Spread the love

If you’re thinking about getting an aquarium fish and looking for some fish to live in it, you’ve come to the right place! In this article, you’ll learn about Cory catfish, Swordtails, Black Phantom Tetra, and Congo tetra. If you’re not sure where to start, consider starting with one of these popular species. The right home aquarium for each of these species will help you get started on the right foot.

Cory catfish

Cory Catfish are opportunistic feeders that need a well-balanced diet. They eat sinking pellet food, small insects, frozen bloodworms, and tablets. Occasionally, they will eat pieces of vegetables. Corys are sensitive to stress and may develop certain diseases. This article will discuss some of the things to keep in mind before starting a Cory fish tank. The first thing you should know about Corys is how to care for them.

If you’re looking to keep Corys as pets, it is important to keep the water in the tank at a pH level of 7.0 to 7.8. Cory catfish in their natural habitat live in slow streams. Corys thrive in a tank with a pH level between 6.0 and 8.0. However, they can become stressed by a sudden change in pH level. You can also test the water for ammonia and nitrite, which are poisonous to fish. Adding a teaspoon of tonic salt to the water in your tank once a week will help keep them healthy and happy.


Originally from Central and South America, swordtails have undergone extensive breeding and domestication. There are countless varieties of swordtail available, including red wag, marigold wag, and hi fin lyretail. These specialty swordtails are derived from multiple generations of inbreeding. Some may be short-lived or have a reduced immune system. If you’re not sure which fish to purchase, consider the following:

Swordtails are viviparous, meaning they give birth to many fry in a single spawn. Their fertility varies according to the mother’s age, size, and living conditions. You can easily spot pregnant swordtails by their distinctive rounded bodies, and even notice the females slowing down and developing a pot belly. Once these females reach reproductive maturity, they will be ready to produce babies.

Congo Tetra

The most common problem with this tropical fish is that they are not very picky eaters. However, this should not put you off acquiring one! They are opportunistic omnivores, and will happily eat almost anything in the tank. The good news is that they are extremely hardy. As long as you provide the right environment, your Congos should be healthy and happy. Here are some tips to help you raise a healthy population of these fascinating fish.

In the wild, Congo tetras live in dark, heavy-silt conditions. The water is low-visibility and slightly acidic. They hide in thick plant cover to avoid being discovered. In captivity, they can reach a length of almost 4 inches (11.5 cm), but in the aquarium, they are smaller than their wild counterparts. Female Congo tetras only reach a length of about 2 inches (5 cm) in the wild, so it’s best to keep them in groups of at least 10 to avoid being overwhelmed.

Black Phantom Tetra

If you’re considering adding a Black Phantom Tetra to your aquarium, make sure you have plenty of space for it. These fish need at least 20 gallons and 24 inches of tank space. This tank size is ideal for groups of six fish, but if you want a larger group, you’ll need to go higher. Once your Black Phantom has settled in, he will start eating and living happily. Just be sure to clean the tank regularly to prevent water pollution.

If you’re not sure whether to get a single-species tank or a community tank, Black Phantom Tetras can easily adjust to both environments. Ideally, they should be introduced in groups to avoid aggression and ensure that there are no aggressive tank mates. If you’re looking for the most peaceful aquarium, a single male with several females is best. If you’re not sure whether to get a male or a female, make sure the mate you choose is compatible with Black Phantoms.
