Young adult Axolotls

Golden Starburst Axolotl (Ambystoma mexicanum – Golden Starburst Morph)

The Golden Starburst Axolotl is a stunning captive-bred colour morph of the Mexican Axolotl, prized for its bright golden-yellow body and shimmering speckled “starburst” pattern across the skin and gills. This unique morph combines the classic axolotl appearance with vibrant colouration, making it a true showpiece for cold-water aquarium setups.

Axolotls are fully aquatic salamanders known for their external feathery gills, gentle nature, and fascinating regenerative abilities.

Size & Lifespan

• Adult Size: 20–30 cm

• Lifespan: 10–15 years with proper care

• Temperament: Solitary, calm, slow-moving

Axolotls are best kept alone or with similarly sized axolotls due to their tendency to nip and their poor eyesight.

Appearance

• Bright golden to yellow body

• Sparkling, lighter “starburst” speckling across body and tail

• Pale pink to golden feathery external gills

• Wide head with a characteristic soft “smile” expression

• Smooth skin with subtle shimmer under lighting

Colour intensity can vary slightly depending on genetics and diet.

Water Parameters (Cold Water Species)

• Temperature: 16–18°C (do not exceed 20°C long term)

• pH: 6.5–8.0

• Hardness: Moderate hardness preferred

• Minimum Tank Size: 75–90L for one adult

They require clean, well-filtered water with very low flow. High temperatures are one of the most common causes of stress and illness.

Tank Setup

• Substrate: Bare bottom or fine sand (avoid gravel—impaction risk)

• Decorations: Smooth hides, caves, and driftwood

• Plants: Cold-water tolerant plants (optional)

• Filtration: Gentle flow; avoid strong currents

• Lighting: Low to moderate; axolotls prefer dim environments

Provide hiding spots and avoid sharp décor that could damage delicate skin and gills.

Feeding

Golden Starburst Axolotls are carnivorous.

Recommended diet:

• High-quality axolotl pellets

• Earthworms (excellent staple food)

• Frozen bloodworms

• Occasional raw prawn pieces

Feed juveniles daily and adults 2–3 times per week depending on size and condition.

Behaviour & Care Notes

• Poor eyesight; rely on smell and movement to locate food

• May snap at moving tank mates

• Sensitive to warm water and poor water quality

• Produce significant waste—strong filtration and regular water changes are essential

Important Considerations

• Not compatible with tropical fish

• Do not house with small fish (they may be eaten)

• Avoid strong currents or high temperatures

• Check local regulations before purchasing
