Another season, come and gone! Today marks the longest day of the year here in the Northern hemisphere, and I for one am ready for the ups and downs summer brings! I’m talking fruit and berry season, people! But we aren’t the only creatures who enjoy these sweet delights. Pick your berries, but keep ‘em out of reach, for a certain group of hymenopteran kitchen pests are gearing up to take over! In honor of the official start of summer 2019, take a look at a few South American Tetras named for summer staples: Hyphessobrycon sp. “Red Cherry”, Hyphessobrycon wadai, and Hyphessobrycon myrmex.
Scientific NameHyphessobrycon sp.
Common Name“Red Cherry”
Temperature / pH78°F – 84°F / 6.0 to 7.0 pH
Native Locationthe Guapore River basin in Paraguay
As stunning as the plump, sweet, red tree fruits, H. sp. “Red Cherry” is collected from the Guapore River basin in Paraguay. Reaching about 2 inches in length, these Red Cherry Tetras exhibit the typical arrow-like characin body shape with light red coloration over their entire bodies and bright red fins and noses. Males tend to be slightly smaller in body with brighter coloration. These tetras are great for South American community aquaria, and should be kept in tanks with sandy substrate, lots of hardy aquatic vegetation like Anubias, Bolbitis, Java Fern, and Crypts, multiple hiding places like driftwood, rock piles, pots, or caves, and plenty of open swimming space in the center of the tank. Shoaling by nature, they should be kept in conspecific groups of at least 5 with a female dominant sex ratio, and are happily housed alongside other South American Characins, peaceful Catfish, and Dwarf Cichlids that tolerate similar water conditions. This species seems to be opportunistically omnivorous, and can be fed just about any high-quality tropical flake or granule with some vegetal component, and regular live and frozen invertebrate snacks. Tank waters should be maintained with temperatures between 78 and 84°F, a pH of 6.0 to 7.0, and a hardness of 215 ppm or less.
Scientific NameHyphessobrycon wadai
Common NameBlueberry Tetra
Temperature / pH70°F – 78°F/ 5.5 to 7.5 pH
Native Locationupper Rio Tapajos
Even more striking than the bush berries they’re named for, H. wadai is a Hyphessobrycon congener who calls the upper Rio Tapajos home. Known as “Blueberry Tetras” in the aquarium trade long before earning their scientific name, this characins reach just under 1.5 inches and exhibit beautiful dark, shiny, purple-blue bodies with bright red-purple fins. With a preference for clear, flowing streams, this species does best in aquaria with some degree of current from filtration systems or air pumps. Otherwise, tanks should be furnished with soft, sandy substrate, scattered, variably-sized, water-worn rocks, driftwood, and hardy plants. Opportunistic omnivores, wild specimens have been found to consume filamentous algae, organic detritus, and various terrestrial and aquatic invertebrates. In captivity they should be fed balanced diets of high-quality flake and granules, algae, spirulina, and frequent live and frozen invertebrates. Another schooling tetra, they should be kept in conspecific groups of at least 5, alongside other South American Characins, Dwarf Cichlids, and peaceful Catfish. Blueberry Tetras do best in waters with temperatures of 70 to 78°F, a pH between 5.5 and 7.5, and hardness under 215 ppm.
Scientific NameHyphessobrycon myrmex
Common NameAnt Tetra
Temperature / pH72°F – 80°F / 5.0 to 7.5 pH
Native Locationthe Rio Tapajos basin of Brazil
