Apri l'appDescrizione
The Clown Loach, Chromobotia macracanthus, is a freshwater fish belonging to the family Botiidae. It is highly prized in the aquarium trade for its striking coloration, active behavior, and social nature. This species is characterized by its elongated, somewhat compressed body, vibrant orange to reddish-orange base color, and three broad, black, wedge-shaped vertical bands. They are bottom-dwelling fish, often found in schools, and are known for their playful antics and ability to hide in crevices. They possess a pair of sharp, erectile spines located beneath each eye, which are typically used for defense.

Consigli per l'identificazione
Coloration and Banding
The most distinguishing feature is the bright orange to reddish-orange body with three prominent, black, wedge-shaped vertical bands. No other loach species shares this exact pattern.
Suborbital Spine
Observe for the presence of a sharp, erectile spine located beneath each eye. This spine is a key characteristic of the Botiidae family and can be seen when the fish is stressed or handled.
Barbels
Count the four pairs of barbels around the mouth, which are used for foraging in the substrate.
Body Shape
Note the elongated, somewhat compressed body shape, typical of many loach species, but combined with the unique color pattern.
Habitat
- Tipo di acqua
- freshwater
- Profondità
- Typically found in shallow to moderate depths, often near the bottom.
- Ambiente
- Native to clear, flowing rivers and tributaries, as well as floodplains during the rainy season. They prefer areas with plenty of submerged vegetation, roots, and rocky crevices for shelter. The substrate is usually sand or fine gravel.
- Areale geografico
- Native to the islands of Sumatra and Borneo in Southeast Asia, specifically in the river systems of Indonesia (Sumatra, Kalimantan) and Malaysia (Sarawak).
Informazioni sull'acquario
- Livello di cura: intermediate
- Temperamento: semi-aggressive
- Dieta: omnivore
- Dimensione minima della vasca: 75 gallons (280 liters) for a small group, larger for adults
- Temperatura: 75-86°F (24-30°C)
- Livello di pH: 6.0-7.5
- Durezza: 5-12 dGH
- Compatibilità: Generally peaceful with similarly sized, non-aggressive fish. Best kept in groups of 5 or more to reduce stress and encourage natural behavior. Avoid keeping with very small or slow-moving fish that might be intimidated or outcompeted for food. Can be territorial towards other bottom-dwellers if not given enough space or if kept in insufficient numbers.
- Requisiti speciali: Requires a well-established aquarium with excellent filtration and regular water changes. Provide plenty of hiding places such as caves, driftwood, and dense planting. A soft substrate (sand or fine gravel) is preferred as they like to dig. Dim lighting is appreciated. They are sensitive to poor water quality and medications, especially those containing copper. Due to their potential large size and schooling nature, a spacious tank is crucial.
Informazioni in natura

- Importanza commerciale: high
- Sapore: Not commonly consumed due to their value as ornamental fish and relatively small size for food.

Fatti chiave
Nocturnal Activitybehavior
While often active during the day in aquariums, Clown Loaches are naturally more crepuscular and nocturnal, becoming most active during dawn, dusk, and nighttime.
Sound Productioninteresting
Clown Loaches are known to produce audible clicking sounds, especially during feeding or when excited. This sound is believed to be generated by grinding their pharyngeal teeth.
Growth Raterecord
These fish are slow growers but can reach impressive sizes of up to 12-16 inches (30-40 cm) in optimal conditions, making them one of the largest loach species commonly kept in aquariums.
Sleeping Habitsbehavior
Clown Loaches often 'play dead' by lying on their sides or even upside down, especially when resting or stressed. This behavior can be alarming to new aquarists but is generally normal for the species.
Taxonomic Reclassificationevolution
Originally classified under the genus Botia, Chromobotia macracanthus was reclassified into its own monotypic genus, Chromobotia, in 2004 due to distinct morphological and genetic differences.
Informazioni di sicurezza
Maneggiare con cura- Livello di sicurezza: caution
- Velenoso: No
- Commestibilità: not recommended
- Note sul maneggio: When handling Clown Loaches, extreme caution should be exercised due to the sharp, erectile suborbital spines. These spines can easily snag nets or puncture skin, causing a painful wound. It is best to guide them into a container rather than netting them directly. If netting is necessary, use a fine-mesh net and be very gentle to avoid entanglement or injury to the fish or handler.
