These species have long fins and an extended tail. They have a golden plus brownish body-color with so many bluish-gray spots, like that of a leopard, of course!

As for the size, the average length of Longfin Leopard Danios is about 2 inches at approximate. However, they can grow at a maximum of 2.4 inches depending on the habitat that they are kept in. So, if you want your fish to rise above average, you should make sure that your Longfin Leopard Danios have a fish-friendly environment.
Both the male and female Leopard Danios have two pairs of barbel and similar spots on their bodies, but the females are usually larger than the males. The male Danios appear more torpedo-shaped, while the females may seem to have a larger belly—moreover, the females’ belly balloons when it’s filled with eggs.
The Longfin Leopard Danios are the most peaceful, active, and also a great starter fish for most community tanks. The behavior of these species is no more different than a normal danio fish breed. They are productive, very dynamic, and quick swimmers. You can see your Danio fishes enjoying the strong current in the tank.

Habitat And Care
The Longfin Leopard Danios are more comfortable in a habitat that is similar to their native conditions. These species mostly prefer moving waters as they are habituated in the lower reaches of streams and canals in nature. You can set up a planted aquarium for your Leopard Danios so that they can get a feeling of their natural habitat.
As for the ideal water condition for the Leopard Danios, you must keep the water temperature between 70°F to 78°F. Adjust the pH level above 7.0 and below 7.8 and maintain alkalinity between 3° and 8° dKH (50 ppm to 140 ppm).
Note: Do not keep the water temperature too low, or the Leopard Danios tend to become quite vulnerable and susceptible to disease.
Diet And Feeding
The Leopard Danios are omnivorous. You can either feed them a meaty diet or plant matters. The species eat anything you feed them, so that may be a plus point for you!

How Long Can My Danios Go Without Food?
What about my fish? How long can my fish live without food? If you’re going on a vacation, you’ll probably have these questions over your head!
Well, almost any fish can normally live from 2 to 3 days (or even more than that) without fish food.

As for Longfin Leopard Danios, they can go for two weeks without eating. Quite a strong fish, right!

You must be very specific while choosing tanks for your fishes or fishes for your tank!
The Leopard Danios can grow approximately up to 2.4 inches, and they must be kept in groups of a minimum of five fishes. So, you’ll probably need a fish tank of at least 10-gallon for them.
Technically, the Leopard Danios are considered to be cold-water fish. However, these fishes need a temperature of around 70°F to 75°F, so you may need a heater to regulate the water temperature.
A good heater for Leopard Danios would be hygger 50W Mini Submersible Digital Display Aquarium Heater. It is quite flexible with temperature management and easy to operate.
Also, the danio fishes prefer moving waters. So, you might want to add a filter to replicate their riverine habitat.
As for the substrate, use a darker colored one like gravel or marbles. The dark substrate tends to absorb more light and keep your tank warmer. This will also help showcase the color of your Leopard Danios and give them a more natural feel.

Can Leopard Danios Live Without Filter?
The Longfin Leopard Danios are one of the few fishes which can survive without an aquarium filter. Aquarium filters are just an option to create a strong current for the Danios. This might be a reason why Leopard Danios are just perfect for those who are budget conscious.
Longfin Leopard Danios Availability
The Longfin Leopard Danios are widely so popular that they are readily available and inexpensive as well. You can find these species in the nearest aquarium stores, online, and even through mail order.
Leopard Danios are very easy to breed. Sometimes, breeding may even occur in an accident, and you won’t even know! Unlike other fishes, the male Longfin Leopard Danios stay faithful to one female. These fishes form a breeding pair that they often keep for life.
Like most fish species, the Leopard Danios also fertilize externally. The female danios release their eggs in open water, and then the males fertilize them. The eggs will sink to the bottom of the tank and falls through the substrate. The fish fry will rise out of the substrate after around seven days or so.
Though breeding the fishes may not be difficult, extra care is required to raise the fry to adults. There is a huge possibility that the parents can make a snack out of the fry.
Therefore, you must constantly feed the parents so they won’t devour the fry. You can even try removing the parents from the tank. This might increase the chances of fry to survive.

Longfin Leopard Danios Disease
The disease is not usually a problem for the Longfin Leopard Danios as these fishes are very less susceptible to any disease.
However, the fins may be extra sensitive to fin rot and other such diseases. If the fins develop enormous tears, you can add a fin repair medication as soon as possible.
Also, adding new fishes, plants, or substrates may increase the risk of introducing disease. You must properly clean, quarantine, or isolate the new additions to not disturb the balance of the fish tank.
