Blue Tetra

The Blue Tetra is a small characin known for the vivid blue sheen along its body—so intense that some fish are mistaken for dyed specimens. Despite its small size, it's a highly active swimmer that thrives in a lively shoal. During feeding time or in a cramped tank, Blue Tetras can nip at other fish's fins, so tankmates and swimming space need some thought. A dark substrate paired with floating plants makes their blue coloring really pop. Adults reach about 5cm, and this species is generally considered suitable for intermediate-level keepers.

About Blue Tetra

Blue Tetra: a small characin with vivid blue coloring and an active, shoaling nature. May nip fins if crowded or underfed. Adults reach about 5cm; suited to intermediate keepers.

7 things to know before welcoming a Blue Tetra

1Vivid Blue Coloring
The Blue Tetra's body shines with an intense blue that's so vivid, newcomers sometimes assume it's been dyed. Paired with a dark substrate, this coloring stands out even more.
2Small but Very Active
Despite its small size, this fish swims energetically throughout the tank. Choose a tank with plenty of open swimming space to keep it comfortable.
3Watch for Fin-Nipping
At feeding time or in a cramped tank, Blue Tetras may nip at other fish's fins. Avoid overcrowding and long-finned tankmates, and make sure feeding amounts are adequate.
4Keep in a Group
Keeping a proper shoal rather than just one or two fish spreads out nipping behavior and reduces stress on any single tankmate. Consider bringing home a small group together.
5Ideal Tank Layout
A dark substrate combined with floating plants really makes the blue coloring pop. Adding some shaded spots also helps the fish feel secure.
6Adults Reach About 5cm
Blue Tetras stay compact, reaching only about 5cm as adults. Still, because they're such active swimmers, choose a tank sized for their activity level, not just their body size.
7Suited to Intermediate Keepers
This species is generally considered suitable for intermediate keepers who have some experience with water quality management and tankmate selection. Make sure your tank is fully cycled and stable before bringing them home.
