Green Neon Tetra (Paracheirodon simulans) Fish Species Profile
The Green Neon Tetra is an excellent looking, peaceful fish that are relatively easy to take care of. However, this fish is not recommended for the community aquarium due to its small size and somewhat specific requirements. Ideally, these should be maintained alone or at most with small, non-aggressive fish.
The Green Neon Tetra is a social species and naturally forms schools meaning 8-10 of these fish is the minimum recommended purchase since the fish will be less shy and display more interesting behaviour.
They have some subtle variations that can be fun for aquarists who are looking for something a little bit different.
This Green Neon Tetra is similar in appearance to their closely related and better-known Neon Tetra. However, these are slightly smaller, slimmer and their red patch is less pronounced. their body has a silvery-greyish base. The bright turquoise-green colouration elongates throughout the fish's body on both sides. The only red-green colouration found in them is in the head, caudal fin and ventral area.

Origins of the Green Neon Tetra
It is native to the middle to upper Rio Negro River drainage as well as the Rio Orinoco system in the border region of Colombia and Venezuela, between San Fernando de Atabapo and the mouth of the Rio Meta in South America.
They inhabit blackwater environments that typically contain slow to moderately-flowing water with dense, overhanging, riparian vegetation and sandy substrates covered in leaf litter, fallen branches and tree roots.
The water is naturally acidic, of unimportant carbonate hardness and conductivity and stained a brownish colour due to the existence of humic substances released by decomposing organic matter.
In the home aquarium, they will happily accept dried foods. Still, like most fish they display its best health and colour when offered a varied diet which contains not only dried foods such as flakes and granules but also frozen and live foods such as Moina, bloodworm, daphnia and mosquito larvae.
