Bettas are labyrinth fish from the slow, warm waters of Southeast Asia, able to gulp air from the surface.
Centuries of selective breeding produced the long finnage and bright colours sold today, but the fish beneath is hardy and learns to recognise its keeper.
Despite their reputation as desk ornaments, bettas do well only in a heated, filtered, cycled tank.
Their tolerance of poor water is a survival trait, not a reason to skip proper care.
Given a stable setup they are interactive and long-lived.
Housing
Provide at least 19 litres (5 gallons) with a gentle filter and a reliable heater holding 25-28C (78-82F).
A tight lid is essential, as bettas jump and need an undisturbed warm air layer to breathe.
Silk or live plants and a cave give security and resting spots near the surface.
Keep flow low, since long fins tire in strong currents.
Cycle the tank before adding the fish and aim for ammonia and nitrite at zero and nitrate under 20ppm.
Bowls, vases, and unheated nano cubes are inadequate and shorten lifespan.
Diet
Bettas are carnivores and need a meat-based diet.
Feed a quality betta-specific pellet as the staple, supplemented several times weekly with frozen or live bloodworms, daphnia, and brine shrimp.
Variety supports colour, finnage, and digestion.
Feed only what is eaten in two minutes, once or twice daily, and include a weekly fasting day to reduce constipation and bloating.
Overfeeding is a leading cause of swim-bladder problems and fouled water in betta tanks.
Health
Common ailments are fin rot, fungal infections, and swim-bladder disorder, most traceable to cold water, poor filtration, or overfeeding.
Stable warmth and clean parameters prevent most disease.
Watch for clamped fins, lethargy, and loss of appetite as early warning signs.
Long-finned and double-tail forms can suffer fin-weighting and spinal issues.
Quarantine new plants and decor, avoid sharp ornaments that tear fins, and treat illness promptly with the correct medication rather than salt alone.
Temperament
Males are territorial and must be housed alone, as two males will fight and even a mirror can stress them.
The name Siamese fighting fish reflects this instinct.
They do not need company and are content as the sole occupant.
They become curious and bold once settled, flaring, following fingers, and learning feeding routines.
Females can sometimes share a heavily planted larger tank as a sorority, but this is advanced and not recommended for beginners.
