Clown Loach: A Guide to Care and Keeping Clown loaches (Chromobotia macracanthus) are popular freshwater fish known for their vibrant colors and playful behavior. They are native to Indonesia, specifically the islands of Borneo and Sumatra. Here’s a guide to understanding and caring for these fascinating fish: 1. Characteristics & Behavior: Appearance: Bright orange body with three distinct black vertical bands, and red fins. Size: Can grow up to 12 inches (30 cm) in length. Lifespan: Can live for 10-20 years or more with proper care. Social: Highly social, thrive in groups of at least 5-6 (preferably more). Active & Playful: Known for their active swimming, exploring, and engaging in playful behavior with tank mates. Nocturnal: More active during the night and may be less active during the day, often hiding in caves or plants. 2. Aquarium Requirements: Tank Size: Large tanks are necessary, with a minimum of 75 gallons (284 liters) for a group of 5-6. Water Parameters: Temperature: 77°F-86°F (25°C-30°C). pH: 6.0-7.5 (slightly acidic to neutral). Hardness: Moderate. Filtration: Excellent water quality and strong water movement are crucial; consider a powerful filter like a canister filter. Substrate: Soft, smooth substrates like sand or fine gravel to protect their barbels. Hiding Places: Provide ample hiding spots with plants, driftwood, and rocks. 3.

Tank Mate Considerations: Avoid housing them with aggressive fish, those with long fins, very small fish, or invertebrates, unless the invertebrates are intended as food. Compatible Species: Examples of good tank mates include Discus, Rainbowfish, Barbs, Tetras, Severums, Plecos, and Kuhli Loaches. 5. Common Health Issues: Susceptibility to Ich: Clown loaches are prone to Ich, a parasitic infection, especially when stressed.
