Leopard Danio (Danio Rerio)

The Leopard Danio is a very hardy, friendly, peaceful and attractive fish. They make a great addition to any community aquarium, especially alongside other Danio species, suitable for any fish keepers level.

This fish is a colour morph of the Zebra Danio and displays a lovely golden brown metallic colour dotted with greyish-blue spots. They have a barbel at the end of each lip. A long-finned version of this fish has been developed that sports long, flowing fins and an extended tail. In both forms, they are eye-catching active fish.

Feeding

In the home aquarium, the Leopard Danio will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

Males are thinner and have a streamlined body shape, and their colours are more intense than females, whereas mature females are plumper and much duller than males.

Frequently asked questions

Are Leopard Danios shoaling fish?

Leopard Danios are a shoaling species; therefore, it would be better to keep them in groups of 6 or more individuals. These Danios will spend the majority of their time in the middle and top regions of the aquarium, especially if there is open water or water currents.

How big do Leopard Danios get?

Leopard Danios can grow up to 6 cm in length, with the males usually being slimmer than the more plumper females.

How long do Leopard Danios live?

Leopard Danios usually live for around three and a half to 4 years; however, if they are given the appropriate care and attention, they can live for as long as five and a half years.

What do Leopard Danios look like?

Leopard Danios have a slender, compressed body and a barbel at the end of each lip. They also have a brownish-gold metallic colour body contrasted with bluish-grey spots both on their body and fins. There has also been a variety developed with long, flowing fins and an extended tail which they call the Longfin Leopard Danio.

What should you feed Leopard Danios?

Leopard Danios will eat practically anything you give them; however, their food does need to float at the surface. These fish enjoy chasing after live or freeze-dried food. These fish need a balanced diet, including flake or pelleted foods alongside plant-based food as well as the occasional live prey. Like all Danios, this species is very active and has high nutrient requirements; therefore, choose a food that can provide for their needs. Leopard Danios will do best when offered food several times a day but make sure you only give them what they can consume in 3 minutes or less at each feeding.

What size aquarium is suitable for Leopard Danios?

A school of Leopard Danios are acceptable in a smaller aquarium that holds around 45 litres of water. However, 90 litres would be far more sufficient as they are very active and love to swim around.
