The Red Phantom Tetra (Hyphessobrycon sweglesi) is a peaceful, schooling freshwater fish known for its translucent, deep-red coloration and distinctive black humeral spot. Originating from the Orinoco River basin in South America, this species is highly valued in the aquascaping community due to its gentle temperament and striking visual contrast against green aquatic foliage.

Note for Beginner Aquarists: Red Phantom Tetras are durable, low-maintenance fish that adapt well to community aquariums. Because they are natural schoolers, keeping them in groups of six or more reduces stress and encourages vibrant coloring and active swimming behavior.
