Cochus Blue Tetra - Boehlkea fredcochui : Complete Fish Profile & Care Guide
Table of contents
IntroductionCochu' s Blue Tetras (Boehlkea fredcochui) are truly remarkable and vibrant fish that will add a pop of color to any aquarium. These gentle and active creatures are relatively low-maintenance, making them perfect for novice aquarists. However, it is worth noting that these tetras may nip on the fins of larger, slower-moving fish if there isn' t enough space for them to swim. If you' re looking for an ideal community aquarium fish, the Cochu' s Blue Tetra is an excellent choice for medium to large-sized tanks, especially those with plenty of plants. It is highly recommended to keep them in groups of six or more as they thrive in shoals. Be mindful of keeping them with aggressive fish, as these Tetras may struggle to compete for food. In terms of appearance, the Cochu' s Blue Tetra boasts a stunning silvery blue streamlined body that ranges from sky blue to dark, shiny blue. A blueish horizontal stripe at the lateral line, coupled with a dark spot at the caudal fin, adds to their beauty. They also have a curved tail and translucent fins, and sometimes, you may spot pink coloration at the base of their tail.

Natural HabitatThe Cochu' s Blue Tetra originates from the stunning River Marañón, situated in the heart of Peru' s Amazon Basin. These tetras thrive in an array of aquatic conditions, ranging from varying water temperatures to acidity levels, allowing them to flourish even in the harshest of environments. In their natural habitat, Cochu' s Blue Tetras prefer streams and rivers that are rich in tannins and leaf litter. These conditions create an ideal environment for these beautiful fish to exhibit their stunning colors and thrive in their natural ecosystem.
BreedingThe Cochu' s Tetra (Tetragonopterus cochu) is an egg scatterer, and breeding them is relatively uncomplicated. To maximize their breeding potential, a dimly lit aquarium with fine-leaved plants and soft, acidic water is necessary for successful hatching of the eggs. Well-conditioned females will deposit their eggs on the broadleaf plants' bottoms. However, the parents consume the eggs, making it essential to transfer the eggs to a separate grow-out tank immediately after spawning. After hatching, the fry can be fed with finely crushed flake food, infusoria, or newly hatched brine shrimp to ensure healthy growth and development.
Diet & feedingCochu' s Blue Tetras are not discerning eaters and are easily maintained with a diverse diet of high-quality flakes, granules, and micro pellets. Supplementing their diet with frozen, live, or freeze-dried foods, such as mosquito larvae, brine shrimp, tubifex, and bloodworms, is also recommended for their optimal health and vibrancy.
