What is freshwater fish?

Freshwater fish are a category of fish species that primarily inhabit freshwater environments, such as rivers, lakes, ponds, and streams, as opposed to saltwater or marine fish that live in oceans and seas. They have adapted to a wide range of conditions and can be found in various regions around the world. These fish are incredibly diverse, with thousands of species recognized by scientists.

Several colorful and ornamental freshwater fish are kept as pets in home aquariums. Guppies, goldfish, tetras, and bettas are some of the most beloved aquarium fish species.

Native Species

Freshwater environments are home to numerous native fish species, which are crucial for maintaining ecosystem balance. These include species like the brook trout in North America or the European perch in Europe.

Invasive Species

Unfortunately, some freshwater fish species are invasive, disrupting local ecosystems when introduced to new areas. The common carp and snakehead fish are examples of invasive freshwater species.

What you shoulder before buying a new freshwater fish

There are several factors to consider before buying a new freshwater fish for your aquarium. Here are a few things to keep in mind:

  1. Compatibility: Make sure that the fish you are considering is compatible with the other fish in your tank. This includes not only the fish's aggression level, but also its size, water temperature, and pH preferences.

  2. Size: Consider the size of the fish when it is fully grown and ensure that it will have enough space to swim comfortably in your tank.

  3. Water parameters: Research the ideal water parameters (such as pH, temperature, and hardness) for the fish you are considering and make sure that your tank can provide those conditions.

  4. Feeding: Research the diet of the fish you are considering and make sure you can provide the appropriate food.

  5. Tank maintenance: Consider how often the fish will need water changes, and how much maintenance the fish will require.

  6. Disease: Research the common diseases and the signs of illness for the fish you are considering and learn how to prevent and treat them.

  7. Compatibility with plants: If you want to keep plants in your tank, make sure that the fish you are considering is not known to eat or damage them.

  8. Life span: Consider the life span of the fish species you are considering. Some species of fish may have a shorter life span, and you may not be ready for another replacement.

  9. Breeding: If you are interested in breeding the fish you are considering, research if it's easy to breed, and if it's legal to breed the fish in your country.

  10. Cost: Consider the cost of the fish, tank setup, and maintenance, and make sure you are prepared to make that investment.


By considering all these factors and doing your research, you can ensure that you are making a wise choice for both you and your new fish.
