The Cochu's Blue Tetra (Boehlkea fredcochui) is also commonly called the Blue Tetra. It is one of the smaller tetras and is not as widely available in the U.S. as in some other parts of the world. They need to be kept in schools like other tetras with a 20 to 30 gallon being about the smallest fish tank size to start with.

Hint, they look great in heavily planted tanks!

The Cochu's Blue Tetra gets to be about 1.6 inches (4.1 cm) and they are generally considered easy to care for in the home aquarium. Like other tetras they can become fin nippers but keeping them in groups may help to limit the amount of fin nipping in your fish tank.

Origin / Habitat : South America, Amazon River basins.

Temperament / Behavior : May be fin nippers when not kept in appropriately sized aquariums and when not kept in large enough schools.
