Betta tussyae Care Guide - Habitat, Diet & Breeding

Betta tussyae is a small, richly coloured wild betta with a slender body and elegant, rounded fins. Depending on mood and condition, adults may show warm reddish, coppery or brown tones, often contrasted by darker edging and iridescent blue or green highlights on the fins and body. Males are typically the more intensely coloured sex.

This species is considerably less robust and less flamboyant than the common Siamese fighting fish, but it has a subtle beauty that appeals to aquarists interested in wild Bettas. Its colours deepen during courtship, territorial displays and other moments of excitement, when the fish may also spread its fins and display a stronger body pattern.

In nature, Betta tussyae lives among submerged leaves, roots, branches and dense marginal vegetation. The water is often very soft, acidic and heavily stained by tannins from decaying leaves and peat. These sheltered habitats provide numerous hiding places and keep the fish out of strong currents and bright, open water.

Like other labyrinth fish, it can breathe atmospheric air using its labyrinth organ, allowing it to survive in warm, poorly oxygenated swamp environments. It is a territorial but generally secretive species, spending much of its time moving carefully through cover rather than constantly patrolling open water.

Betta tussyae is native to the Malay Peninsula in Southeast Asia, particularly acidic peat-swamp and blackwater habitats of southern Peninsular Malaysia. It is associated with slow-moving, tannin-stained forest waters and small swamp streams.

A pair should have at least 40 litres, with a footprint of approximately 60 × 30 cm or larger; extra volume and floor space are valuable for a group. Use a tightly covered aquarium because Bettas can jump, while leaving a warm, humid air space above the water. Soft, acidic blackwater conditions, gentle filtration and subdued lighting suit this species. Add a dark sand or fine-gravel substrate, dried Indian almond or other aquarium-safe leaves, driftwood, roots, floating plants and dense vegetation to create secluded territories. Avoid strong currents and sharp decor, and provide easy access to the surface.

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

Betta tussyae is a carnivorous micropredator that naturally takes small aquatic invertebrates, insect larvae and tiny crustaceans. Offer a varied diet of high-quality small betta or carnivorous pellets supplemented with frozen or live foods such as daphnia, baby brine shrimp, mosquito larvae, cyclops and bloodworms. Small portions fed regularly are preferable to large meals, and uneaten food should not be allowed to accumulate.

Betta tussyae is best kept alone, as a compatible pair, or in a carefully planned small group with abundant cover. In a suitably spacious, peaceful blackwater aquarium it may live alongside small, non-aggressive fish such as chilli rasboras, small Boraras species, pencilfish and gentle dwarf corydoras. Avoid fin-nipping barbs, boisterous danios, larger gouramis, aggressive Bettas and other territorial fish. Males may quarrel, particularly in a small or sparsely furnished aquarium, so groups require space, visual barriers and a willingness to separate individuals.

Betta tussyae is a bubble-nesting species. Condition a compatible pair with plenty of small live or frozen foods, then provide broad leaves, floating plants or a small spawning shelter near the surface. The male generally constructs and maintains the nest, while the pair court beneath it and the eggs are placed among the bubbles. After spawning, the male guards the nest and tends the eggs until they hatch. Once the fry become free-swimming, remove the adults if necessary and feed the young infusoria or other microscopic foods before progressing to newly hatched brine shrimp.

Males are generally larger and more vividly coloured, with longer, fuller fins and stronger iridescent or reddish markings. Females usually have shorter fins, a rounder abdomen and more subdued coloration, although well-conditioned females can still display striking colours.
