They are a delightful addition to any aquatic setup, as their presence can infuse the aquarium with a sense of harmony and balance.

Natural habitat

The home of Lemon Tetra is South America. inhabits the Brazilian rivers, which are Amazon tributaries. The fish, a species found in aquariums, gained popularity as early as 1932 and is now widely known because of its remarkable beauty, unusual appearance, and relatively carefree attitude. In the wild, lemon tetra prefers calm, quiet currents, flooded forests, and shallow lakes.

Characteristics of appearance

The species’ name accurately describes its appearance. The scales have a silvery sheen, and the predominant color is yellow. The shape of the body flattened slightly at the sides. Tetras are distinguished by their translucent bodies. The fish’s eyes, which sparkle brilliantly with a ruby hue when light is reflected in them, deserve special attention. An adult’s body length is no more than 5 cm. 4–8 years is the life cycle duration.

The fins’ weakly expressed color pigment only becomes visible when light strikes them, revealing a pale yellow hue that borders on transparency. Rays of black travel along the dorsal fin. The female is distinct from the male in that the black stripe that borders her anal fin at the bottom is precisely twice as short on the female than it is on the male.

A further characteristic that sets females apart is their wider bodies and lighter skin tones. When spawning starts, dark grains of eggs can be seen through the females’ translucent bodies in the swim bladder. This feature allows you to choose the most promising individuals for reproduction during the spawning period.

Features of care

Although lemon tetras are not particularly erratic fish, it is advised to keep the water quality high for their sake. In order to achieve this, an aquarium filter must be installed, and depending on how much dirt has managed to get in there over the course of the two weeks, the water must be replaced from 25% to 50% of its original volume every two weeks.

Weak lighting—the fish prefer deep shadows and dusk. Without fail, an aeration system needs to be installed.

Up to 40 liters is the ideal aquarium capacity for housing two adults.

The aquarium’s capacity must be increased if the lemon tetra has any neighbors. Essential water characteristics:

• temperature regime – from +22° to +28°C;
• pH level – from 5.5. to 8.0;
• hardness – from 3 to 25 dGH.

Sand can be used to cover the bottom, and the aquarium’s water flow should be minimal. Plants are required in the container; they should be positioned against the back wall and along the aquarium’s sides. These little fish require sturdy housing. For this, hollowed-out snags, pots, grottoes, and decorative castles are employed. Bog wood and roots will be very appealing to lemon tetras.

It is advised to toss a number of wet tree leaves into the water. By taking this action, the water’s color will become more brownish, coming closest to the fish’s natural habitat. Every two weeks, when the aquarium is being cleaned, the leaves should be replaced. Plants like Thai fern and Java moss work well as underlayment.

Feeding rules

The lemon tetra should have a proper, balanced, and constantly changing diet. Feeding the fish with both live and dry food is essential. Every member of this species has unique dietary requirements. It is easy to identify them; all you need to do is observe for a while how the fish responds to different kinds of food.

On the other hand, some people favor plant-based foods, while others favor foods high in protein. Dry foods made in factories that are designed especially for fish of this species and contain the vitamin and mineral complexes required for tetras’ complete growth and development are particularly well-liked.

The best course of action is to switch between dry food and natural goods, primarily meat. The fish’s color will become more vibrant and saturated if it contains an adequate amount of protein.

Reproduction and development

The fish is equally demanding of the conditions under which reproduction will occur as it is unpretentious to keep. Although it is rare, spawning in captivity is a possibility, so the aquarist will need to work hard to carry out the plan. Lemon titra females are prone to obesity, which renders them sterile.

It is advised to place a school of three or more male fish in the aquarium during the spawning season to maximize the likelihood of reproduction.

You will need a tank that can hold up to 10 liters for one pair. The female needs to be split from the male two to three days prior to the commencement of spawning. During this time, both should be fed frequently, primarily with animal-based foods that are high in protein. Aside from providing superior nutrition, the aquarium’s water needs to be changed. The goal of this is to mimic the natural habitat’s rainy season. The fish actively start to spawn at this time of year.

A spawning tank, designated specifically for fish spawning, is filled with a separator net, a washcloth, and tiny leafy plants. Distilled water must be combined with aquarium water; add a small amount of peat to the mixture to give it a yellowish tint. It is essential to follow the water parameters for successful spawning:

• degree of hardness – from 1.5 to 10;
• water temperature – from +25° to +27°C;
• acidity level – from 6.0. to 7.0.

Raising atmospheric pressure can encourage sprouting. The fish will need a few days to adjust to their new surroundings. Mating games will start as soon as a pair of lemon tetras has completely adapted. 200–300 eggs are laid by the female during a single spawning. It is necessary to remove the adults after spawning is complete. The water needs to be replaced in excess of 60%.

The incubation time is roughly thirty-six hours. The walls of the aquariums must be made darker while the fry are maturing; lighting should not be present. About 3.4 days after hatching, the fry will be able to feed themselves and swim around the aquarium. The yolk sac’s contents are what the young eat during their first few days of life. Afterwards, the fry are fed with the following:

• "live dust";
• cyclops eggs, brine shrimp;
• microworm.

You can start feeding them adult food a week after the fry hatch, but it needs to be chopped up small. After ten minutes, it is advised to use a net to remove any remaining food.

Character and compatibility with other aquarium species

The lemon tetra is a peaceful fish that isn’t very aggressive. This species’ representatives will make great neighbors for other undersea creatures. However, you shouldn’t mix aggressive fish and large species with lemon titra. The most desirable neighbors are:

• representatives of the characins: rhodostomus, tetras, neons, minors;
• laliuses;
• angelfish, apistograms;
• small catfish.

It is not advised to keep lemon tetra with members of the veil species because this may cause the fish’s fins to tear off. The aquarium should be very large if you want to combine these species so that the fish hardly overlap.

Since lemon tetras are shy creatures, the aquarium should have plenty of hiding spots for them. The fish move erratically in the water, occasionally stopping in one particular position. This species’ representatives only form larger groups when they sense danger or are under stress. They live in small schools.

Possible diseases

This species of aquarium fish prefers to live in the middle or lower water layers. A fish may not have enough oxygen in the water if the aquarist observes that the fish is rising to the surface more frequently and that its breathing is changing more frequently at the same time. Should this occur, the water must be replaced with at least half of its original volume. Connecting the filter more frequently and turning on aeration are also essential.

Due to their propensity for obesity, lemon tetras—especially the females—should never be overfed. After feeding, no food should remain in the aquarium; the fish should be taken out of it within five to ten minutes.

Every two weeks, you can set up a fasting day for your pets to help prevent obesity.

Furthermore, lemon tetras are vulnerable to fungus-related illnesses brought on by low water quality, disregard for regulations, and extreme pollution. Simple parasitic organisms may begin to grow on fish scales as a result of pollution. If all the requirements are met, the lemon tetra will be in good health and have a fairly high level of physical stamina.

With an average-sized aquarium, it is recommended to have up to 6 individuals, but if the volume allows, you can settle a larger number of these beautiful fish. The main thing is that there is enough free space for them. In cramped conditions, the fish will experience stress, their behavior will change, they will often get sick, become apathetic and lethargic.
2. Bright colors appear in those fish that live in aquariums with a sufficient amount of greenery. The peculiarity of the lemon tetra"s behavior is that it is calm about plants, does not try to dig them up or damage them, so you can not be afraid that densely planted thickets will be hopelessly spoiled.

The conditions that are closest to the lemon tetra’s natural habitat provide the most comfortable living environment. In order to replicate the comfortable backwaters of Brazil, where fish naturally reside, the aquarium’s bottom should be covered with sand, driftwood, and leaves, primarily oak or birch. It’s important to scald the leaves with boiling water beforehand to prevent the introduction of simple parasites.

Lemon tetras are lively, entertaining fish that have a good vertical leap, particularly when food is added to the aquarium. Because of this characteristic, the aquarium should always have a lid on it; otherwise, the agile fish runs the risk of falling overboard.

The lemon tetra is an unusually translucent fish with an adorable, nimble, and active body. These companions will turn into a vibrant aquarium decoration. This species can be identified by its peaceful, non-aggressive nature and ease of coexistence with other aquarium animals. The fish are robust and in good health when given the proper circumstances. They are easy to keep even by a novice aquarist, but some experience is needed for breeding.
