The Golden X-Ray Tetra is proof that sometimes the smallest details make the biggest impact. This variant of the classic X-Ray Tetra shares the same translucent charm but adds a warm, metallic sheen across the body. Against this soft golden backdrop, the bold fin accents — yellow, black, and white stripes, paired with a reddish tail glow — stand out even more dramatically.

Rather than overwhelming the tank, Golden X-Ray Tetras bring a subtle, sunlit shimmer that enhances the colors of other fish and plants. They’re the perfect balance of understated elegance and quiet brilliance.

The Art of Schooling

Like their wild-type cousins, Golden X-Ray Tetras thrive when kept in groups of at least six. Their schooling behavior turns into a moving display of gold flashes and fin stripes weaving gracefully across the tank. They create harmony in community aquariums, often acting as the steady rhythm that allows brighter centerpiece fish to shine.

A golden shimmer in motion — the school moves as one, each fish catching the light like a fleck of sun across the water.

Aquascaping with Subtle Elegance

Designing an aquarium for Golden X-Ray Tetras is about letting their glow complement the environment. Their translucent golden bodies reflect the aquascape around them, becoming part of the design itself.

• Plants as Contrast: Lush greens from Vallisneria, Hygrophila, or Anubias bring out their golden hue, while shaded areas let their translucent frames shimmer softly.

• Hardscape for Drama: Driftwood and darker stones enhance the golden glow and create definition, helping their fin markings appear crisp and bold.

• Botanicals for Mood: Indian Almond Leaves, alder cones, or lotus pods release tannins that tint the water amber, echoing their natural habitat and deepening their golden sheen.

• Lighting Choices: Gentle lighting makes them glow warmly, while too-bright setups can wash out their subtle colors. Soft light with a dark substrate creates a gallery effect that highlights their shimmer.

• Open Space for Flow: As active schoolers, they need horizontal swimming space. An aquascape with structured plants and decor around the edges leaves the center clear for their fluid schooling movements.

Together, these elements create a living canvas where the Golden X-Ray Tetra becomes both the subject and the highlight.

Origin

The wild X-Ray Tetra (Pristella maxillaris) is native to northern South America, found in the Orinoco Basin and coastal rivers of Venezuela, Guyana, Suriname, French Guiana, and Brazil. In these environments, their translucent bodies help them blend in with vegetation and dappled light for camouflage.

The Golden X-Ray Tetra is a captive-bred variant developed to enhance the body’s natural sheen, giving it a golden glow. While selectively bred, it retains the same temperament, hardiness, and schooling behavior that make the species so beloved in the aquarium hobby.

Why You Should Keep Them

• Peaceful, hardy, and beginner-friendly.

• Unique golden sheen with classic fin markings.

• Active schoolers that bring movement and balance to community tanks.

• Adaptable and compatible with most community species.

Why You Might Not

• They can appear understated compared to more vividly colored species.

• Require groups of six or more to feel secure.

• May snack on shrimp fry if available.

Feeding the Golden Canvas

Golden X-Ray Tetras are omnivores that thrive on variety. A base of high-quality flakes or micro pellets supports health and color, while frozen or live foods such as brine shrimp, daphnia, and bloodworms bring out their natural glow and keep them active.

Shrimp Compatibility

Safe with adult Neocaridina or Amano shrimp, though small shrimp fry may be eaten. Dense moss or plant cover helps protect young shrimp if you want to keep both in the same setup.
