Angelicus Botia Loach

Angelicus Botia Loach

The Angelicus Botia Loach (*Botia hymenophysa*), also known as the Angelicus Loach, is a fascinating freshwater fish native to the streams and rivers of Southeast Asia, particularly in Laos and Thailand. Renowned for its striking appearance and playful behaviour, this loach is a popular choice among aquarists seeking to add personality and interest to their aquariums.

Physical Characteristics:

• Size: Angelicus Botia Loaches can grow to about 15-20 cm (6-8 inches) in length.
• Coloration:
  • Body: They exhibit a light brown to golden base colour with distinctive dark brown to black bands or spots running along their body.
  • Fins: Their fins are usually translucent with hints of the body colour, which adds to their overall attractiveness.
• Shape: Angelicus Loaches have a robust and elongated body, which is typical of many loach species, allowing them to navigate through various substrate types in their natural habitat.

Behaviour:

• Temperament: Angelicus Botia Loaches are generally peaceful fish that thrive in community tanks. However, they can exhibit territorial behaviour, especially as they mature.
• Activity Level: These loaches are active swimmers and are often seen exploring their environment, foraging for food, and interacting with tankmates.
• Community Behaviour: They do well in groups of three or more, as they are social creatures and enjoy the company of their own kind.

Aquarium Care:

• Tank Size: A minimum tank size of 100 litres (26 gallons) is recommended for a small group of Angelicus Botia Loaches to provide ample swimming space.
• Water Parameters:
  • Temperature: They prefer warmer waters, with an ideal temperature range of 24°C to 28°C (75°F to 82°F).
  • pH: A slightly acidic to neutral pH range of 6.0 to 7.5 is best for their health.
  • Hardness: Soft to moderately hard water, with a general hardness (GH) of 5-15 dGH, is ideal.
• Tank Setup:
  • Substrate and Decorations: A soft, sandy substrate is recommended to protect their sensitive barbels. Provide hiding spots using caves, driftwood, and live or artificial plants to create a comfortable environment.
  • Lighting: Moderate lighting is suitable, and using floating plants can provide shaded areas.
  • Filtration: A gentle filtration system is essential, as strong currents can stress these loaches. Regular water changes (about 20% weekly) are necessary to maintain optimal water quality.

Diet:

Angelicus Botia Loaches are omnivorous and require a varied diet to thrive:

• Pellets: High-quality sinking pellets formulated for bottom-dwelling fish should form the staple of their diet.
• Live or Frozen Foods: Offer live or frozen foods such as bloodworms, brine shrimp, and daphnia to provide essential protein and variety.
• Vegetable Matter: Occasional feedings of blanched vegetables like zucchini or spinach can be beneficial for their health.

Breeding:

Breeding Angelicus Botia Loaches in captivity is challenging, and successful breeding is rare. However, if attempted:

• Breeding Setup: A separate breeding tank with gentle filtration and ample hiding spots is ideal. The water should be kept slightly cooler (around 22°C to 24°C or 72°F to 75°F).
• Spawning Behaviour: These fish are egg layers, and spawning typically occurs in the early morning. The female may lay hundreds of eggs on the tank surfaces, which the male fertilises.
• Fry Care: Once the fry hatch, they can be fed infusoria or powdered fry food until they are large enough to eat finely crushed pellets.

Special Considerations:

• Social Structure: Providing them with tankmates is beneficial for their well-being, but avoid housing them with overly aggressive species.
• Water Quality: Regular water testing and changes are crucial to prevent stress and illness.
