Blue sheatfish

Introduction

The Blue Sheatfish (Kryptopterus cryptopterus), also known as the Blue Glass Catfish, is a captivating freshwater species cherished by aquarists for its unique transparent body and subtle blue hue. This peaceful fish adds an elegant touch to community tanks and is suitable for hobbyists with some experience due to its specific care requirements.

Care and Environment

Providing optimal care for the Blue Sheatfish involves attention to tank size, water parameters, and environmental setup.

What is the minimum tank size for a Blue Sheatfish?

A minimum tank size of 150 liters (40 gallons) is recommended to accommodate a small group, as they thrive in the company of their own kind.

What are the ideal water parameters for Blue Sheatfish?

Maintain a pH between 6.3 and 6.9, water hardness of 8–16°N (142–285 ppm), and a temperature range of 22–26°C (71.6–78.8°F) to replicate their natural habitat.

How should the tank be set up for Blue Sheatfish?

Incorporate a soft, sandy substrate with ample hiding spots using driftwood and rocks. Include live plants like Java Fern, Anubias, and Java Moss to provide cover and mimic their natural environment. Ensure open swimming areas and use dim lighting to accommodate their nocturnal tendencies.

Filtration should be robust to maintain water quality, and a gentle water flow is preferred. Feed them a varied diet of high-quality sinking pellets, freeze-dried bloodworms, brine shrimp, and daphnia to meet their omnivorous dietary needs.

Origin and Habitat

Native to Southeast Asia, specifically Borneo and Indonesia, the Blue Sheatfish inhabits slow-moving rivers, streams, and floodplains with soft substrates and abundant vegetation. These environments are characterized by well-oxygenated, turbid waters with low to moderate currents.

Temperament and Compatibility

Blue Sheatfish are peaceful, schooling fish that should be kept in groups of at least five to ensure their well-being.

What are suitable tank mates for Blue Sheatfish?

Compatible companions include larger peaceful species such as Congo Tetras, Bleeding Heart Tetras, Rasboras, peaceful Barbs, Pearl Gouramis, and Corydoras catfish.

Are there any tank mates to avoid?

Avoid housing them with aggressive or overly boisterous species, as well as smaller fish that may be mistaken for food.

How can I create a harmonious tank environment?

Provide ample space and hiding spots to reduce stress and prevent territorial disputes, ensuring a peaceful community tank.

Interesting Facts

The Blue Sheatfish's transparent body allows observers to see its internal organs, making it a unique addition to aquariums. In the wild, they are known to be nocturnal, becoming more active during the night. Despite their popularity among aquarists, successful breeding in home aquariums has not been documented, adding an element of rarity to their care.
