The Royal Clown Loach, scientifically known as Leptobotia elongata, is a species of freshwater fish native to East Asia, particularly China and Vietnam. These loaches are characterized by their elongated body shape and striking coloration, featuring a combination of dark brown and yellow-orange stripes or spots along their body.

They are bottom-dwelling fish that inhabit rivers and streams with moderate to fast-flowing water. In aquariums, they prefer spacious tanks with plenty of hiding places like rocks, driftwood, and plants. Royal Clown Loaches are peaceful and sociable fish, often found in groups in the wild and should ideally be kept in small groups in captivity.

These loaches are omnivorous and will accept a variety of foods including sinking pellets, frozen or live foods, and algae wafers. Due to their scavenging nature, they help in keeping the aquarium substrate clean by consuming leftover food and detritus. However, they may occasionally uproot plants, so sturdy plants or artificial decorations are recommended.

Overall, the Royal Clown Loach is a fascinating and attractive species suitable for community aquariums with appropriate tank mates and care.
