Description

Species Background

Glo Pristella Tetras are fluorescent color variants developed from the X-ray Tetra lineage. These fish are fully tank-bred and maintain the hardy, adaptable nature of traditional Pristella tetras while displaying vibrant fluorescent coloration that intensifies under blue lighting.

They trace back to South American tetra ancestry and are well suited to stable community aquariums.

Behavior and Temperament

Peaceful, schooling midwater fish.

They should be kept in groups of at least 6, with 8–12 recommended for natural schooling behavior and stronger visual impact. They are active but non-aggressive and mix well in balanced community tanks.

They occupy the middle water column and provide constant motion.

Adult Size

Adults typically reach 1.75–2 inches.

Water Parameters

Temperature: 72–80°F
pH: 6.0–8.0
GH: 3–18 dGH
KH: 2–12 dKH

Tank-bred specimens adapt well to moderately hard and slightly alkaline water. Stability matters more than precision.

Diet

Omnivorous micro-predator.

• Quality flake or micro pellet
• Frozen daphnia
• Brine shrimp
• Micro foods
• Occasional live foods

Color intensity improves with varied feeding.

Tank Requirements

Minimum Tank Size: 20 gallons for a proper school

• Open swimming space
• Moderate filtration
• Gentle to moderate flow
• Plants or structure for security

They show strongest fluorescence under blue or mixed-spectrum lighting.

Suitable Tankmates

They coexist well with:

• Corydoras
• Rasboras
• Small peaceful barbs
• Dwarf gouramis
• Livebearers

Avoid large predatory fish.

Why They’re Popular
