Hyphessobrycon pulchripinnis , Ahl, 1937
Origin:Brazil, Rio Tocatins, Para region. Here the fish occupy the small slow flowing and densely planted rivers.
Etymology: Pulchripinnis= with beautiful fins.
Synonyms:None.Sometimes named Hemigrammus erythrophthalmus
First import:Germany, 1937, Scholze & Pötzschke.Mills and Vevers report 1933.
Description: See pictures.
Care:Similar requirements as Hyphessobrycon flammeus. Keep them in small schools, in a 60 cm tank or larger, with densely planted zones in the back of the tank. Some free swimming space in the front and in the upper regions of the tank, since Hyphessobrycon pulchripinnis usually inhabits the middle and upper regions. Lively and peacefull fish, suitable for the average community tank, although to get the fish to fully show their colors, peat filtration and a dark soil, combined with tempered light and frequent waterchanges are required. A bit of sunlight in the morning is highly appreciated by the fish.
Feeding:Omnivorous, all food is accepted.
Size:Up to 4.2 cm.
pH: 5.5-8.0 Hardness up to 25 dGH
Breeding: Productiv, up to 250 eggs. Raise the temperature to 24-28 degrees. Water should be at least slightly acidic, and have a hardness below 5 dGH. Eggs are deposited on a substrate like Myriophyllum, and will hatch in 24-50 hours. After the fish are done breeding, they should be removed immediately since afterwards they will start to eat the eggs.Fry should be fed infusoria as soon as they are free swimming(approx after 5 days). Not every pair is suitable for breeding. Egga and fry are reported to be sensitive, both require painfully pure water. Breeding tanks without gravel are advised.Fry grow slow.
Sexual dimorphism: Males have a black margin in the dorsal fin, females a bit more colorfull(more red).
Prices: Netherlands: 0.75-1€
Additional: If not fed a varied diet, Hyphessobrycon pulchripinnis looses some of the attractiv colors wildcaught fish exhibit.
