Introduction to the articles
The freshwater aquarium is the most popular aquarium in the world of fishkeeping. Their versatility and hardiness compared to marine aquaria have made them popular since the 20th century. Many tropical fish live in these aquaria, therefore making them popular to the hobby. The other four freshwater fish we're looking at, in detail, the livebearers, barbs, angelfish and tetras.
LIVEBEARERS
About the livebearers
The Poecillidae are a diverse group of freshwater fish mostly native to the Americas and Africa. There are three subfamlies to the Poecillidae and these fish from the family are known as 'livebearers'. Fish from the family include guppies and Endler's livebearer, swordtails, platies, mollies and lampeyes. These fish are named due to the fact that they give birth to live fry.
How to build a livebearer tank
The build will depend on which species of livebearer you are keeping. If you are building a tank for guppies and Endler's livebearers, you will need a gravel or aquasoil for the substrate and some plants i.e. guppy grass for shelter. Pour a decent amount of the substrate in the tank (10-20 gallons) and decorate the tank using hardscape (rocks or driftwood). For the other livebearers, it it similar but with a few differences. You will need a larger tank for swordtails and common mollies because they get fairly large in size. Fill the tank and let it cycle. Put the fish you want in the tank.
Livebearer care
Care depends on the livebearer you are keeping. Most livebearers do best between 74° and 78° F and pH between 7.0 and 8.4. The ratio of males-females for livebearers should be 1:3. Livebearers are omnivores, meaning they eat both meat and plant matter. Mollies are more herbivorous, so a little extra spirulina or other vegetable matter in their diet will result in better growth and colour. Guppies and Endler's livebearers, on the other hand, are more carnivorous. Since many types of livebearers are native to coastal brackish environments some experts recommend adding a tablespoon of non-iodized aquarium salt per 5 gallons of water, and even more for mollies. Others feel that minerals like calcium and magnesium that make water "hard" are key to keeping their livebearers healthy. Before adding salt or any other additive to your aquarium, make sure the other tank inhabitants will tolerate it. Do a 25% water change to keep them healthy.

A recap of the article:
BARBS
About the barbs
Barbs belong in the Cyprinid family, the same family where the danionins and goldfish are in. These pretty fish are a schooling fish, in groups of 10 or more to reduce aggression. Barbs are popular to the aquarium hobby because of their schooling behaviour and colourful bodies. There are 28 genera that has the common name 'barb' in it. Some are aggressive (tiger barb) while others are peaceful (cherry and golden barb).
How to build a barb tank
You will need the correct substrate, plants and hardscape for this build. Put some dark gravel, aquasoil or sand in first, then the hardscape then finally the plants. You may want plants that are native to their range to help them call the tank home. Pour in some of the substrate on the tank, then spread it. Put some large rocks or driftwood for the decoration of the build. Place some plants in the substrate. You may need root tabs for this if you have gravel. Fill the tank and let it cycle. Put some compatible barbs in the tank.
Barb care
While many barbs are found in soft, acidic water in the wild, the majority of aquarium species sold today are raised commercially in water that often has a higher pH and alkalinity than their native environments. The pH should be between 6.8 and 7.8, alkalinity between 3° and 8° dkH (50 ppm to 140 ppm) and temperature between 75° and 80° F. Clean 10-25% of their water every week or few weeks. Smaller species can be kept in 20 gallon aquaria, while tiger and rosy barbs can be kept in a 30 gallon, the redline torpedo barb can be kept in a 60 gallon tank. Barbs need to be schools of 10 or more and require a lot of swimming space. Barbs are omnivores, so feed them some frozen or live foods as an occasional treat.
Tiger barb- nice or mean?
The tiger barb (Puntigrus tetrazona) is one of the aquarium hobby's most popular species of barb worldwide. However these fish can be fin nippers if you put them with incompatible tank mates with long, flowing fins. They also nip each other's fins if there is a lack of food. The fish are known that because of their temperament. To prevent this from happening, it's best to do a species-only aquarium with this fish. The tiger barb was also used to be sold as GloFish, genetically modified fish.

ANGELFISH
About angelfish
Angelfish are some of the most popular cichlids originating from South America sold in aquarium shops around the world. They are hardy and unique for being tall instead of being wide due to their long, flowing fins. The angelfish are known to be peaceful at times, but one species is aggressive and that species is Pterophyllum leopoldi. Angelfish are great for cichlid lovers and experienced aquarists. If you want to own an angelfish or a school of them, read this care guide.
How to build an angelfish tank
If you want to keep angels in a species only aquarium, you will need a massive, tall tank (40-55 gallons) for the build. You will need a gravel substrate, hardscape and compatible plants. The driftwood should be horizontal or vertical to simulate fallen trees. Some floating plants should be added for shaded areas. Broadleaf plants such as Amazon sword are required in an angelfish tank. Fill the tank and let it cycle. Put the angelfish in the tank.
Angelfish care guide
Angelfish accept a wide range of water conditions, although they prefer slightly warmer water. The pH should be between 6.8 and 7.8, with hardness between 3° and 8° dKH (54 to 145 ppm). Temperature is best kept between 78° and 84° F. Maintain good filtration and perform water changes of 10% weekly or 25% every other week. Angelfish can be kept with discus if the temperature is above 82° F. While angelfish are generally peaceful fish, they are cichlids and can be aggressive toward one another, especially when attempting to pair off and spawn. Also, they will not hesitate to eat smaller fish. This does not mean they are aggressive, as many aquarists believe. Like most fish they are opportunistic and will eat anything that fits into their mouth.

TETRAS
About the tetras
Tetras are popular aquarium fish native to the Americas and Africa from the Characiformes order. There are 3 main families of tetras: Alestiidae, Characidae and Lebiasinidae. Many tetras are blackwater fish, meaning they live in tannin-stained water environments. Tetras are relatively easy to look after in the home aquarium. Many are peaceful community fish, but some are aggressive or semi-aggressive, so pick your tetra carefully. There are even blind tetras living in caves such as Astyanax mexicanus. We will dive into more detail of this species. The most popular tetras in the aquarium hobby include cardinal tetras, neon tetras, emperor tetras and ember tetras. All of these tetras are popular because of their bright colours and hardiness for the aquarium.
Mexican/blind cave tetra
One unique member of the Characidae family is Astyanax mexicanus, the Mexican tetra. It is native to the Nearctic realm which includes the lower Rio Grande and the Nueceses and Pecos Rivers in Texas, as well as central-east Mexico. The blind cave form is the best known variant of the Mexican tetra. Depending on the exact population, cave forms can have degenerated sight or have total loss of sight and even their eyes due to down-regulation of the protein αA-crystallin and consequent lens cell death. The fish in the Pachón caves have lost their eyes completely whilst the fish from the Micos cave only have limited sight. They grow up to 12cm in length. The non-cave version is grey with a black stripe near the tail and red fins. The natural habitat of this species are dark caves that are very rocky. There are many underground caves available that facilitate providing the ideal atmosphere for this blind species. Along with being blind, they have developed pigmentation issues in the skin cells and clear fins. Most of the fish do not have eyesight and are blind. It can survive in the natural environment without any issues. This is because they possess sensory organs which are efficiently stimulated by vibrations and changes with the pressure in water. This stimulation facilitates them to find food and adjust in the dark.
How to build a tetra tank
Most tetras (including cardinal tetras and rummy nose tetras) prefer a basic blackwater setup with botanics and driftwood with hardy plants that survive in blackwater conditions or a community tank with other tetras. Use the substrate you want to build a community tank (gravel or aquasoil) or biotope (sand). Pour a decent amount of substrate into a 20-30 gallon tank and spread it using a substrate spreader. Place the hardscape next. You can use bigger objects for the background and smaller objects in the foreground. Place some plants native to their range depending on the species of tetra you are looking for. You may want to put some root tabs if you have a sandy or gravel substrate. Fill the tank and let it cycle. Put the tetras in the tank.
For Mexican tetras (blind cave form), you need a gravel substrate and some rocks to imitate their natural habitat. You can make stalagmites by carving a tall piece of rock into the shape you want. Repeat that many times until you have the cave feel in your build. The tank size must be 40 gallons or more to hold a school of these fish. Fill the tank and let it cycle. Put the blind cave tetras in.
Tetra care
For most tetras, pH should be between 6.8 and 7.8, alkalinity between 3° and 8° dkH (50 ppm to 140 ppm) and temperature between 75° and 80° F. Exceptions like the Buenos Aires tetra do better in cooler water. For Mexican tetras, they prefer warmer tank temperatures between 68°F and 77°F (20°C to 25°C) and a water hardness around 30 dGH. The Mexican tetra likes neutral to slightly alkaline water as well, so keep the pH between 6.5 and 8.0. You should do a 10-25% water change depending the species of tetra you are looking after.
