About this fish
Longfin Betta is a labyrinth fish that breathes air from the surface. Males are beautiful but territorial and must be kept one to a tank; they prefer warm, still water.
Care tips
One male per tank — males fight, sometimes to the death.
Warm, stable water and gentle flow (strong currents stress them).
Carnivore: feed betta pellets plus frozen bloodworms/brine shrimp.
