats, displaying aggressive behaviors such as flaring, biting, and chasing.

Courtship and Breeding

Male bettas engage in elaborate courtship rituals when they encounter receptive females. They flare their fins, dance, and build bubble nests at the water's surface. After spawning, the male typically cares for the eggs and young in the bubble nest.

Lifespan and Care

In well-maintained aquariums, Betta splendens can live for up to 5 years. They prefer warm waters (78-86°F) with a neutral pH (6.5-7.5) and moderate hardness. A 5-gallon tank is recommended for a single betta, and a larger tank is required for multiple individuals or breeding purposes.

Aquarium Setup and Maintenance

Habitat

Betta splendens requires a well-planted aquarium with plenty of hiding places. Live plants provide both shelter and environmental enrichment. Floating plants, such as duckweed, can help diffuse light and reduce stress levels.

Filtration and Lighting

A gentle filter is essential to maintain water quality. Bettas prefer subdued lighting, so dim or indirect lighting is suitable.

Water Parameters

Regular water changes are crucial to maintain optimal water parameters. The following parameters are recommended:
- Temperature: 78-86°F (26-30°C)
- pH: 6.5-7.5
- Hardness: 5-15 dGH

Nutrition and Feeding

Betta splendens are primarily carnivorous and thrive on a diet of live or frozen foods such as brine shrimp, bloodworms, and daphnia. They can also be fed high-quality commercial betta pellets. Feed your betta once or twice a day, offering only what they can consume within a few minutes.

Health and Disease

Common health problems in Betta splendens include:

• Fin rot: Bacterial infection leading to deterioration of fins
• Velvet: Parasitic infection with a "gold dust" appearance
• Dropsy: Bacterial or viral infection causing swelling and fluid accumulation
• Ich: Parasitic infection with white, seed-like spots

Color Variations and Genetics
