Tetras fish species Personality, Habitat, Care and Diet

tetras fish

Tetras are members of the Characidae family and its former subfamilies Alestidae and Lebiasinidae. They are native to Africa, Central America, and South America.

Tetras are usually very peaceful, and people buy them for their calm and hardiness. They can be kept by both beginner and experienced aquarists with perfect results.

Tetra is no longer a phylogenetic or taxonomic word. It’s short for Tetragonopterus, a genus name for several of these fish that means “square-finned” in Greek.

Tetras Personality

The majority of tetras is calm and get along well with other social fish of similar size, however there are a few exceptions. Serpae tetras, for example, can be aggressive at times, especially if maintained in small numbers.

They’re calm, beautiful fish with a lot of color and personality packed into little bodies.

Tank Setup

Tetra fish are freshwater fish, so you’ll need to keep them in an aquarium with similar conditions. The temperature should be kept between 68 and 78 degrees Fahrenheit, and the PH should be between 5.5 and 7.5, giving in soft to medium water hardness.

They should only be kept in a community tank with other non-aggressive fish that aren’t big enough to eat them because they are such little fish. They are ideal tank mates since they are little, calm bottom dwellers.

Here are some things to keep in your mind when setting up a tetra fish tank.

  • Wash aquarium gravel, rocks, and ornaments thoroughly in warm water before placing them in your tank.
  • Soap and detergents are very harmful to fish, so don’t use them.
  • Keep live plants wet until they’re ready to be planted.
  • Fill your tank all the way to the top frame bottom, allowing some room between the water and the lid.
  • Make sure water is flowing properly through your power filter.
  • Check the air outlet and adjust the settings.

Tankmates

Tetra fish get along well with a wide variety of other fish, but they’re especially good with calm fish in your tank. Rasboras, guppies, mollies, danios, betta fish, gouramis, and angelfish are just a few of the neon tetra species that get along well.

Tetras like to live in schools and can become disturbed if left alone, according to studies. Interestingly, despite their dislike of loneliness, tetra never forms a close pack in a tank unless a threat is present.

Tetras of the same species tend to school together and can only thrive if there are enough members in a school. It’s not a difficult task. It’s simple.

 Tetras fish Habitat and Care

Tetras are easy to keep and may be kept with basically any other non-aggressive species. These fish have vibrant colours, energetic personalities, and are less sensitive to water conditions than other fish. They grow to a maximum size of 2″ and can live in captivity for up to 10 years if properly cared for.

Tetra Fish Diet and Feeding

Tetras are omnivorous, so Aqueon Tropical Flakes, Color Flakes, Tropical Granules, and Shrimp Pellets are ideal for them. Frozen and live foods can be used as treats or to aid in the spawning process. Rotate their meals on a regular basis for optimum results, and only give them once or twice a day what they can take in under 2 minutes.

FAQ, Tetra Fish

Q. How long do tetras live for?

A. The Tetras are said to live for 10 years on average. Because they are sensitive to direct light rays, Paracheirodon innesi prefers blackwater environments. In an aquarium, you should keep 6-12 Tetras together. They are most active in a group of 12 or more.

Q. What is the maximum number of tetras that should be kept together? 

A. In one tank, at least six neon tetras should be maintained together. Because neon tetras are a schooling species, you should keep at least six to ten of them in one tank. If you keep too few neon tetras together, they will become uneasy, agitated, and even die.

Q. What kind of fish can get along with tetras?

A. Others, such as Buenos Aires tetras, can grow to be extremely huge and energetic, which might be intimidating to smaller, more timid fish. Other tetra species, rasboras, tiny danios, tranquil barbs, properly sized rainbowfish, and livebearers are all good tank mates for tetras.
