Lemon Tetras in Planted Tank

 

The fish prefers to live in quiet waters that are clear and clean with moderate current in the wild. In the wild the fish is known to inhabit in shallow waters near the banks of streams or rivers near the shores. The fish likes heavily vegetated areas on narrow portions of the stream where they cannot be hit by direct sunlight. This is why when introducing the fish in an aquarium setting, it is best to mimic what they live in the wild as much as possible.

Lifespan of Lemon Tetra

An ordinary healthy lemon tetra can live anywhere from 4-8 years. However, there isn’t a strict say in this. Some people have reported that their lemon tetras have exceeded the expected frame of life expectancy.

However, most of them live up to 6 six years in an artificial setting. The life of a lemon tetra depends on its mental state and surrounding environment.

Feeding Lemon Tetra

Basically, the lemon tetra is an omnivorous fish that feeds on other tiny animals in the wild. Some of the popular food that it eats in the wild includes; crustaceans, invertebrates, and other plant matter. This fish is so easy to feed because in captivity it will readily feed on anything it is offered. That said, you can easily feed them live or frozen fish food, high quality prepared fish food and live worms as well.

You have to feed your small Lemon Tetras twice to thrice (on average) in a day. However, if your fish is sick, you can cut the frequency to once a day.

Care For Lemon Tetras

The best part about having lemon tetras is their adaptability to a broader range of environmental conditions.

Lemon Tetra Tank Landscape

Do you know tank decoration can affect the mental state and body color of your lemon tetra?

Studies say that the lemony tint on tetras can appear to fade away and instead look ashy grey if they are stressed or anxious. Thus, along with keeping them in schools, it is essential to keep the tank environment as natural as possible.

Lemon Tetra Tank Landscape

Since Lemon tetras are freshwater fishes, the pond is highly lushed with greens and live plants. So, to mimic the environment and give a ‘Brazilian-Amazon’ touch, you can add live plants like Anubias.

For a wild biotope, lay a fine layer of sand on the base. As you move upward, you can add driftwood or roots.

You can also add floating plants, taller stem plants for a natural touch. However, make sure that there is ample space to swim through the green for the fishes.

Tank Setup for Lemon Tetra

Lemon Tetra is certainly one of the easiest freshwater fishes to keep in a home aquarium and care for. It doesn’t need much attention from the aquarist so long as all the basic care details for aquarium fish are observed. Because the fish shoal in large number when in the wild, it is best to keep them in groups while in the tank. Ensure that the aquarium water you are going to keep the fish in is soft. The fish is a community fish who will live with other small species of fish although it is best to keep only the fish species in the same tank.

Tank requirement

To help keep you in the loop about how best to keep and care for this freshwater aquarium fish, here are some tank requirements for you to follow:

  • These fish are a shoaling species and therefore you will need to keep at least a dozen of them in a tank which should be about 29 gallons.
  • The tank needs to be heavily planted just like the areas they like to inhabit while in the wild. Even as you keep the tank heavily planted, ensure that you leave some open spaces for the fish to use for swimming. Please note that when the fish are kept in tanks that are open, they tend to lose their coloring.
  • As you choose the best filter to you use in a tank for this fish, please use a hang-on-back filter that will essentially help to add some little-bit of current in the tank. Related Review: Best HOB (Hang On Back) Filter
  • The aquarium LED lighting should be moderate as strong lighting tends to make the fish appear as if they are all washed out.
  • The temperature in the water should be between 72° – 78°F (14 to 25°C).
  • The pH range of the tank water should be around 5.5 to 8.0.
  • As for the water hardness of the tank water should be 3 – 20dGH and should not be above this range because the fish has a tendency to lose its color in waters with higher dGH.
  • Avoid keeping the fish in brackish water.
  • The motion of the water in the aquarium should be moderate.

Lemon Tetras Behavior And Temperament

Lemon tetras are a fun-loving species of fish. They have a lot of fun swimming around and are also reasonably lively. Lemon tetras thrive in groups, and when left alone, they might become agitated.

In the open habitat, lemon tetra congregates in big groups known as shoals, containing tens of thousands of fish! Similarly, during the day, pet lemon tetra form groups and tour the tank together.

Lemon tetras are fantastic additions to community aquariums since they are not combative and are easy-going. They generally keep the peace, yet the males occasionally display minor violence toward one another when courting females. 

A few minor fights result from the slight hostility, but they rarely result in significant injuries. Larger fish intimidate them, yet they thrive on invertebrates like shrimp and snails.

Lemon Tetras Tank Mates

Lemon tetras get together with a wide range of tank mates, making them an excellent choice for community tanks. You must, however, maintain the peace.

Breeding Lemon Tetra

Breeding Lemon Tetra

Breeding adult Lemon Tetra is easy but attempting to breed its juvenile can be quite an uphill task for you. Fortunately, identifying adult of the fish is quite easy as the adult males and females are easy to distinguish just by a look at their anal fins. That of the male is usually wider and even becomes bigger when time for breeding is ready. You can condition the fish to get ready for breeding by feeding them live foods. This usually helps to hasten their breeding and then you can separate the conditioned fish (both the male and female) in different tank. This will help to avoid the possibility of the other fish from feeding in the eggs laid by the female.

Breeding Level – Easy/Intermediate/Hard 

The ease of breeding a lemon tetra is moderate. They can breed either quickly or with some reluctance depending upon the type of tank mates they have.

Lemon Tetra: Common Diseases and their Treatment

Diseases that affect other aquarium fish can still affect lemon tetras. The caretaker must be able to safeguard their pet fish against bacterial and parasite illnesses. All of this puts the fish’s health, as well as its survival, in jeopardy.

Another disease to be careful of is ich. Itchy white patches on the fish’s body cause it to scratch its sides against rough surfaces, indicating the disease.

The good news is that the owner can significantly reduce the occurrence of these horrible ailments. Because most infections are spread by contaminated water, we recommend replacing the water in your tank regularly.

Replace the water every other week regularly. To reduce the growth of dangerous compounds (such as ammonium) that are beginning to thrive in the fish’s habitat, you should take 20 to 50 percent of the volume.
