How to Breed Neon Emperor Fish

The Neon Emperor is not a difficult fish to keep, you should set up your own aquarium if you want to keep a large number of fry. The aquatic environment should be dimly lit and have clumps of leafy plants such as java moss or reeds for the fish to spawn.

First, when you buy fish, you have to drop the whole bag into the water tank for a short time. This action helps the fish to acclimatize to the aquatic environment. When the fish is healthy, it is best not to add new disease-susceptible fish. You should also prevent fish disease by adding methylene blue to the water. It is recommended to maintain an aquatic environment with a temperature of about 20-26 degrees Celsius, a pH of 5-7.

As a fish that lives in dark waters, Neon Kings will not work in brightly lit tanks. Let the light dim and add a dark background, along with a few small pieces of driftwood and twigs to recreate their natural habitat. You can also add a few dried leaves for a natural yellow color from the tannins, but the leaves should be changed every few weeks.

The South American watershed where the main distribution of neon fish is found doesn’t have much vegetation, so you don’t need to plant a lot of aquatic plants in your aquarium. Instead, you need to provide enough open space for the fish to swim freely, if the environment is ideal, the Neon King will swim very quickly and dynamically.

In the wild, neon king fish are omnivorous, so you can feed them small crustaceans, worms, etc. But in the aquarium they can eat dry food or fresh food. When feeding fish, you should only feed them moderately, you can feed the fish 2 times a day. Neon fish should not be overfed and excess food will contaminate the tank water causing illness and death.
