The Ghost Glass Catfish, known scientifically as Kryptopterus bicirrhis, is a mesmerizing species that captivates aquarists with its nearly transparent body and peaceful nature. Originating from the calm, clear waters of Southeast Asia, this ethereal fish provides a unique visual experience, allowing observers to see right through to its bones and internal organs. Its delicate appearance and intriguing behavior make it a fascinating addition to any peaceful freshwater aquarium.

Overview and Appearance:
- Scientific Name: Kryptopterus bicirrhis
- Family: Siluridae
- Size: Up to 4-6 inches (10-15 cm)
- Lifespan: 5-8 years in optimal conditions

The most striking feature of the Ghost Glass Catfish is its transparent body, which provides natural camouflage in the wild. They have a slender, elongated body with a forked tail and two long barbels near their mouth. Despite their fragile appearance, they are quite hardy when kept in proper conditions.

Habitat and Tank Requirements:
Creating a comfortable environment for Ghost Glass Catfish involves simulating their natural habitat:
- Water Parameters: Slightly acidic to neutral pH (6.5-7.0), with a temperature range of 75-80°F (24-27°C).
- Tank Setup: A minimum tank size of 20 gallons for a small group. The aquarium should be well-planted with dim lighting to mimic their natural, shaded environment. Provide plenty of hiding spots with caves, driftwood, and plants.
- Filtration: Gentle to moderate filtration is preferred to avoid strong currents, as they inhabit calm waters in the wild.

Diet and Nutrition:
Ghost Glass Catfish are carnivorous and require a diet rich in protein:
- High-quality, small-sized pellets or flakes as a staple.
- Regular feedings of live or frozen foods such as brine shrimp, bloodworms, or daphnia to maintain optimal health and encourage natural foraging behavior.
- Ensure food particles are small enough for them to ingest comfortably.

Behavior and Compatibility:
Ghost Glass Catfish are known for their peaceful and schooling nature:
- Best kept in groups of 5 or more to provide security and encourage natural behavior.
- Suitable for community tanks with other peaceful, small-to-medium-sized fish.
- Avoid housing with large, aggressive fish that may stress or prey upon them.

Breeding:
Breeding Ghost Glass Catfish in captivity is quite rare and challenging:
- Requires precise water conditions, including a slight drop in temperature and increased water changes to mimic the onset of the rainy season in their natural habitat.
- If breeding occurs, the fry are delicate and require infusoria or other micro-foods initially.

The Ghost Glass Catfish is a unique and intriguing addition to the freshwater aquarium, offering a glimpse into the less visible aspects of aquatic life through its transparent form. Their calm demeanor and schooling nature make them a peaceful and fascinating addition to a community tank. With the right tank setup, a diet rich in protein, and a gentle, well-structured environment, these ethereal beauties can thrive, bringing a touch of mystery and elegance to the underwater world of the home aquarium. As with all fish, understanding and catering to their specific needs ensures a healthy, vibrant life for these captivating creatures.
