The Hyphessobrycon herbertaxelrodi or black neon Tetra are part of the great family Characidae. The genus Hyphessobrycon comprises several dozen species. Among them, we find the lemon grouse, Hyphessobrycon pulchripinnis, one of the popular aquarium species.
Contrary to what one might think, black neons are not part of the same genus as neon cardinalis (which belong to the paracheirodon kind.)
Anatomy of black neon
Black neons are small fish that reach 4 cm in adulthood. They have a fairly high body and laterally compressed. Their basic color is silver gray. The body has in its upper part a brilliant ray (which is worth its name neon), bluish to green, from the eye to the tail. Under this shining line another line of almost black color also separates the body in two.
The fins are transparent and the upper part of the eye is bright red. The female is rounder than the male.
Specific Care, Needs and Nutrition
Hyphessobrycon herbertaxelrodi are fish that live in the wild in South America and especially in Brazil. They swim in groups of hundreds of individuals. It is therefore essential to keep them in schools of at least 10 individuals. They are very peaceful and can cohabit with other species of characid or non-aggressive species.
Black neons are pretty lively fish, so you need a tank that has free areas for swimming and at least 1 meter in length. They also appreciate the vegetation, where they sometimes take refuge. Black neons occupy the surface and the middle of the aquarium and are not too shy. This is one of the few species that I own that does not spend time hidden in plants! They even have a very playful behavior: they present themselves in groups in the rejection of the filter and let themselves be pushed by the flow, one after the other.
Regarding water parameters, black neons require a fresh water (high maximum 15 ° GH), an acid PH: 6 to 7, and a temperature between 24 and 27 °. Finally, the black neon accept all kinds of food: flakes, small granules, daphnia, bloodworms and brine shrimp. Choose many small worms, too big they can not eat them.
Reproduction of Black Neon
You have to isolate a couple in a small tank of about 30 liters containing java mousse. The water must be very soft, about 4 ° GH, acid: Ph of 6 and a temperature of 26 °. Parents will be fed with live food. After the laying, you must remove the parents who might eat the eggs.
The tray must then be plunged into darkness (covering it), because the eggs do not tolerate light. The fry are born in 2 to 3 days and take refuge in the vegetation. We must now gradually get used to the light by discovering the tray gradually.
They will be fed infusoirs for a few days, then artemia nauplies or small fry feeds.
