Omnivorous: all forms of food are accepted.
Behavior
Behavior
What kind of behavior does the Green neon have?
Pacific with all, it can even be shy. Like all species of the genus, it is gregarious and must imperatively be kept with a shoal. It will feel safer and can move serenely in the aquarium.
Cohabitation
Cohabitation
Who can live with the Green neon?
A community aquarium is accepted in cohabitation with calm and non-aggressive fish of the same size as him. Indeed, the green neon could serve meals to large fish.
Ideally, keep it with other South American species, such as other Hemigrammus or Hyphessobrycon species, crayfish, Apistogramma cichlids, Corydoras and small Loricariidae.
In a more general aquarium, it can also be combined with small Rasboras or West African dwarf cichlids such as Pelvicachromis species.

How to breed the Green neon?
Its breeding is possible.
Place in a spawning tank (15L or 4Gal) equipped with a protective grid and tufts of fine-leaved plants (Java moss), a male and a female. Temperature 24/26°C or 75/79°F and pH 6. The lighting will be dim. The water must be new and filtered on peat. Before spawning, separate the sexes and stimulate spawning by feeding adults abundant live prey. Introduce a couple in the egg-laying bin in the evening and spawning will normally take place the next morning.
As soon as the eggs appear, remove the parents. A laying can range from 100 to 200 yellowish eggs. The incubation lasts 24h at 26°C or 79°F Fand takes place in a half-darkness. 50% water change every 15 days.
Fry food: infusoria for 2 days, nauplies of Artemia and Cyclops.

Which aquarium for the Green neon?
A biotope will be easy to configure. First, the substrate, composed of river sand, that you can line with dried leaves (beech or oak). These leaves will colour the water with a colour slightly similar to that of tea. Replace these leaves before they rot.
Also have turtle roots or driftwood (watch out for the stability of your arrangement) in the aquarium.
As far as plants are concerned, you can choose what you like as long as the final result is lush, but with enough room for swimming.
Once well acclimated, the green neon likes regular water changes.

It is a fragile fish sensitive to pharmaceuticals and parameter changes.
A very mild acclimatisation will also prevent the appearance of disease.
