The Blue Neon Tetra (Paracheirodon simulans), also known as the Green Neon Tetra, is a small schooling fish known for the brilliant blue-green stripe that runs nearly the entire length of its body. Compared with the more familiar Neon Tetra, Blue Neons are smaller, more streamlined, and have a cleaner metallic coloration that can look incredible in a planted aquarium.
Their size makes them especially impressive in larger groups. Rather than relying on a single fish for color, a school creates a shifting band of blue across the aquarium as they move together through plants and open water.
Care Information
Scientific Name:Paracheirodon simulans
Adult Size: About 0.75–1 inch
Temperament: Peaceful
Swimming Level: Middle
Diet: Omnivore
Recommended Group: 8+, with larger schools preferred
Temperature: 75–82°F
pH: Approximately 5.0–7.0
Difficulty: Easy to Moderate
Lifespan: Approximately 3–5 years
Best For: Planted aquariums, peaceful community tanks, nano aquariums, blackwater-inspired setups, and larger display schools.
Blue Neon Tetras appreciate a mature, stable aquarium with plenty of plant cover and some open swimming space. Darker substrates and backgrounds can make their metallic coloration especially noticeable.
Because of their small size, foods should be appropriately sized. Quality micro pellets, finely crushed flakes, and small frozen or live foods all work well.
They should be kept with peaceful tankmates that aren't large enough to view them as food. While a small group can be maintained, their behavior and visual impact are much better in a substantial school.
The Reserved Aquatics Standard
Blue Neon Tetras are a step away from the ordinary community tetra. Their smaller size and intense blue-green coloration make them a variety we specifically seek out when good specimens are available.
We look for well-conditioned fish with full bodies, clean fins, strong metallic coloration, and active schooling behavior. When we find a group worth bringing in, they earn a place in our reserves.
Quality Worth Keeping.
