As an expert in the field, he finds great pleasure in imparting his extensive knowledge and personal experiences to both seasoned aficionados and budding enthusiasts.

Many aquarists love tetras for their peaceful nature, and how easily they can adjust to different kinds of setups.

Tetra species inhabit a range of habitats, from South America to East Africa, where they are sourced from wetlands, lakes, ponds, and rivers.

Most of the tetras will thrive in moderately warm tanks with strong water currents. The most popular tetra fish include:

1. Cardinal Tetra (Paracheirodon Axelrodi)

• Adult Size: 2 inches (5 cm)
• Minimum Tank Size: 20 Gallon
• Water Temperature: 73 – 80 °F (23-27 °C)
• Temperament: Peaceful
• Lifespan: 2-4 Years

The cardinal tetra closely resembles the more popular neon tetra. It is indigenous to the South American countries of Venezuela, Brazil, and Colombia in environments like the Rio Negro tributary.

In the wild, the cardinal tetra prefers waterways covered by dense rainforests where the water is either static or slow-moving.

It is a schooling fish, and you should, therefore, keep a community of fish in your tank.

The temperature should range between 73 to 80 °F with a PH of below 6. Ensure that your tank has an open swimming space in addition to several hiding places.

You can opt to have a planted aquarium with an open central region.

Being omnivorous, the cardinal tetra will eat most foods, but you should provide a lot of flake foods to satisfy their vitamin requirements.

The fish will generally be easy to keep since they are rarely vulnerable to diseases. Ensure that the chemistry is stable at all times.

The cardinal tetra will co-exist peacefully with other species including the other tetra species, dwarf gouramis, and danios.

2. Congo Tetra (Phenacogrammus Interruptus)

• Adult Size: 3 inches (7.5 cm)
• Minimum Tank Size: 30 Gallon
• Water Temperature: 74 – 82 °F (23-28 °C)
• Temperament: Generally Peaceful
• Lifespan: 3-5 Years

The Congo tetra is recognized for its radiant appearance, and it is sourced from the Congo River. Its body has green, blue, red, and yellow hues, and its scales are characteristically large.

It is one of the larger tetras, as it can reach lengths of three inches.

Breeding the Congo tetras had mixed results after it was first discovered, but aquarists in Florida successfully reported a breeding line in the 1970s.

In its natural habitat, the Congo tetra favors slightly acidic water and tall vegetation as well as substrates consisting of mud, sand, and silt.

The Congo tetra will, therefore, thrive in dark and still water with low light.

You can achieve this setting by coupling floating plants with dim aquarium lights. Invest in a 40-gallon tank or larger to give the Congo tetra enough space to roam.

The temperature requirements for the Congo tetra is between 74 to 82 °F while the PH should ideally fall between 6.0 to 6.5.

Ensure you keep at least six of the species together, and it is best to avoid aggressive tankmates that may bully the Congo tetra.

3. Bleeding Heart Tetra (Hyphessobrycon Erythrostigma)

• Adult Size: 2.5 inches (6.5 cm)
• Minimum Tank Size: 20 Gallon
• Water Temperature: 72 – 80 °F (22-27 °C)
• Temperament: Peaceful
• Lifespan: 3-5 Years

The Bleeding Heart Tetra is quite hardy, making it a favorite among beginning aquarists. It is notable for the red spot on their sides, which have earned them the name Red-Tipped tetra.

It is sourced from the Amazon River Basin, as well as other river basins in South America.

You will need a 20-gallon tank at minimum to keep the Bleeding Heart Tetra. The temperature should fall between 72 to 80 °F with the PH between 6.5 to 7.0.

The tetra will generally occupy the middle and bottom areas of the tank, and it will only swim to the top if oxygen is not sufficient.

Since it is a schooling fish, it is best to keep the Bleeding Heart Tetra in schools of four to six species. Other tetra fish will make good tankmates as will Rasboras and Danios.

4. Red Eye Tetra (Moenkhausia Sanctaefilomenae)

• Adult Size: 2.8 inches (7 cm)
• Minimum Tank Size: 30 Gallon
• Water Temperature: 72 – 80 °F (22-27 °C)
• Temperament: Peaceful
• Lifespan: 3-5 Years

The Red Eye tetra is noted for the bright red spot near its eyes, and the silvery-golden hue on its body.

The yellow band present at the base of the tail fin has earned it the name Yellow-banded Moenkhausia.

It was first described in 1907, and it inhabits the rivers of western Brazil, eastern Peru, Paraguay, and eastern Bolivia.

It will generally reach a length of 2.75 inches, with a lifespan of three to five years. It will especially appeal to beginners because it tolerates different water conditions.

The temperature can range between 73 to 82 °F with a PH of between 5.5 to 8.5.

The Red Eye Tetra is known to be peaceful, and it will thrive in a community tank. Since they inhabit areas with dense forests in the wild, you should maintain a dimly-lit tank.

Use plant cover and a dark substrate on the aquarium’s sides and back.

5. Neon Tetras (Paracheirodon Innesi)

• Adult Size: 1.4 inches (3.5 cm)
• Minimum Tank Size: 10 Gallon
• Water Temperature: 69 – 80 °F (21-27 °C)
• Temperament: Peaceful
• Lifespan: 8-10 Years

Neon tetras are very popular in the fish-rearing community, thanks to their ease-of-care and attractive colors. It was discovered in the Amazon in 1934. Its appearance includes a blue line that extends from its eyes to the adipose fin.

Another red line stretches from the center of their body to the caudal fin. The rest of the body is transparent, and they can even hide the blue/red sheen to stay safe if they feel threatened. The average size is 1.5 inches, and they will need a minimum tank size of 10 gallons.

In the wild, the neon tetra prefers dense canopies, which is why you should keep them in a heavily planted tank. Driftwood will provide more darkness and shade.

The water’s PH should fall between 6.0 to 7.0 with temperatures between 70 to 81 °F.

It is easy to feed neon tetras as they will welcome frozen and live foods as well as flakes and pellets. The fish will thrive in a community of peaceful bottom dwellers like dwarf cichlids, small catfish, and gouramis.

Avoid keeping neon tetras with nocturnal aggressive fish, because they might eat them.

6. Black Phantom Tetra (Megalamphodus Megalopterus)

• Adult Size: 1.4 inches (3.5 cm)
• Minimum Tank Size: 15-20 Gallon
• Water Temperature: 72 – 82 °F (22-28 °C)
• Temperament: Semi-Aggressive
• Lifespan: 5-6 Years

The Black Phantom Tetra is a native species of central Brazil and Paraguay. It is recognized for its black translucent appearance, and you can make stunning contrasting displays if you couple it with red-hued tetra species like the Serpae tetras or the Red-Phantom tetra.

The Black Phantom Tetras will be at home in a well-planted tank, dim lighting, and a dark substrate. Keep them in around 20 gallons, and close the tank as they are noted jumpers.

The temperatures and PH should be 72-82 °F and 6.0-7.5, respectively.

One interesting aspect with Black Phantom Tetras is the “mock fights” that involve the males. They mainly quarrel over territorial space, although the battles result in minor injuries.

7. Buenos Aires Tetra (Hyphessobrycon Anisitsi)

• Adult Size: 2.8 inches (7 cm)
• Minimum Tank Size: 20 Gallon
• Water Temperature: 72 – 80 °F (23-27 °C)
• Temperament: Aggressive
• Lifespan: 5-6 Years

The striking beauty of the Buenos Aires Tetra will spruce up any aquarium. It has a silver body with an olive and brown back.

Its abdominal, anal, and dorsal fins can be yellowish or reddish. The Buenos Aires Tetra was described in 1907 after being discovered in South America.

It will be easy to care for, but it has been known to nip the fins of other fish or crop tank plants. Keep them in schools of seven to tame their aggression.

Its average size is 2.8 inches with a lifespan of up to five years. If you intend to keep a community tank, keep the Buenos Aires Tetra with fast and similarly-sized tankmates.

8. Glowlight Tetra (Hemigrammus Erythrozonus)

• Adult Size: 2 inches (5 cm)
• Minimum Tank Size: 10-15 Gallon
• Water Temperature: 72 – 80 °F (22-27 °C)
• Temperament: Peaceful
• Lifespan: 3-4 Years

The Glowlight Tetra is among the smaller tetra species with a maximum size of two inches. It has a semi-transparent body with an orange-red line across its length. Keep a tank-size of 15 gallons or more to fit six to seven fish species.

To make the lights soft and dim, add several fluctuants in the tank. Glowlight tetras are quite sensitive when it comes to water parameters. There should be low concentrations of nitrates and ammonia and a PH of between 6.0 to 7.5.

The fish is compatible with varieties of similar size. You can couple it with most of live-bearing fish and other tetra species. Refrain from pairing them with larger species like the cichlids.

9. Lemon Tetra (Hyphessobrycon Pulchripinnis)

• Adult Size: 2 inches (5 cm)
• Minimum Tank Size: 10 Gallon
• Water Temperature: 70 – 82 °F (22-28 °C)
• Temperament: Peaceful
• Lifespan: 4-5 Years

The Lemon tetra is another of the tetra species native to South America. It is easily noticeable by its bright yellow markings. There is a red color on the upper region of the eyes.

To mimic the natural habitat of the Lemon Tetra, keep them in a densely-populated tank.

Leave a large and open area for the fish to swim, as they like to roam across the top and middle parts of an aquarium.

Acidic water is recommended for Lemon Tetras, although they will adjust to levels of between 5.5 to 8.0.

Keep the temperatures between 70 to 82 °F. A varied diet is ideal for Lemon Tetras, and you can supplement flakes with boiled vegetables.

10. Penguin Tetra (Thayeria Boehlkei)

• Adult Size: 1.2 inches (3 cm)
• Minimum Tank Size: 10 Gallon
• Water Temperature: 72 – 82 °F (22-28 °C)
• Temperament: Peaceful
• Lifespan: 5-8 Years

The Penguin Tetra resides in the upper Amazon River Basin. It prefers small streams, from where it targets crustaceans, insects, and worms for food. The aquarium size is between 20 to 30 gallons, and you can keep about five of them.

The Penguin Tetra is especially sensitive to nitrates which is why you need to maintain high water quality. The PH range is between 6-8 with the temperature between 72 to 82ºF.

11. Blind Cave Mexican Tetra (Astyanax Mexicanus)

• Adult Size: 3 inches (7.5 cm)
• Minimum Tank Size: 20 Gallon
• Water Temperature: 68 – 77 °F (20-25 °C)
• Temperament: Peaceful
• Lifespan: 3-5 Years

The Blind Cave Mexican Tetra is quite unique, and it comes in two forms. One variety is eyed, while another has no eyes.

This variation is attributed to the environment they inhabit. The eyed community lives in brightly-lit waters while their eyeless cousins reside in dark caves.

The limited sun exposure in the eyeless fish also resulted in a pink-white coloration that resembles albinism.

When you first add the Blind Cave Mexican Tetra in your tank, they can be a bit shy and seek out caves around them.

They need a few weeks to memorize the way around your tank. Since they will be reasonably slow to feed, keep them with non-aggressive tankmates.

12. Diamond Tetra (Moenkhausia Pittieri)

• Adult Size: 2.5 inches (6 cm)
• Minimum Tank Size: 30 Gallon
• Water Temperature: 74 – 82 °F (23-28 °C)
• Temperament: Peaceful
• Lifespan: 3-5 Years

The Diamond Tetra is famed for its striking appearance. Its body is characterized by silver-gray scales with orange, gold, and green hues. The scales appear to shimmer when it is in motion, hence the name Diamond Tetra. The colors are, however, only pronounced in adults.

The Diamond Tetra originates in Venezuela, where it is a resident of the Guacara and Aragua rivers and Lake Valencia. It prefers thickly-planted regions, so it is best to have a tank with a densely-planted perimeter. Add floating plants, dark substrates, and dim lights. It prefers temperatures between 74 to 82 °F and a PH of 6.0 to 7.5.

13. Ember Tetra (Hyphessobrycon Amandae)

• Minimum Tank Size: 10 Gallon
• Water Temperature: 68 – 82 °F (20-28 °C)
• Temperament: Peaceful
• Lifespan: 2-4 Years

The Ember Tetra is sometimes called the Fire Tetra, and it inhabits rivers in Central Brazil. They have a fiery appearance which is an attractive attribute to aquarists.

They are playful and active in a tank, and you should provide plants for them to hide or swim through. The water temperature should be between 68 to 82 °F with a PH of between 5.5 to 7.0.

Use a silent filtration system and ensure that the water has no strong currents to avoid disturbing the Ember Tetra.

14. Emperor Tetra (Nematobrycon Palmeri)
