There are currently three recognized species in the Paracheirodons genus the neon tetra, cardinal tetra, and green neon tetra. Paracheirodons reach maximum overall length between 0.98” – 1.97” (2.5 to 5 cm), are of elongated tetra shapes, and share a distinctive iridescent blue lateral line.Īll of the fish in this genus are shoaling species that scatter their eggs and exhibit no parental care, often eating their eggs or fry in captivity. Genus: Paracheirodon, all species in this genus are native to the neotropic ecozone in the Orinoco and Amazon river Basins. Although there is some scientific debate surrounding the preferred name for this family, “characids” is preferred by scientists. Order: Characiformes are a subgroup of ray-finned fishes including characins and 17 other recognized families.įamily: Characidae is a family belonging to characiformes that hail from tropical and subtropical waters. This group makes up nearly half of all living vertebrates. These fish are characterized by the bony structures that support their webbed fins. Combined with their mass-farmed status, they’re much weaker fish than they were when Myers imported them so long ago.īut if you insist on keeping a shoal of neon tetras, we’ll tell you everything you need to know.ĭisclosure: we’re reader-supported! So if you buy a product I recommend, I might make some coffee money at no cost to you.Ĭlass: Actinopterygii are ray-finned fishes, which is a subcategory of boney fishes. Then they sit on a shop floor, usually in sparsely planted tanks under bright lights where they stress even more, and this surely lowers their immune system. There is mixed information about whether medication lowers fish’s immune systems, but even if not, the stress of transportation surely will. Neons are particularly susceptible to neon tetra disease (NTD) and bacterial diseases and are often shipped in medicated water from fish farms to prevent massive casualties. Making matters worse for most beginner hobbyists, they are shoaling fish that need to be kept in a group of at least six to be happy – but I’d recommend 10 or more – which most new fish owners simply aren’t told. Even after being established, any changes to their water chemistry, temperature, or tank can stress them to the point of illness. Although most neon tetras are hardy once established in a mature tank, the first few weeks of them being in their new home can be tough. There is one box they no longer check, however hardiness. They’re easy to house, active, colorful, easy to feed, and are tolerant to a wide range of water and temperature parameters. Maybe he did because, for most, neon tetras check a lot of boxes.
Myers ever imagined the small, colorful, peaceful fish from the Amazon and Orinoco Basins would be so popular. No doubt, it’s one of the most popular fish in the hobby.
Over 80 years later, roughly 1.8 million neon tetras are imported to the states on an average month, making neon tetras an estimated $2.1 million market per year. The first neon tetra was imported to the states in 1936 by ichthyologist Dr.
