What Tropical Fish Should I Buy?

Starting your journey into the world of tropical fish keeping is exciting, relaxing, and visually rewarding. But with so many species available, it can be a little overwhelming deciding which tropical fish are best for your aquarium. At Di

scount Aquatics, we’ve helped thousands of fishkeepers—beginners and experts alike—choose the perfect additions to their tanks.

Whether you're setting up a small community tank or building a vibrant underwater world, here's our guide to choosing the right tropical fish for you.

1. Consider Your Aquarium Size

Not all tropical fish thrive in the same space. If you have a smaller tank (under 60L), consider peaceful species like:

• Neon Tetras

• Guppies

• Zebra Danios

• Corydoras Catfish

Larger tanks open up options like:

• Angelfish

• Gouramis

• Swordtails

• Rainbowfish

  
  

2. Think About Compatibility

Some tropical fish are peaceful and thrive in a community, while others can be territorial. At Discount Aquatics, we recommend starting with peaceful fish that get along well with others. Popular community fish include:

• Mollies

• Platies

• Cherry Barbs

• Rasboras

Avoid mixing aggressive or semi-aggressive species unless you have experience managing tank dynamics.

3. Low Maintenance Fish for Beginners

If you're new to the hobby, look for hardy tropical fish that are forgiving to beginners. Our top picks:

• Guppies

• Mollies

• Bristlenose Plecos

• Kuhli Loaches

All of these species are available at great prices from Discount Aquatics, with expert advice to ensure you’re set up for success.

4. Brighten Your Tank with Color

Want to add a splash of color? Some of the most vibrant tropical fish include:

• Betta Fish (best kept solo)

• Dwarf Gouramis

• Electric Blue Rams

• Cardinal Tetras

These fish are as beautiful as they are peaceful, and many are featured in our Discount Aquatics weekly deals.

5. Check Water Requirements

Different fish prefer different temperatures and pH levels. Always check compatibility before buying. Our team at Discount Aquatics can guide you in balancing your tank conditions and recommend products to keep your water stable and healthy.
