Orange Finned Loach (Yasuhikotakia modesta) – Complete Care Guide Description The Orange Finned Loach, also known as the Redtail Botia or Blue Botia, is a striking freshwater fish recognized for its metallic bluish-gray body contrasted by vivid orange to reddish fins. Native to Southeast Asian river systems, this species becomes more intensely colored as it matures. While visually appealing, it is an active and semi-aggressive loach best suited for experienced aquarists with larger aquariums. Water Parameters Clean, well-oxygenated water is essential: Temperature: 24–28°C (75–82°F) pH: 6.5–7.5 Hardness: 5–15 dGH Tank Size: Minimum 200–250 liters (50–65 gallons) Water Flow: Moderate to strong (river-like conditions) Water Changes: 25–30% weekly Care & Maintenance Orange Finned Loaches require space and proper tank conditions: Provide a large aquarium with open swimming areas. Use sand or smooth substrate to protect their barbels. Include rocks, driftwood, and caves for hiding and territory. Maintain excellent water quality—sensitive to poor conditions. Feed a varied omnivorous diet: sinking pellets, frozen foods (bloodworms, shrimp), and occasional vegetables. Ensure strong filtration and good oxygenation. Behaviour & Temperament Semi-aggressive and territorial, especially as adults. Active and energetic, exploring bottom and mid-levels. May chase or bully smaller or weaker fish. Can be kept singly or in groups (requires large tank to manage hierarchy). Juveniles are more peaceful; aggression increases with age. Compatibility Suitable for semi-aggressive community tanks. Best kept with robust, similarly sized fish. Avoid small or timid species. Suitable Tank Mates Larger barbs Rainbowfish Robust tetras Medium-sized cichlids (peaceful to semi-aggressive) Other loaches (in large tanks with caution) Tank Mates to Avoid Small fish (may be bullied or eaten) Slow-moving or delicate species Very aggressive fish that may cause conflicts Long-finned fish (may be nipped) Tiny bottom dwellers Pro Tips Provide strong water flow and oxygenation for best health. Use a tight-fitting lid—they can be active jumpers. Rearrange décor occasionally to reduce territorial disputes. Keep in larger tanks to manage aggression effectively. Feed regularly to minimize aggression caused by hunger. Monitor behavior and separate if necessary. Summary The Orange Finned Loach is a bold, active, and visually striking fish that thrives in larger aquariums. With proper space, strong filtration, and compatible tank mates, it becomes a dynamic and engaging addition to semi-aggressive setups.
