Longfin Blue Danio

The Longfin Blue Danio has an iridescent light blue body with long, flowing fins. This aquacultured variant is not available often.

Many tropical community aquariums are populated with tetras, rasboras and other similar schooling fish. Though these fish are rather small, their pleasant temperaments, the schooling behaviors they exhibit and a vast variety of colors and shapes make them popular in the hobby. They can grow anywhere from a few centimeters to a few inches and can add movement to a freshwater fish tank. Most of these fish are fairly easy to care for and have similar water chemistry and care requirements.

Tetras are probably the largest group of fish offered for community aquariums. They can be distinguished from other schooling community fish by the small adipose fin present between the dorsal fin and the tail. Tetras include small species such as the vibrant neon and cardinal tetras to much larger and more robust species like Buenos Aires Tetras and Congo Tetras.

Danios are commonly recommended as “starter fish” and dither fish. They are fast and active swimmers and they like a long tank to swim in. Danios have interesting markings and are generally hardy and peaceful.
