Blue Sheatfish

Blue Sheatfish (Kryptopterus cryptopterus)
The Blue Sheatfish or Blue Glass Catfish is a captivating freshwater fish with a unique, transparent body and a faint blue hue.

They are slender and elongated, can measure between 6-8 inches in length depending on their genetics, diet, and living conditions.

These shy, peaceful fish are best kept in groups of at least 5 to help them feel secure. Ideal tank mates for the Blue Sheatfish would be larger peaceful fish that are not likely to harass or try to eat them. Since the Blue Sheatfish is a relatively shy and nocturnal species, it's important to choose tank mates that won't outcompete them for food or disturb their hiding spots during the day.
Some suitable tank mates include larger peaceful species like Congo Tetras, Bleeding Heart Tetra, Rasboras, peaceful Barbs, Pearl Gouramis, and Corydoras catfish. It's essential to research each species before adding them to the aquarium to ensure compatibility and provide a harmonious environment for all the fish.

Blue Sheatfish are omnivores, and their diet should include a mix of high-quality sinking pellets, freeze-dried bloodworms, brine shrimp, and daphnia. They may also eat some plant matter and algae, so supplementing with blanched vegetables can be beneficial.

The Blue Sheatfish is known to be nocturnal. These fish tend to be more active during the night and may hide during the day in their tank. Providing hiding spots, like caves, driftwood, or dense plants, can help create a comfortable environment for them to rest during the day. It's essential to consider this nocturnal behavior when planning their tank setup and observing their activity patterns.

The ideal tank habitat for Blue Sheatfish should replicate their natural environment, featuring soft, sandy substrate, hiding spots with driftwood, and rocks. Include live plants like Java Fern, Anubias, and Java Moss. Being active swimmers, they need open areas to race around. Lastly, adequate dim lighting and gentle water flow will make them feel more comfortable.

Considering their potential adult size of 6-8 inches and their need for swimming space, a minimum aquarium size of 60 gallons would be appropriate for the Blue Sheatfish. If you plan to keep a group of them or have other tank mates, a larger tank would be even better to ensure adequate space and a healthy environment for all the fish.

When it comes to water parameters, the Blue Sheatfish prefers a pH of 6.0-7.5, a hardness range of 5-15 dGH, and temperatures between 72-79°F (22-26°C).
