Male Betta

Betta pellets, frozen, live

Never with other male bettas or fin-nippers. Long fins are easy targets.

Bettas tolerate small tanks but thrive in 5gal+ with stable temperature and gentle filtration. They breathe air at the surface (labyrinth organ), so a tight lid with a small air gap is essential — bettas jump. Aquascape with silk or live plants (avoid sharp plastic), driftwood for hiding, and dim lighting. A sponge filter or a low-flow HOB keeps current minimal — bettas struggle in strong currents because of their fins. Almond leaves (Indian almond / catappa) tannin the water gently, mimicking their Southeast Asian habitat.

Solitary, surface-oriented, territorial. Builds bubble nests at the water surface when content. Recognises its keeper and learns feeding routines quickly. Flares gills + fins at perceived rivals — own reflection, neighbouring tanks, anything resembling another male betta. Hunts at the surface; dives to grab sinking food when motivated. Most active in the first few hours after lights-on.

Spawning is induction-style: condition a male and an unrelated female on live foods (brine, daphnia, blackworms) for 1–2 weeks, then introduce her to his tank with a divider. Once she displays vertical stripes and he builds a bubble nest, remove the divider. They embrace head-down at the surface, eggs drop, male catches them in his mouth and places each into the nest. Remove female immediately after spawning — he'll kill her if he can. Fry hatch in 24–48 hours; male tends nest for ~2 days then is removed. Feed fry infusoria, then microworms, then baby brine.

Most common issues: fin rot (water quality crashes — do 25% weekly changes, dose Indian almond leaves), velvet (yellow-gold dust on body — treat with copper or Methylene Blue), ich (white spots — raise temp to 86°F for 10 days), swim bladder (overfeeding — fast 2 days then peas). Bettas are sensitive to chlorine and chloramine; ALWAYS use a water conditioner.
