Description

The fish known as glowfish is a genetically modified Danio rerio. In the wild, rerio can be found in freshwater rivers in Bangladesh, Pakistan, and India.

Chinese scientists were the first to breed genetically altered fish after they extracted the glow gene from jellyfish and successfully inserted it into the danio rerio embryo. The first fish that glowed were green.

After that, the danio underwent more mutations, which caused the fish to diversify and acquire new colors in addition to expanding well beyond its original range. The glofish modification was also applied to other fish, such as tetra.

Glofish are small fish that typically measure no more than 5 cm. Their bodies are flexible and have a slight side flattening. Compared to adult fish, juvenile fish have substantially shorter fins.

Their plumage develops into a lovely veil with a yellowish border as they get older. In the corners of the mouth, there are two sets of whiskers.

Glofish: what makes the fish glow

These fish are called glow fish in English, which means "shine" and fish in English.

Danio glows because their DNA contains the genes of two jellyfish species: discosoma, or red coral, which glows red, and aequorela victoria, which gives off a green glow.

A yellow glow is caused by inclusions in the genes of both coral and jellyfish.

Differences from other breeds

The following are some ways that genetically modified dainos differ from other breeds:

  1. Longer lifespan (up to 3.5 years).
  2. Glofish is noticeably larger than other danios. A regular fish rarely exceeds 3 cm, and glofish reaches 5 cm in length.
  3. They require higher water temperatures – within 27…29 °C.
  4. A wide variety of colors. Stripes on their body of silver color, while the rest of Danio are blue and golden.

Varieties

Originally, the three primary color options were green, red, and yellow. However, new varieties were obtained by selecting fish that had already undergone modifications.

  • fiery red star;
  • electrically green;
  • cosmically blue;
  • lilac galaxy;
  • sunrise of the pink moon;
  • Sunny orange.

Care and content

Danio Glofish are an unassuming group of fish that share nothing in common with regular Danio fish except for their neon colors, even though their DNA has changed.

Requirements for the aquarium

Because danios can be frightened and jump out of their tanks, choose a tank with a lid.

In order to avoid restricting the movement of these agile and energetic fish, it is recommended to use an oblong aquarium. Additionally, blue lighting must be installed in the pond.

When organizing the bottom, select soil that is free of sharp edges and inclusions. The best option is to use small pebbles or large sand that has been uniformly painted.

To keep the center of the aquarium empty, plants are placed closer to the side walls and along the edges.

Water requirements

Since glofish are freshwater fish, the same criteria apply to danio. Water that is neutral or alkaline, with a pH of 6 to 8, and moderate hardness will work well for them.

Crucial! The essential microelements (potassium, sodium, and phosphorus) must be present in the reservoir.

It is recommended that the water temperature not be allowed to drop below 22 °C or rise above 28 °C. Furthermore, an aerator is connected to ensure that the water contains an adequate amount of oxygen.

The aquarium’s volume is determined using the formula below: Five liters for each person. Thus, it is preferable to use a reservoir with a small reserve for a school.

Feeding

Once in the morning, feed the danio. Keep in mind that food that falls to the bottom will not be consumed, so adjust the portion sizes based on how hungry the pets are.

For tropical fish, any option in the form of flakes is appropriate. You can include daphnia, bloodworms, tiny crustaceans, and plant seeds in your diet. A 1:5 ratio of fresh food to dry food is added.

Common diseases

Major disease resistance is exhibited by Danio. Diseases most frequently arise from noncompliance with the maintenance schedule.

The most prevalent illnesses:

  • mycobacteriosis;
  • intestinal capillariasis;
  • velvet disease.

Indices of illness:

  • loss of color brightness;
  • exophthalmos;
  • spots or plaque appear on the body;
  • the fish loses balance;
  • defects in the structure of the fins or tail appear;
  • the eyes become cloudy.

Sick people should be moved into a different container as soon as the illness shows symptoms and should remain there until they recover.

Melanene Blue, table salt, "Erythromycin," and "Trichopolum" are used as treatments.

Life expectancy

Glofish have slightly longer lifespans than their natural counterparts. They have a 3-3.5 year life expectancy, and they can live up to 5 years if they receive proper care and follow a diet.

Compatibility

A suitable partner for Glofish would be:

Aggressive neighbors shouldn’t be placed next to glofish:

Purchase

Although you can purchase fish online, it is still preferable to purchase fish from pet stores where you can examine each animal’s health firsthand.

Since glofish are schooling fish, they typically eat three or six people at once. They can cost up to three thousand rubles per school, which is a significant amount.

Consider the consistency and intensity of color when selecting fish. Absence of spots or other skin abnormalities, which could point to the onset of a disease).

There should be two whiskers on each corner of the mouth and no mechanical damage to the plumage. The fish are curious, lively, and in good health.
