Descrição da espécie
Geographical Origin and Habitat: A freshwater species; the enclosure should provide stability, oxygenation, space and shelter consistent with its behaviour without turning one habitat description into a mandatory recipe.
Taxonomy and Morphology: The accepted scientific name is Chromobotia macracanthus; the verified classification records genus Chromobotia, family Botiidae, subfamily Botiinae, order Cypriniformes. Historical names remain searchable as synonyms rather than separate species.
Social Behavior: Clown Loach is social and should be kept in a group. The minimum reference is 5 individuals; sex, maturity and available space can require a more conservative composition. Observe access to food, resting behaviour, chasing and use of shelter. Isolation, persistent competition or aggression means the number, composition or environment needs to be corrected.
Coloration and Sexual Dimorphism: Colour and shape can vary with age, sex, physiological state and environmental conditions. Identification and sexing require recognized species-level characters; one appearance or photograph is not enough.
Cuidado, criação e companheiros de tanque
Aquarium Setup: Clown Loach needs an aquarium of at least 800 litres, sized for adult body size and a minimum group of 5 individuals. Filtration, shelter and swimming room must match the species and the actual number kept. Volume alone does not make an enclosure suitable: tank shape and length, usable area, oxygenation and the ability to separate territories must reflect adult behaviour.
Diet and Feeding: The recorded diet is omnivorous. Offer appropriately sized foods varied within that category, and adjust quantity and frequency from actual intake, body condition and leftovers. One food or a fixed schedule is not suitable for every age and situation.
Water Quality: Maintain stable, well-oxygenated water appropriate to a freshwater species; the card's reference values are 25–30 °C, pH 6–7.5. Verify conditions with reliable tests and size maintenance and filtration to the actual load. Ranges are not automatic thresholds for treatment or rapid chemical correction.
Compatibility and Cohabitation: The cohabitation profile is a species to combine with caution, with a generally active temperament. Keep at least 5 individuals; tankmates, stocking density and decor must allow escape, rest and feeding without excessive competition. Watch interactions especially during feeding, maturity and breeding. Persistent chasing, injury or exclusion from food requires a change in stocking or layout, or separation of the animals.
Aquarium Breeding: The recorded reproductive profile is “oviparity”. Breeding should be attempted only with healthy adults, separation capacity and a plan for eggs or young. Do not treat unverified triggers, sex ratios or hatch times as universal for this species.
Risks and Diseases: Use a secure cover and close escape gaps. Prevent problems through quarantine of new arrivals, stable water, appropriate feeding and daily observation. Similar signs can have different causes, so check parameters, history and diagnosis before medication. Follow the product label and qualified aquatic-veterinary advice; there is no universal reduced dose for a species or family.

Perfil de peixe
- Temperamento
- Active
- Clown Loach has a generally active temperament. Insufficient space, an unsuitable social ratio or incompatible tankmates can substantially change observed behaviour.
- Dieta
- Omnivore
- They are omnivorous and require a varied diet to thrive and maintain their colors. Feed them high-quality sinking pellets, algae wafers, and fresh blanched zucchini. They also highly appreciate frozen bloodworms, brine shrimp, and live blackworms.
- Expectativa de vida
- 15-20 years
- Tamanho adulto
- 30 cm
- Proporção sexual
- Group
- Clown Loach is social and should be kept in a group. The reference minimum is 5 individuals and must not be read as permission to overcrowd the aquarium.
- Frequência de alimentação
- Twice daily
- Feed them small portions two to three times a day. Since they are primarily nocturnal, dropping food in just before lights out is highly recommended. Ensure the food reaches the bottom before faster top-dwelling fish consume it all.
- Carga biológica
- High
- Clown Loaches grow quite large and contribute a significant bioload to the aquarium. Exceptional biological and mechanical filtration is absolutely mandatory. Substantial, weekly water changes are critical to maintain the pristine water conditions they require.
- Fluxo
- Strong
- Originating from fast-flowing rivers in Indonesia, they love highly oxygenated, fast-moving water. Installing powerheads to create a strong current across the bottom will keep them active and healthy. Good surface agitation is essential to ensure maximum oxygen exchange.
- Risco de salto
- Yes
- While mostly benthic, they can jump if frightened or if water conditions deteriorate rapidly. A tight-fitting lid is essential, especially given their surprisingly fast swimming bursts. Ensure all filter cutouts are covered to prevent escape.
- Reprodução
- Oviparous
- Breeding the Clown Loach in a home aquarium is extraordinarily rare and difficult. They require massive tanks and specific hormonal triggers to spawn successfully. The majority of specimens in the hobby are either wild-caught or commercially bred with hormones.
- Compatibilidade e companheiros de tanque
- With caution
- The cohabitation profile is a species to combine with caution, with a generally active temperament. Keep at least 5 individuals; tankmates, stocking density and decor must allow escape, rest and feeding without excessive competition. Watch interactions especially during feeding, maturity and breeding. Persistent chasing, injury or exclusion from food requires a change in stocking or layout, or separation of the animals.
- Nível do tanque
- Bottom
- They are active bottom-dwellers that relentlessly comb the substrate for food. They require extremely large PVC pipes, driftwood, or smooth rock caves to sleep in. It is completely normal to find them resting on their sides, mimicking a dead fish.
