Coccina Betta

Coccina Betta (Betta coccina), often called the Wine Red Betta, is a small wild betta from the peat swamp forests of Sumatra and Peninsular Malaysia, first described by Jörg Vierke in 1979. Its body is a deep, iridescent wine red to dark red-brown, with blue-green highlights on the fins and striking blue eyes. Males are the more vivid of the pair, with longer fins and richer color. Females are slightly smaller, with shorter fins and a softer red-brown tone. In the right conditions, a pair of Coccina is one of the most beautiful and natural-looking wild betta displays you can keep.

In the wild, Coccina live in shaded, slow-moving swamp water stained the color of tea by fallen leaves, over a bottom of thick leaf litter. The water is extremely soft and acidic, with almost no current. Their habitat is being lost to deforestation and conversion to plantations, and the species is listed as Vulnerable on the IUCN Red List. That makes well-kept, breeding aquarium populations increasingly valuable.

Recreate those conditions and the fish will reward you. A 10-gallon or larger species tank works well, with dim lighting, a dark substrate covered in leaf litter, floating plants, and plenty of hiding places among wood and plants. Keep water movement to a minimum — a gentle sponge filter is ideal. Coccina are shy at first and will spend more time in the open, with better color, once they feel secure. Keep a tight-fitting lid: wild bettas jump, and a small gap is enough for an escape.

Coccina Bettas are bubble nesters. The male builds a small nest of bubbles at the surface, often tucked under a floating leaf or among plants. After spawning he places the eggs in the nest and guards them until the fry hatch and become free-swimming. Coccina are best kept as a bonded pair. In a larger, heavily planted tank they can also be kept as a small mixed group, where they will choose their own partners. Males become territorial while nesting, so give each pair room and plenty of cover. Spawns are small, and the fry need infusoria or micro-foods before moving on to baby brine shrimp.

Our wild bettas are kept in individual filtered, heated, and UV-sterilized homes — each fish with its own stable, carefully maintained water environment. Wild bettas are more sensitive to water quality than domesticated varieties and are maintained accordingly.

Wild bettas should be kept as species-only — they are not suitable community fish. Their water needs are far more specialized than those of typical community fish, and the shy Coccina is easily stressed or outcompeted at feeding time by more active tankmates. A dedicated species aquarium gives them the stable, quiet environment they require and lets their natural behavior be seen in full.
