Keeping pet fish is truly exhilarating. Fish are delightful and can play a significant role in your life if you let them.

Freshwater fish often include tropical or cold water species.

Tropical fish aquariums will require a warm temperature ranging from 24oC to 27oC (75oF to 80oF) for the fish to thrive. For cold water aquariums, you will need goldfish and other breeds that do not need a heating apparatus.

When decorating your aquarium, you may use gravel, rocks, live or plastic plants, and plastic sculptures.


What Factors Should You Consider?

When you visit an aquarium, you will be surprised at the assortment of fish in the aquarium. Of all these species, not all may be suitable for a beginner-level aquarist.

It is wrong to purchase fish without knowing some basic factors about them. to determine whether or not they can thrive in your aquarium. Most hobbyists buy fish without the faintest idea of what it eats, how big it can get, or unusual care requirements. Although acquiring new fish for your aquarium is always fun, it could be disastrous and expensive if you do so aimlessly.

So, whether you are adding more fish to your aquarium or starting a new one, below are some of the criteria to look out for:


Fish Compatibility

The best freshwater aquarium fish combination is made up of a variety of fish breeds living happily in your aquarium. To properly mix these different fish, you need to choose fish that are compatible with each other. Do not combine aggressive fish with fish breeds that are peace-loving, as this could lead to the death of your peaceful fish breed.

Also, some fish are very active and require a lot of open space to swim around and nooks to hide in.

No matter how easy your freshwater fish are to care for, they still have specific needs. Some of these needs are water composition, plant preferences, and temperature. It will be better if you get fish species with similar needs that can live under similar conditions.

Hence, the fish in your aquarium must have compatible personalities. This will make your aquarium easier to take care of and keep your fish healthy.


Your Experience

Your experience in taking care of fish also matters. It will be frustrating if an inexperienced aquarist decides to buy fish breeds that are recommended for more experienced aquarists.

Aquarium Size 

Most freshwater fish are social, so they do very well in a group. When thinking of what kind of fish to add to your aquarium, consider how big it can grow and how many fish you will need to have a comfortable group. Larger, social fish will need many buddies and require a larger-sized aquarium to stay healthy. Smaller fish do well in a smaller aquarium.

Also, do not forget that your aquarium will need space for plants and other elements.


Aquarium Set-up

A typical aquarium set-up is not only made up of the fish. Furnishings like gravel, rocks, background, driftwood, plants (live or plastic), and other decorations are part of your aquarium. For a cover, you may use a canopy. 

Other things you need are aquarium stand, heater, lighting, thermometer, filtration apparatus, fish food, air pumps, air stones, fishnet, water quality testing kits, water conditioner, siphon hose, and bucket for changing water.

Also, there are height and surface area to consider in setting up and maintaining a living biotope. The surface area contributes to supplying excellent in-tank oxygenation and helps in creating amazing aquatic themes.


Aquarium Material

It is always better to go for all-glass aquariums because they are more reasonably priced and resist discoloration and scratches better.

Professional Recommendation: Before you add freshwater fish to your aquarium, first do your research. Know the needs of each fish you are adding to the tank. Also, get professional advice from the aquarium store.
