Red Phantom Tetra (Hyphessobrycon sweglesi)
The Red Phantom Tetra is a peaceful and active freshwater fish popular in the aquarium hobby. Native to the Orinoco River drainage basin in South America, this species is known for its beautiful reddish-orange iridescent body and distinctive black markings.
Like most Tetras, we recommend keeping these fish in groups of 5 or more to ensure they feel safe and display their natural school behavior. They look especially stunning in a planted tank environment.
These fish are relatively easy to care for as long as they are introduced to a mature, cycled tank. They can acclimate to a wide range of parameters, including temperature and water hardness, once established.

I bought a group of five Red Phantom Tetras for my 20-gallon planted tank. They’ve been active and colorful since arrival. The fish seem to enjoy the school behavior and stay calm around other community fish. Easy to maintain once the tank is cycled.

The fish arrived healthy and looked vibrant. I kept them in a planted tank with java fern and moss. They swim in tight schools and add a nice visual appeal. Just make sure the tank is mature before introducing them.

Great addition to my community tank. The red and black markings are striking. I kept them in a group of six and they’re very active and peaceful. No aggression observed, even with other tetras.
