Natural habitat

Betta gladiator is endemic to the Maliau Basin in Sabah, Malaysian Borneo, where it inhabits blackwater heath-forest streams. These streams are characterized by very soft water with a low pH, heavily stained with humic acids. The fish thrives in conditions that are often extreme for many freshwater species, as it prefers areas with dense vegetation where it can ambush prey and find shelter.

Where they are found

This species is endemic to the Maliau Basin and is found in very specific tropical freshwater habitats that are rich in organic materials.

Aquarium care

For optimal Betta care, it's essential to maintain a stable water temperature between 24°C to 27°C, use a gentle filter to avoid strong currents, and perform regular water changes of about 25% weekly to maintain water quality. Include live or silk plants to provide hiding spots and enrich the environment.

Feeding

This species is carnivorous, feeding primarily on small invertebrates in the wild, such as aquatic insects and crustaceans. In captivity, they thrive on live and frozen foods, including bloodworms and Daphnia. Fry should be introduced to foods such as microworms and Artemia nauplii shortly after they become free-swimming.

Compatibility

Bettas are territorial and generally aggressive, particularly males. They should not be housed together, as male Bettas will fight. Female Bettas can be kept in groups if the tank is large enough, but care should be taken to minimize stress during introductions.

Breeding

Breeding includes paternal mouthbrooding, where the male protects fertilized eggs in its mouth until they hatch. Breeding practices should mimic natural conditions as closely as possible.
