The Leopard Danio is a very striking and easily recognized variety of the Zebra DanioDanio rerio. This handsome little fish only reaches about 2 1/4 inches (6 cm) in length, but is spotted rather than stripped. Truly a 'leopard with spots', it has an overall brownish gold metallic color stippled with many bluish gray spots. This variety has also been developed with long flowing fins which is called the Longfin Leopard Danio. But in either any form it is very eye-catching and every bit as active and hardy as its progenitors, making it a great fish for the beginner or any other fish keeper.
This is one of the most popular and commonly available danios. It's been a long-time staple in the freshwater hobby, yet it has an unusual background. It was first described as Brachydanio frankei by Meinken in 1963. That was later changed to Danio frankei, but the actual origin of this fish is simply unknown. There were claims that it came from India or Thailand, but no type locality was ever known. Then some said it was a mutant strain developed in Czechoslovakia from the Zebra Danio while others speculated it could be a mutant strain of the Dwarf Danio or Spotted Danio Danio nigrofasciatus. Ultimately it was the result of fertile offspring from crossing B. rerio with B. "frankei that led to it now being generally accepted as a B. rerio variety.
These attractive little fish are hardy and prolific breeders, so they make ideal fish for the beginner. They do well in most community tanks and are a great addition to any collection of danios. Their behavior is pretty typical of the danio group, friendly enough, but definitely active and fast moving. They are a schooling fish and should be kept in a small group of at least three, ideally ten. A school of danios can be housed with most any community fish provided that the danios will not be eaten, and that the other fish aren’t startled by swift movement.
A school of these small lively fish are well suited to a smaller aquarium. A 10 gallon tank would be the minimum but 20 gallons is optimal. Their aquarium needs, care, and feeding are the same as their parentage. Like all the Zebra Danio varieties they can withstand an impressive range of water temperatures and conditions, and will generally do just fine without a water heater. They can be comfortable in temperatures down to the low sixties (F), but although they are not finicky about water conditions, it's best to not keep your aquarium at any extreme.
For a very attractive effect in your aquarium try a mixed school by combining the pretty Leopard Danio with some regular Zebrafish. A mix like this will provide a nice contrast of swift moving, darting color. Mixing even more varieties like the Golden Zebra Danio, Albino Zebra Danio, and Longfin Blue Danio works equally well and creates a really exciting effect. Don’t be surprised if the school spends a lot of time in the water flow of the filters or pumps as this is reminiscent of the swift moving waters found in their natural environment.
The Zebra Danio Danio rerio (previously Brachydanio rerio) was described by Hamilton in 1822. They are found in Asia from Pakistan to India and as far as Myanmar. The Leopard Danio was first described as Brachydanio frankei by Meinken in 1963. That was later changed to Danio frankei. There were claims that it originated from India or Thailand, but no type locality was ever known. It is now generally accepted and recognized as a B. rerio variety, with B. "frankei" being considered invalid. There are no known wild populations of this variety.
For a long time this danio's taxonomy was debated and divided. Some said it was a mutant strain developed in Czechoslovakia from the Zebra Danio D. rerio. Others further speculated it could be a mutant strain of the Dwarf Danio or Spotted Danio Danio nigrofasciatus (previously Brachydanio nigrofasciatus). Crosses of the Zebra Danio and B. "frankei" produced fertile offspring, which suggested they could be the same species. Then more recently an aquarist from Britain, Dr. George Cust, strengthened that notion when fertile second generation interbreeding hybrids showed a genetic ratio of 3:1 Danio rerio to D. frankei.
In nature the Zebrafish show a preference to the lower reaches of streams, canals, ditches, and ponds. However their habitat does vary depending on the time of year. During the wet season they are found in large numbers in seasonal pools and rice paddies where they feed and spawn, then the adults migrate back to the faster moving waters followed by the young when they reach maturity. The substrate of the clear freshwater streams is normally rocky and shaded, while the still waters are silty with dense vegetation. In the wild these fish are considered micropredators and feed on worms, small aquatic crustaceans, insects and insect larvae.
Scientific Name: Danio rerio
Social Grouping: Groups
IUCN Red List: NE - Not Evaluated or not listed - There are no known wild populations of this variety.
The attractive Leopard Danio, as well as the Longfin Leopard Danio, has a slender compressed body and there is a barbel at the end of each lip. The longfin variety sports long flowing fins and an extended tail. These are small fish reaching lengths of only up to about 2 1/4 inches (6 cm) in the aquarium. Their progenitors, the Zebrafish, are thought to be primarily an annual species in the wild. But captive bred varieties can have a lifespan of 3 to 4 years, and some have lived up to 5 1/2 years with proper care.
Longfin Leopard DanioLeopard Danio
This is a spotted version of the Zebra Danio. It has a golden or brownish background color with many bluish gray spots, both on the body and on the fins. When they swim at the top of the aquarium close to the light their gold bodies are very reflective, giving them a metallic appearance.
Size of fish - inches: 2.4 inches (5.99 cm)
Lifespan: 4 years - hey have an average lifespan of about 3 1/2 years, though some have lived up to 5 1/2 years with proper care.
Fish Keeping Difficulty
The Leopard Danio is a great choice for beginners and are great companions in a community aquarium. They tolerate water condition changes with out too many issues and can even be kept without a heater. They are usually are very easy to feed and get along with most tank mates. These fish will feed on just about anything that is offered, as long as it floats at the surface where they can readily consume it.
Aquarium Hardiness: Very Hardy
Aquarist Experience Level: Beginner
Foods and Feeding
Since they are omnivorous, these fish will eat most any prepared or live aquarium fare, though the food does need to float at the surface. They especially enjoy chasing after tubifex worms, whether living or freeze dried. A balanced diet for them would include flake or pelleted foods, plant based food, and occasional live prey. As with all danios, these fish are quite active and have high nutrient requirements, so select a flake food that will provide for their needs. These fish will do best when offered food several times a day, but offer what they can eat in 3 minutes or less at each feeding. If you feed only once per day, provide what they can eat in about 5 minutes.
Diet Type: Omnivore
Flake Food: Yes
Tablet Pellet: Yes
Live foods (fishes, shrimps, worms): Some of Diet
Vegetable Food: Some of Diet
Meaty Food: Some of Diet
Feeding Frequency: Several feedings per day - Offer only what they can consume in 3 minutes or less with multiple feedings per day.
These fish are not exceptionally difficult to care for, and mostly just need their water to be kept clean. At least 25 - 50% of the tank water should be replaced once a month. If the tank is densely stocked 20 - 25% should be replaced weekly or every other week. Aquariums are closed systems and regardless of size all need some maintenance. Over time decomposing organic matter, nitrates, and phosphate build up and the water hardness increases due to evaporation. Be mindful during maintenance that these fish will jump, so keep a close eye on them.
Water Changes: Monthly - It the tank is densely stocked the water changes should be done every other week.
The Leopard Danio is fairly hardy and will adapt to most aquarium conditions. It is a schooling species that will spend most time in the top and middle regions, particularly if there is open water or water current. Though a school of danios can be kept in a smaller aquarium, they will do best in about a 20 gallon size. Provide good filtration and the tank should be covered to prevent jumps.
These fish are most effectively displayed in tanks with subdued lighting and a dark colored fine gravel or sand substrate. They like a well planted aquariums and a variety of plants will make them feel safe. Dense tall plantings around the sides and back are great, but these fish prefer open water in the middle of the tank for swimming.
Minimum Tank Size: 10 gal (38 L) - Though a school of danios can be kept in a smaller aquarium, they will do best in about a 20 gallon size.

Hardness Range: 2 - 20 dGH
Water Movement: Moderate
Water Region: All - They will spend most of the time in the top and middle regions of the aquarium, particularly if there is open water or some current.
This Zebrafish makes a good community fish. It gets along well with others of its own kind and most other community species. Danios really need to be kept in a group to feel comfortable. They can be kept in groups as small as 3 individuals, but are happiest in a school of 5 or more. A pecking order may emerge in the school and they may tease each other and even engage in harmless fights, but nothing will come of it.
Select other tank mates with a similar in temperament that can keep up with the fast paced lifestyle of this fish. Danios have been known at times to harass other fish and tankmates that need a calmer environment can become stressed. Don't keep them with fish that can eat them or fish that demand a peaceful aquarium. Also, those with long flowing fins are a temptation too great for any fin nipper to resist, so pick other tank mates carefully.
Temperament: Peaceful - They are good community fish with other fish that are also fast moving.
Same species - conspecifics: Yes - They are best kept in groups of 5 or more.
Peaceful fish (): Safe - These are a very lively fish so pick tankmates that will not be bothered by it.
Semi-Aggressive (): Monitor
Aggressive (): Threat
Large Semi-Aggressive (): Threat
Large Aggressive, Predatory (): Threat
Slow Swimmers & Eaters (): Safe - Large schools of these very active fish may make calmer tankmates nervous.
Shrimps, Crabs, Snails: Safe - not aggressive
Sex: Sexual differences
Males are more streamlined and slim in body shape, while mature females are plumper.
Breeding / Reproduction
The Leopard Danios are very easy to breed, and it may even occur on accident. Two fish will form a breeding pair which they often keep for life. If you wish to retain the young, the breeding tank should be empty except for a two inch layer of large glass marbles, 1/2 to 1 inch in diameter. Add the female to the tank and let her settle for about a day before adding the male. When they are both in the tank, adding a few cups of cold water will cause the courtship to begin.
If conditions are favorable, the female will release her eggs in open water and the male will fertilize. The eggs will then sink to the bottom and fall through the marbles, out of their parents reach. The fry will emerge from the marbles after about 7 days. At that time or before, parents should either be removed or kept constantly well fed. See the description of breeding techniques in: Breeding Freshwater Fish: Barbs. Also see Fish Food for Fry for information about types of foods for raising the young.
Ease of Breeding: Easy
Leopard Danios are extremely hardy and disease is not usually a problem in a well maintained aquarium. The finnage of the the longfin variety can be extra sensitive to fin rot and other diseases affecting that region. Fins may also be damaged during the normal activity of this fish. If large tears are noticed it may be wise to add a fin repair medication. With any additions to a tank such as new fish, plants, substrates, and decorations there is a risk of introducing disease. It's advisable to properly clean or quarantine anything that you want add to an established tank prior to introduction, so as not to upset the balance.
These fish are very resilient but knowing the signs of illness, and catching and treating them early makes a huge difference. An outbreak of disease can often be limited to just one or a few fishes if you deal with it at an early stage. The best way to proactively prevent disease is to give your fish the proper environment and a well balanced diet. The closer to their natural habitat the less stress the fish will have, making them healthier and happy. A stressed fish will is more likely to acquire disease. For information about freshwater fish diseases and illnesses, see Aquarium Fish Diseases and Treatments.
The Leopard Danio and Longfin Leopard Danio are both readily available and inexpensive. They can be found in pet stores, on the internet, and through mail order.
Jason Remigio III - 2009-01-27 I have kept Longfin Leopard Danios in sets of 5 for 3 years. They are very good to start with. I don't know why they would go to the bottom of the aquarium under the gravel along with its other buddies. They have been disappearing one at a time after 2 and half years already.
S. A. - 2009-08-16 I started with just two longfin leopard danios and luckily got a male and female. When the females belly looked as if she was pregnant I moved both to a 3 gallon tank for about 3-4 days and when she went back to normal size I then moved them both back to the 50 gallon with my other tropicals. I now have about 80-90 babies. Almost microscopic at first, and about the size of a newborn guppy now after almost 2 months. Love these fish, a lot of fun to watch play.
paige - 2012-02-14 I have 4 leopard danio and one of them has just died so now I have 3 but I would like to breed them but I don't know if I have too many or unless they fight a lot and that's why one of them died, I think. Help me
