The right aquarium fish can make all the difference. Here’s 6 great tips to help you choose the best beginner fish as you embark on your aquarium keeping adventure!

Choosing your first aquarium fish may seem like a daunting task for a beginner. However, with a little research, you will be able to know what fish will prove to be hardy, undemanding, and well-suited to beginners. Perhaps the pet store may have recommended guppies, neons, or catfish, but many beginners have found it difficult to raise them, considering that they are still learning the ropes of aquarium fish care.

These six important tips will help you pick your first aquarium fish. Taking care of these fish species will certainly be a rewarding undertaking that will fuel your love for the hobby.

1. Choose fish which can easily adapt to new surroundings

A good first species should be one that is hardy, active, confident, and disease-resistant. Select fish that appear healthy. Avoid fish that manifest visible signs of disease such as white spots, discolored skin patches, frayed fins, etc. Make sure that the fish can withstand water fluctuation since a new tank often has fluctuations in water quality that can stress your fish.

Aside from water conditions, your new fish should be able to adapt well to the presence of aquarium decorations and to the company of other fish species in the tank. Large or active fish can thrive well alone in a tank with little aquarium decor. However, there are fish species that find being alone distressing. Even with excellent water quality, you may find your pet hiding, not feeding, and may become vulnerable to illness.

2. Avoid fish with known specific feeding habits

Pick a fish species that can be fed a simple flake food for the first 6-8 weeks. Fish with specific feeding habits may result in excess amounts of waste products leading to high ammonia and nitrites in the water. The accumulation of these compounds is hazardous to your fish population.


3. Select fish from the same community

Selecting fish species from the same community will help ensure that you achieve balance in your aquarium. If you choose to get several varieties, make sure that they will get along well. Be sure to select the hardiest species. Fish that belong to the same community will have similar water chemistry and temperature requirements while exhibiting like behavior.

4. Start with peaceful community fish species

Aggressive tropical fish species may need to be fed live feeder-fish and this can certainly add up on your list of responsibilities. It is important to know which aggressive fish species can be matched, or else your peaceful community fish species may end up being eaten by its more aggressive tank mates. Aggressive fish species also need more tank space. Some of the tropical fish species that can thrive well in a community tank include tetras, gouramis, and platys.


5. Don’t buy too many at once

You must stock your aquarium slowly. Being a neophyte, you run the risk of losing large numbers of fish to disease or bad water quality. Putting in many fish at the onset may overload the new tank water and lead to a build-up of ammonia. The size and type of your tank and aquarium filter will help determine the amount and frequency of introducing new fish species to your tank. As a rule of thumb, no more than six small fish species should be added every seven days.

6. Buy from reputable breeders and pet shops

Before buying fish from a breeder or pet shop, it is recommended to visit the establishment and observe how they take care of the fish. You can see for yourself if the fish has a healthy appetite or is suffering from any health problems or defects. Never buy fish from aquarium shops that are not particular about maintaining hygiene and sanitation in their tanks. Pet shops that allow dead fish floating inside the tank or fail to quarantine sick fish should never be patronized.
