X-ray tetra care guide

X-ray tetra tank size

Provide a minimum tank length of 60 cm for a shoal, with planted shelter and an open swimming area. Mass-produced X-ray tetras adapt to many layouts but show better colour in planted surroundings than in very bare aquariums.Provide a minimum tank length of 24 in for a shoal, with planted shelter and an open swimming area. Mass-produced X-ray tetras adapt to many layouts but show better colour in planted surroundings than in very bare aquariums.^[1][2]

Sand, branching wood and dried leaves create shelter under dim light. Replace deteriorating leaves before accumulated decay fouls the water in your aquarium.Sand, branching wood and dried leaves create shelter under dim light.

X-ray tetra water parameters

Keep 24–28 °C, pH 6.0–7.5 and hardness 2–15 dGH, within the shared care ranges. The species experiences seasonal changes in dissolved minerals in nature; its adaptability is not a reason to neglect stable clean aquarium water.Keep 75–82 °F, pH 6.0–7.5 and hardness 2–15 dGH, within the shared care ranges. The species experiences seasonal changes in dissolved minerals in nature; its adaptability is not a reason to neglect stable clean aquarium water.^[1][2]

Use a mature filter and keep ammonia and nitrite undetectable; test weekly and after stocking changes. Change a quarter of the water each week with conditioned replacement water, and preserve filter bacteria by rinsing media in removed tank water.Use a mature filter and keep ammonia and nitrite undetectable; test weekly and after stocking changes.

Feeding x-ray tetras

Feed once daily with only the amount eaten within a few minutes; excess food decomposes and adds toxic waste to the water. Offer small flakes or granules and rotate live or frozen daphnia and Artemia; in nature this fish eats mainly tiny invertebrates.Feed once daily with only the amount eaten within a few minutes; excess food decomposes and adds toxic waste to the water.

Very large or boisterous tank mates can outcompete peaceful X-ray tetras, so observe feeding access rather than assuming every fish has eaten in the display.Very large or boisterous tank mates can outcompete peaceful X-ray tetras, so observe feeding access rather than assuming every fish has eaten in the display.^[1][2]

X-ray tetra behaviour

Keep a minimum group of six; ten or more is preferable when the tank has space for them. This is a peaceful shoaling fish whose company should include its own species; a lone fish does not meet its social needs.Keep a minimum group of six; ten or more is preferable when the tank has space for them.

Peaceful is a species-level description; observe changes in behaviour rather than assuming an individual cannot nip or chase. Adult length is approximately 4.5 cm in standard length.Peaceful is a species-level description; observe changes in behaviour rather than assuming an individual cannot nip or chase.

Pristella tetra and water goldfinch are alternative common names; the selectively bred golden strain is semi-albino and needs the same basic care. The species is commercially bred in large numbers and considered a hardy beginner choice once basic aquarium needs are met.Pristella tetra and water goldfinch are alternative common names; the selectively bred golden strain is semi-albino and needs the same basic care.

Breeding x-ray tetras

Spawning is achievable but raising the very small fry is more demanding; a dedicated dim aquarium gives better control than a mixed community.Spawning is achievable but raising the very small fry is more demanding; a dedicated dim aquarium gives better control than a mixed community.^[1]

Fine-leaved plants or spawning mops provide egg sites, and mesh can prevent adults from reaching fallen eggs; remove parents once eggs appear.Fine-leaved plants or spawning mops provide egg sites, and mesh can prevent adults from reaching fallen eggs; remove parents once eggs appear.^[1]

Use gentle air-driven sponge filtration and keep eggs and early fry shaded because they are light sensitive.Use gentle air-driven sponge filtration and keep eggs and early fry shaded because they are light sensitive.^[1]

Eggs hatch in roughly 24–36 hours and fry become free swimming three to four days later; start with infusoria-sized foods before microworm or Artemia nauplii.Eggs hatch in roughly 24–36 hours and fry become free swimming three to four days later; start with infusoria-sized foods before microworm or Artemia nauplii.^[1]

X-ray tetra health problems

Ich is caused by Ichthyophthirius multifiliis; white grains on skin or fins, rubbing and faster breathing are possible signs. Quarantine incoming fish for 30 days; separate nets and siphons prevent moving sticky ich cysts between aquariums. Seek prompt diagnosis if signs appear.Ich is caused by Ichthyophthirius multifiliis; white grains on skin or fins, rubbing and faster breathing are possible signs.

Bacterial fin disease can show ragged or blood-streaked fins, ulcers or sores; stress makes fish more vulnerable to infection. Reduce bacterial disease risk by maintaining good water quality and removing sources of injury or aggression; observe symptoms before choosing treatment.Bacterial fin disease can show ragged or blood-streaked fins, ulcers or sores; stress makes fish more vulnerable to infection.

Fungal cotton-wool disease produces pale fluffy growth over damaged tissue; injury, rough handling and poor conditions let fungi overcome the protective mucus. Prevent fungal entry by handling fish gently, avoiding sharp decor and maintaining water quality; fluffy growth needs prompt assessment rather than guessing medication.Fungal cotton-wool disease produces pale fluffy growth over damaged tissue; injury, rough handling and poor conditions let fungi overcome the protective mucus.

Male or female?

Mature females are normally larger and stockier than males; breeding females become fuller with eggs, while males in breeding condition show stronger colour. These sexing cues apply to mature fish and relative body condition; the golden ornamental strain is a colour form, not a sex.Mature females are normally larger and stockier than males; breeding females become fuller with eggs, while males in breeding condition show stronger colour.
