Types of Fishkeeping

Fishkeeping is a rewarding hobby that can bring joy to your life. There are two main types of fishkeeping – tropical and freshwater.

Tropical Fishkeeping:

Tropical fish require warmer water temperatures, usually between 75-80°F (24-27°C). They also need more specialized equipment such as an aquarium heater, filter, and lighting system. Common tropical fish include guppies, mollies, platys, tetras, barbs and angelfish. To keep these fish healthy you will need to provide them with the right food for their species and regularly change the water in their tank.

Freshwater Fishkeeping:

Freshwater tanks are generally easier to maintain than tropical tanks because they don’t require special equipment like heaters or filters. The temperature range for freshwater tanks is typically 68-72°F (20-22°C). Popular freshwater species include goldfish, koi carp, cichlids and betta fish. You should feed your freshwater fish a variety of foods including flakes or pellets designed specifically for their type of diet as well as live or frozen foods like brine shrimp or bloodworms occasionally. Water changes should be done weekly to keep the tank clean and healthy for your fish inhabitants.

No matter which type of tank you choose, it is important to research each species before adding them into your home aquarium so that you know what kind of environment they need in order to thrive.

Tropical and freshwater fishkeeping each have their own unique requirements and considerations. By understanding the differences between them, you can set up a successful aquarium that will bring joy to your home for years to come. Let’s look at how to get started by exploring the equipment needed for each type of fishkeeping.

Setting Up the Aquarium

Setting up an aquarium can be a fun and rewarding experience. Whether you’re looking to set up a tropical or freshwater tank, there are some basic pieces of equipment that you will need.

Equipment Needed for Tropical Fishkeeping:

A good quality filter is essential for any tropical fish tank. It helps keep the water clean and free from debris, as well as providing oxygenation for your fish. You will also need an air pump to provide additional aeration in the tank, and a heater to maintain the temperature at around 78-82 degrees Fahrenheit (25-28 degrees Celsius). Other items such as gravel, decorations, plants, lights and thermometers may also be necessary depending on what type of fish you plan on keeping.

Equipment Needed for Freshwater Fishkeeping:

For freshwater tanks it is important to have a good quality filter with multiple stages of filtration including mechanical filtration (removing large particles), biological filtration (breaking down ammonia) and chemical filtration (removing toxins). An air pump should also be used if needed to increase oxygen levels in the water. Depending on what type of fish you plan on keeping other items such as gravel, decorations, plants and lights may also be necessary.

When aquascaping, it is important to not overcrowd the tank; leave plenty of open space between objects so that your fish have room to swim freely without feeling cramped or stressed out by their surroundings.

With the right equipment and a bit of creativity, setting up an aquarium for either tropical or freshwater fish can be an enjoyable and rewarding experience. Now that you have your tank ready to go, let’s take a look at how to properly care for and maintain it.

Key Takeaway: Aquariums require different types of equipment depending on whether they are tropical or freshwater. For both, a good quality filter is essential and an air pump should be used to increase oxygen levels in the water. Other items such as gravel, decorations, plants and lights may also be necessary depending on what type of fish you plan on keeping. Finally, it’s important to leave plenty of open space between objects so that your fish have room to swim freely.

Care and Maintenance

Feeding Requirements for Tropical Fish:

When it comes to feeding tropical fish, it is important to provide them with a balanced diet. A variety of foods such as flakes, pellets, freeze-dried and frozen foods should be offered in small amounts several times per day. It is also important to remember not to overfeed your fish as this can lead to health problems and water quality issues.

Feeding Requirements for Freshwater Fish:

Feeding freshwater fish requires a bit more knowledge than tropical fish since there are many different types of species that require specific diets. Generally speaking, most freshwater fish will do well on a combination of high-quality flake or pellet food supplemented with occasional live or frozen foods like brine shrimp or bloodworms. It’s best not to feed your fish too much at once; instead spread out their meals throughout the day so they have time to digest their food properly.

Maintaining good water quality is essential for keeping healthy pet fish. This means regularly testing the pH levels, ammonia levels, nitrite levels and nitrate levels in the aquarium using test kits available from pet stores or online retailers. Additionally, regular partial water changes (10-15%) should be done every week or two depending on how heavily stocked the tank is with livestock and plants. Finally, make sure you use an appropriate filter system for your aquarium size; this will help keep debris from building up which can cause poor water conditions if left unchecked.


In conclusion, tropical vs freshwater fishkeeping is a great way to get started in the hobby of keeping pet fish. Whether you choose to keep tropical or freshwater species, there are many options available for setting up an aquarium and caring for your fish. With proper research and preparation, you can ensure that your tank will be a safe and healthy environment for your new pets.
