Gender Differences
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.

Tank Setup
You must be very specific while choosing tanks for your fishes or fishes for your tank!
Tank Size
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.
Water Temperature
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.
Filter
Also, the danio fishes prefer moving waters. So, you might want to add a filter to replicate their riverine habitat.
Substrate
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 why Leopard Danios are just perfect for budget-conscious people.
Longfin Leopard Danios Availability
The Longfin Leopard Danios are widely so popular that they are readily available and inexpensive. You can find these species in the nearest aquarium stores, online, and even through mail order.
Breeding
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. First, 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.
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 surviving.

Longfin Leopard Danios Disease
The disease is not usually a problem for the Longfin Leopard Danios as these fishes are less susceptible to any disease.
However, the fins may be sensitive to fin rot and other 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 disease risk. Therefore, you must properly clean, quarantine, or isolate the new additions so as not to disturb the balance of the fish tank.
