Choosing Fish for Your Community Aquarium

By FreshwaterNaturalist.org

So, you’re ready to dive into the world of aquariums—fantastic! Setting up a community tank is a wonderful family project, bringing a slice of underwater serenity into your home. But before you rush to fill your tank with a kaleidoscope of fish, let’s explore how to choose the perfect swimming companions.

1. Start with Beginner-Friendly Fish

For those just starting, beginner-friendly species are key. Look for fish known for their peaceful nature, small size, and easy care. Some great options include:

  • Neon Tetras: Tiny, colorful, and love to school together.
  • Guppies: Hardy, lively, and available in a rainbow of colors.
  • Corydoras Catfish: Bottom-dwellers that help clean up uneaten food.
  • Zebra Danios: Active and hardy, they adapt well to most tanks.

Avoid species like cichlids or fish with special care needs—these are best for experienced hobbyists.

2. Ask Questions and Research

Your local fish store (LFS) is a treasure trove of knowledge. Don’t hesitate to ask questions! Here are some helpful starters:

  • Do these fish get along with others?
  • What size will they grow to?
  • What water conditions do they need?

In addition, spend some time researching online or using trusted aquarium books. A little homework now will save you big headaches later.

3. Match Personalities and Needs

Fish, like people, have different personalities and requirements. To keep your tank peaceful:

  • Choose species with similar temperaments (no bullies allowed!).
  • Ensure they thrive in the same water parameters (temperature, pH, etc.).
  • Avoid overcrowding—each fish needs its own space to swim and feel at home.

4. A Tank for the Whole Family

An aquarium is more than décor—it’s a living ecosystem! Involve the whole family in choosing fish, setting up the tank, and daily care. Kids love watching their new aquatic friends, and it’s a great way to learn responsibility.

5. Plan for the Long Swim

Aquariums are a long-term commitment, so start with a manageable number of fish and add more as you gain confidence. Be patient, as it can take weeks to fully cycle a new tank before introducing fish.

With a little planning, your community aquarium will soon be a beautiful and thriving centerpiece of your home. Ready to start? Visit your local fish store, dive into research, and explore more tips at FreshwaterNaturalist.org.
