Hyphessobrycon heliacus , Moreira, Landim & Costa, 1988
Origin:Brazil, Mato Grosso, upper rio Tapajós basin. This river ends in tte amazon river near Santarem.
(ray-finned fishes) Order: Family:
Description: This new species is distinguished from other currently recognized Hyphessobrycon species by the combination of an enlarged caudal spot, the golden body coloration in life, the elongate filamentous dorsal and pelvic fins, thickened anal fin rays, and the absence of anal fin lobe. These last three characteristics are present only in mature males. Fully grown males show a reddish color in the fins.
Care: These fish prefer neutral to slightly acidic water. In the wild it inhabits slowly flowing relatively clear water with a depth of 0.10 to 2 meter. Temperature 24 degrees in the rainseason, 29 during the summer. Soft water, dGHbelow 8 and a pH between 6.5 and 7. In nature they inhabit regions with lots of aquatic plants, and submersed swamps with a dark muddy soil. To fully bring out the color in this beautiful little fish it is recommended to provide them with a similar environment, some densely planted areas in the tank in combination with a dark soil will do fine. The fish should be kept in larger groups in not too small tanks. If kept with too few they will suffer from stress, where if kept in larger groups with some peacful co-inhabitants they will show themselves more often. Try to keep at least 8 of them together, but it's better to have a larger group..
Temperature: 23 - 27°C
Omnivorous, Flake, frozen and live food. The food should be small enough.
