20 gallon Fish tank Review

20 gallon Fish tank Review | Types of most popular Fish tank

The 20 gallon fish tank (75.7 l) is the most popular choice for aquarium owners to start. Unfortunately, many people choose that is too big or small for the tank or fill it too much, and the fish get sick. To maintain a healthy environment in this type of tank, the owner must choose the fish carefully to make sure that they are compatible with the small tank size.

20 gallon Fish tank Review | Basic considerations:

When filling the tank, remember that the 20 gallon (75.7 l) tanks are very small. In general, if you are creating a community tank, you can keep one inch (2.5 cm) of fish per gallon of water (7.7 l). Keep in mind that this measure is based on the total length of mature fish, not on the length they have when you buy them. Balloonfish, for example, is not appropriate for a 20-gallon tank, because a small 1-inch (2.5 cm) puffer fish can grow to 10 inches in adulthood (25 cm). Also, some fish, such as head teas and light tails, are small, but they need a lot of space due to their level of activity, and they do not go well in a 20-gallon fish tank (75.7 l).


Three types of fish for your 20 gallon Fish tank:

Goldfish

Goldfish

The classic goldfish is perfect for those people with a basic aquarium or aquarium. The carpín is one of the simplest fish to maintain and has a long life expectancy, sometimes living more than ten years.

Normally they appear in orange with a slightly golden tone, hence their name in English; goldfish (golden fish). However, they can also be presented in combinations of silver, white, blue and black.

React well to oxygen so cleaning and replacing the filter and fish tank is important. Although multiple carpines can be placed together in a tank, it is recommended to allow only one to three fish when starting an aquarium. The carpín can be mixed with other types of fish. They can be fed regular food for their species in flakes although it is important not to feed them. Feeding them once or twice a day with the recommended portions is appropriate.

Molly Fish

Molly Fish

Molly is a tropical fish that blooms in aquariums of 20 gallons or larger. A small spoonful of salt should be added for every 5 gallons of water to allow Molly to develop.

They grow approximately two to four inches and come in black, orange and green. Their life expectancy is around three to five years.

The molly have a peaceful temperament. Molly are easy to care for which makes them good fish for first-time owners of an aquarium. It is recommended to have only one sex since they mate easily. These fish are not compatible with many varieties of fish, so you should be careful before adding other species to your aquarium. They can be fed regular food for flaked fish.

Neon Tetra

Neon Tetra

The neon tetra (Paracheirodon innesi) is tropical fish is popular in aquariums because it comes in a wide variety of metallic colors. The small, thin fish swims in fast patterns, grow as much as an inch and live to eight years. Perfect for more mature aquariums, tetra neon lives better in tanks in which the pH is well established.

Due to its small size, this is an ideal fish for aquariums with a tank of 10 gallons or less. Tetra neon lives well in a group environment with six or more of the same species. They are peaceful and get along well with other fish.

These fish feed on food in flakes for tropical fish. They battle in water with a high level of nitrate; therefore, it is essential to wash the tank often.

Get Attention for 20 gallon Fish tank:

An aquarium tank that looks clean and glistening could still be holding harmful waste. Fish produce ammonia, which is degraded by bacteria in the nitrogen tank in less harmful byproducts. Both ammonia and its derivatives are dangerous for fish in high concentrations. Selecting smaller fish that do not produce a large amount of waste is one of the keys to a healthy aquarium, such as avoiding overcrowding. A general rule is to allow one gallon of tank capacity to one inch of fish. And look for other types of fish, in addition to colored fish: they are popular, but produce a lot of waste.

A suitable variety is the tongue of the tiger, which is gold plated with black stripes and a reddish tint to its fins. Fish breeders have also created albino and green varieties. Tiger pits are grouped into schools that nip the fins of other fish in the tank. Cherry barbs are less aggressive. The males are dark red, while the females are reddish-yellow. Six tiger quills or 10 cherry picks could live in a 20 gallon tank.
