Description:
Danios (Danio rerio varieties) are lively, fast-swimming freshwater fish prized for their energy, hardiness, and striking patterns. This assortment may include a mix of Longfin and Shortfin Zebra Danios, along with Leopard varieties, offering a beautiful combination of classic stripes, spotted patterns, and flowing fins. Their constant movement and shimmering colours make them a standout feature in any aquarium.
Zebra Danios display bold horizontal blue and silver striping, while Leopard Danios feature a unique spotted pattern with gold, green, and dark markings. Longfin varieties add an extra level of elegance, with extended, flowing fins that trail behind them as they swim. When kept together in groups, these different varieties create a dynamic and visually engaging display.
Males are typically slimmer and may show slightly more intense colouration, while females are rounder, especially when carrying eggs. Regardless of variety, all Danios are highly active schooling fish that bring movement and life to the upper and mid levels of the aquarium.
Known for their adaptability, Danios are incredibly hardy and tolerant of a wide range of water conditions. Their easy care requirements and energetic shoaling nature make them an excellent choice for both beginners and experienced aquarists.
Temperament:
Danios are peaceful, social fish that thrive in groups of six or more. Their fast-paced swimming and playful behaviour make them a great addition to community tanks, though their activity level means they are best kept with similarly active species.
They are non-aggressive and rarely bother other fish, but their energetic nature can sometimes overwhelm slower or more timid tank mates. Providing ample swimming space and keeping them in groups of 4–8 or more, this helps them display their natural shoaling behaviour and keeps stress to a minimum.
Diet:
Danios are omnivorous and highly adaptable feeders. In the wild, they consume small insects, larvae, and plant matter. In the aquarium, they readily accept high-quality flakes such as Xtreme Community Crave or micro pellets as a staple diet.
To keep them in peak condition, supplement their diet with live or frozen foods such as brine shrimp, daphnia, and bloodworms. Due to their fast metabolism and active nature, they benefit from smaller, more frequent feedings throughout the day, although this is the case, in our fish room we still skip a day or two to encourage digestion, please visit our diet tab for more information.
Breeding Behaviour:
Danios are egg-scattering fish with straightforward and rewarding breeding behaviour. Males will actively chase females during courtship, especially when conditioned with high-quality foods. Females become noticeably rounder when carrying eggs.
Spawning typically occurs over fine-leaved plants, moss, spawning mops, we use coconut husk layed out in the bottom of fish tanks where eggs are scattered and fertilised as they fall beneath where adults cannot reach them. This is because adults will readily consume eggs whenever possible, it is recommended to remove them after spawning or provide plenty of cover such as plants, leaf litter, or spawning media to protect the eggs.
Eggs usually hatch within 24–48 hours, with fry becoming free-swimming shortly after. Newly hatched fry require very fine foods such as infusoria, baby powder or Xtreme Nice Crumble, then gradually progressing to baby brine shrimp or finely crushed food as they grow.
To encourage breeding, maintain clean water, provide dense plant cover, and offer a varied, high-quality diet to keep adults in optimal condition.

Acclimation Guide:
- Float the Bag: Place the unopened bag in your tank and let it float for 15–20 minutes. This lets the water inside the bag slowly match your tank’s temperature.
- Turn Off the Lights: Keep the aquarium lights off during this process. It helps keep things calm and prevents sudden temperature changes.
- Add a Bit of Tank Water: After floating, carefully open the bag and pour out about half the water into a sink or bucket (not into your tank). Then, slowly add small amounts of your tank water into the bag over 15–20 minutes. This helps your fish adjust to the new water conditions.
- Gently Move the Fish: Use a fish net to gently move your fish from the bag into the tank. Try not to pour the bag water into your tank — this helps keep your aquarium clean and healthy.
- Watch and Wait: It’s normal for fish to hide or act a bit shy at first. Keep an eye on them, and avoid doing a water change for the first 24 hours to give them time to settle in.
- Feeding Behaviour: New fish may not eat any food for the first 12-24 hours whilst it is settling into its new environment, please allow some time before feeding as the food may go to waste.

Tank Requirements - Quick Overview
If your aquarium is new, it may not be fully cycled yet. Newly set up tanks benefit from being fully cycled before adding fish, this process helps your new fish stay happy and healthy. Depending on your tank size, cycling can take up to 4–6 weeks or even longer, but there are ways to speed up this process to just a few days! If your tank has already been running for a while, you’re already good to go! Not sure what cycling means? Check out our guide on The Nitrogen Cycle for an easy explanation on what it is, and why it is important for your aquarium to thrive.

Frequently Asked Questions
How many Danios should I keep together?
Danios are shoaling fish and should be kept in groups of at least 6. Larger groups of 8 or more encourage natural shoaling behaviour, reduce stress, and make for a far more impressive display. Lone or small groups of Danios can become skittish or nippy.
Are Danios good for beginners?
Yes, Danios are one of the best beginner fish available. They are extremely hardy, tolerant of a wide range of water conditions, and easy to feed. Their active nature also makes them engaging to watch, making them a great first fish for new aquarists.
What temperature do Danios need?
Danios are adaptable and can thrive in both cooler and tropical setups between 18°C and 24°C. Unlike most tropical fish, they do not strictly require a heater, though a stable temperature is always recommended. Avoid sudden temperature fluctuations.
What level of the tank do Danios swim at?
Danios are active mid to top level swimmers. They rarely venture to the bottom of the tank, which makes them excellent companions for bottom dwellers like Corydoras or Bristlenose Plecos without competing for the same space.
Do Danios need a lid on their tank?
Yes, a secure lid is essential. Danios are strong, fast swimmers and are known jumpers, especially when startled or during active feeding. Even a small gap is enough for them to escape, so ensure your tank is well covered at all times.
Will my Danios outcompete other fish for food?
Danios are fast, active feeders and can outcompete slower or more timid tank mates at feeding time. If keeping them with less competitive fish, target feed bottom dwellers with sinking wafers and consider feeding in multiple spots simultaneously to ensure everyone gets their share.
What do Danios eat?
Danios are omnivores and readily accept a wide variety of foods. A high-quality flake or micro pellet such as Xtreme Community Crave makes an excellent staple. Supplement regularly with live or frozen foods such as brine shrimp, daphnia, and bloodworms to keep them in peak condition.
Can Danios be kept with long-finned or slow fish?
Use caution. Danios can be fin nippers, particularly with slow-moving or long-finned fish such as Bettas, Angelfish, Gouramis, and Discus. They are best kept with similarly active species that can hold their own. Always monitor for nipping behaviour when introducing new tank mates.
Will Danios eat their own eggs or fry?
Yes. Danios are egg scatterers and will readily consume their own eggs and fry if given the opportunity. If breeding, remove adults after spawning or provide dense plant cover, spawning mops, or leaf litter to protect eggs. Fry require very fine foods such as infusoria or baby powder food initially.
Can small Danios be eaten by larger fish?
Yes. Danios only reach approximately 5cm, making them vulnerable to any fish large enough to fit them in their mouth. Avoid housing them with large predatory fish such as Oscars, Jack Dempseys, Arowanas, or large Cichlids. Stick to similarly sized, peaceful community fish.
A Note on Our Fish:
Fish may vary slightly in colour, size, and pattern from those pictured or shown in images and videos. This is natural across all fish, whether bred in-house, locally sourced, or imported, as individual variation is part of what makes each fish unique!
Every fish is quality checked for health, behaviour, and appearance before leaving our fish room. Fish that are dispatched as juveniles will grow into their adult size and colouration over time with a good balanced diet and proper care.
