The Imperial Flower Loach (Leptobotia elongata or often Botia rostrata, depending on regional naming) is a striking and energetic freshwater fish admired for its bold colors, unique flower-like patterns, and active personality. Reaching 8–10cm, it’s a mid-sized loach species that thrives in cool, fast-flowing aquariums with plenty of room to swim, smooth substrates, and natural decor like rocks and driftwood.

This loach originates from river systems in China and surrounding regions, where it lives in oxygen-rich, flowing waters. Its curious, social nature and vibrant patterning make it a great addition to aquariums with other peaceful riverine species.

🐠 Key Features:

• Scientific Name: Leptobotia elongata (or related Botia species, depending on source)

• Temperament: Peaceful, energetic, slightly territorial when crowded

• Tank Zone: Bottom to mid-level

• Difficulty Level: Intermediate

• Best kept in groups of 3 or more in well-oxygenated tanks

🌊 Water Conditions

This species requires clean, oxygen-rich, and slightly cool water, with moderate to strong flow to mimic its riverine origins.

• Temperature: 20–25°C (68–77°F)

• pH: 6.5–7.5

• Hardness: 5–12 dGH

• Tank Size: Minimum 40 gallons (bigger for groups)

• Substrate: Fine gravel or sand (smooth)

• Filtration: Strong with good current and aeration

• Lighting: Moderate

• Decor: River rocks, driftwood, caves, and smooth surfaces

These loaches are strong swimmers, so provide open areas for activity along with plenty of hides to retreat.

🐟 Tank Mates

Imperial Flower Loaches are peaceful but active. They do well in community tanks with similarly sized, fast-moving or peaceful species.

Good companions:

• Rosy barbs

• Hillstream loaches

• White Cloud Mountain minnows

• Danios (e.g., Zebra or Kyathit)

• Rainbowfish

Avoid:

• Aggressive or overly large fish

• Slow-moving or delicate species

• Tiny shrimp (may be seen as food)

Group housing reduces aggression and brings out natural, playful behavior.

🍽️ Feeding Habits

Imperial Flower Loaches are omnivores and bottom feeders, constantly grazing on surfaces and digging through substrate for food.

Recommended diet:

• Sinking pellets and bottom wafers

• Frozen and live foods (bloodworms, brine shrimp, blackworms)

• Blanched veggies (zucchini, spinach, cucumber)

• Occasional algae wafers and spirulina-based feeds

Feed once or twice a day, and always make sure food reaches the bottom of the tank.

🧼 Care Tips:

• Maintain excellent water quality—perform 25–30% water changes weekly

• Keep the tank securely covered (loaches can jump)

• Avoid sharp decor that may damage their soft undersides or barbels

• Provide good water flow using powerheads or directional outputs

• Watch for signs of stress or hiding—these loaches need groups and hiding places to feel safe
