Dicas de identificação
Coloration and Banding
The most distinctive feature is the bright orange/red body with three prominent, black, wedge-shaped vertical bands. No other loach species shares this exact pattern.
Barbels
Presence of four pairs of barbels around the mouth, which are sensory organs used for foraging in the substrate.
Suborbital Spine
A sharp, retractable spine located beneath each eye. This spine can be extended when the fish feels threatened and can get entangled in nets or cause injury during handling.
Body Shape
Elongated and somewhat compressed body, typical of many loach species, but combined with the unique coloration, it's unmistakable.
Habitat
- Tipo de água
- freshwater
- Profundidade
- Typically found in shallow to moderately deep waters of rivers and floodplains.
- Ambiente
- Native to slow-moving to moderately flowing rivers, tributaries, and floodplains. They prefer areas with soft substrates (sand or mud), abundant submerged vegetation, roots, and driftwood, which provide shelter and foraging opportunities. During the rainy season, they migrate into flooded forests and plains.
- Distribuição geográfica
- Native to the islands of Sumatra and Borneo in Southeast Asia (Indonesia and Malaysia).

- Requisitos especiais: Requires a well-established aquarium with excellent filtration and good water flow. Provide plenty of hiding places such as caves, driftwood, and dense planting. A soft substrate (sand or fine gravel) is essential as they like to dig. They are sensitive to poor water quality and sudden changes in parameters. Prone to Ich (white spot disease) if stressed or in unstable conditions.

Fatos principais
Nocturnal Foragersbehavior
While active during the day, Clown Loaches are primarily nocturnal foragers, using their sensitive barbels to locate food in the substrate.
Sound Productioninteresting
Clown Loaches are known to produce audible clicking sounds, especially during feeding or when excited. This sound is believed to be produced by grinding their pharyngeal teeth.
Sleeping Behaviorbehavior
They often rest in unusual positions, such as lying on their sides or upside down, which can alarm inexperienced aquarists who might mistake them for being dead.
Longevityrecord
With proper care, Clown Loaches can live for a remarkably long time, often exceeding 15-20 years in captivity, with some reports of individuals living over 25 years.
Snail Eatersbehavior
They are highly effective at controlling snail populations in aquariums, making them a popular choice for tanks with nuisance snails.
Informações de segurança
Manusear com cuidado- Nível de segurança: caution
- Venenoso: Não
- Comestibilidade: not recommended
- Observações de manuseio: When handling Chromobotia macracanthus, extreme caution should be exercised due to the presence of sharp, retractable suborbital spines located beneath each eye. These spines can become entangled in nets, causing injury to the fish, or can puncture skin if handled carelessly. It is advisable to use a solid container or a fine-mesh net to transfer them, avoiding direct contact with the spines. They are not venomous, but the puncture wounds can be painful and prone to secondary infection.
