Cochus Blue Tetra (Boehlkea fredcochui) Fish Species Profile

Cochu's Tetras are generally peaceful and gentle fish and extremely active, are not demanding and relatively simple to look after. However, they may occasionally nip on the fins of other larger and slow-moving fish if there is not enough swimming space for them.

The Cochu's Blue Tetra is an excellent choice for medium to large-sized community aquariums, especially well-planted aquariums. It is recommended to keep this species of Tetra in groups of at least six as this shoaling fish does better when part of a group. It would be better if you didn't keep these Tetras with other fish that are aggressive; otherwise, those fish will outcompete them for food.

The Cochu's Blue Tetra has a silvery blue streamlined body that varies from sky blue to dark shiny blue and displays a blueish horizontal stripe at the lateral line with a dark spot at the caudal fin. They have a curved tail and translucent fins. Sometimes you will also find pink colouration at the base of the tail.

Origins of the Cochus Blue Tetra

Cochu's Blue Tetras are native to Rio Maranon, in Peru in the Amazon Basin In South America. They inhabit streams and rivers that are rich in tannins and leaf litter with a varied range of water temperatures and water acidity which enable these fish to survive in the harshest of environments.

Diet

Cochu's Blue Tetras are not picky eaters and will thrive and remain very colourful on a varied diet of high-quality flake food granules, micro pellets, and frozen, live or freeze-dried foods. Foods such as tubifex, mosquito larvae, brine shrimp and bloodworms will all be readily accepted.

Sexing the Cochus Blue Tetra

It is relatively straightforward to differentiate males from females by their slimmer, more streamlined body and are usually more intensely coloured. In contrast, the females are more expansive, less streamlined, and are generally duller in colour than the male.

Breeding the Cochus Blue Tetra

The Cochu's Tetra is an egg scatterer and is relatively easy to breed. These Tetras require a dimly lit tank with some fine leaved plants and

soft, acidic water if the eggs are to hatch.

Well-conditioned females will deposit their eggs on the bottoms of broadleaf plants.

Because the parents consume the eggs, successful breeders will remove the eggs and place them in a grow-out tank immediately after spawning is completed.

Once hatched the fry can be fed finely crushed flake food, infusoria or newly hatched brine shrimp.
