Betta livida Care Guide - Habitat, Diet & Breeding

Betta livida is a small wild betta with a dark, understated appearance that becomes much more striking under aquarium lighting. Mature males may show blue-green iridescence across the body and fins, often contrasting with reddish or dusky fin tones. Its compact form and relatively short fins distinguish it from many selectively bred ornamental bettas.

Betta livida is native to the peat-swamp forests and blackwater habitats of Selangor in Peninsular Malaysia, including areas around Kuala Lumpur. It comes from Southeast Asia and is associated with shallow, heavily shaded waters rich in leaf litter and dissolved tannins.

Provide at least 40 litres for a single adult or pair, with a footprint around 60 × 30 cm or larger preferred over a tall aquarium. Use soft, acidic, tannin-rich water, gentle filtration, subdued lighting, and a secure cover because bettas can jump and regularly breathe atmospheric air. A dark sand or fine-leaf substrate, driftwood, dried leaves, floating plants, dense marginal cover, and open areas between the furnishings recreate the sheltered peat-swamp environment.

Males reach about 5 cm (2 in) in total length, while females are usually smaller at approximately 4–4.5 cm (1.6–1.8 in).

This species is a carnivore that naturally feeds on small aquatic insects, insect larvae, crustaceans, and other tiny invertebrates. Offer a varied diet of appropriately sized frozen or live foods such as bloodworm, daphnia, mosquito larvae, brine shrimp, and blackworm. High-quality micropellets can be useful, but should complement rather than replace meaty foods.

Betta livida is best kept alone, as a compatible pair, or in a carefully planned species aquarium. It may coexist with peaceful, small blackwater fish such as certain small rasboras, pencilfish, or gentle kuhli loaches when the aquarium is spacious and densely furnished. Avoid fin-nipping species, boisterous tankmates, other territorial bettas, and similarly shaped gouramis; males may also fight with one another.

Betta livida is a bubble-nesting species that can be bred as a compatible pair in a mature, quiet aquarium. The male constructs a nest beneath floating leaves or other cover, courts the female, and gathers the eggs into the nest after spawning. He guards the eggs and newly hatched fry until they become free-swimming, after which the young can be raised on infusoria or another suitably tiny first food before moving on to baby brine shrimp.

Males are generally larger and display stronger blue-green iridescence, darker coloration, and more developed fins. Females are shorter-bodied and less vividly coloured, and a mature female may show a visible ovipositor or pale egg spot behind the pelvic fins.
