Why Freshwater Fish Make Great Pets

Freshwater fish are among the most popular pets in the UK for good reason. They’re beautiful, low-maintenance, and fit comfortably into homes and offices alike. Freshwater aquariums bring a sense of tranquillity to any space, offering visual appeal and stress relief through gentle movements and vibrant colours.

Whether you’re interested in small schooling fish like neon tetras or more unique species like dwarf gouramis or angelfish, the freshwater fish world is filled with variety. With proper care, many species can live for several years, offering a long-term hobby full of learning and joy.

Ethical Breeding and Sustainable Practices

At Cuaquatics, our commitment goes beyond selling freshwater fish—we promote sustainability and ethical breeding. We collaborate with trusted UK breeders who raise fish in humane, stress-free environments. By reducing reliance on wild-caught stock, we help preserve natural ecosystems and provide our customers with fish that are hardier and better adapted to tank life.

Freshwater Fish for Every Tank

No matter your tank size or level of experience, we have the right freshwater fish for you.

• Small Tanks (20L–60L): Betta fish, endlers, pygmy corydoras
• Medium Tanks (60L–120L): Mollies, platies, swordtails
• Large Tanks (120L+): Angelfish, discus, rainbowfish

We also provide aquatic plants, filtration systems, and food to keep your fish healthy and your tank ecosystem balanced.

Freshwater Fish Care Tips

To ensure your fish thrive, follow these essential care practices:

• Cycle your tank before introducing fish to establish beneficial bacteria.
• Maintain stable water conditions using regular testing for pH, ammonia, nitrite, and nitrate.
• Feed a varied diet appropriate for the species—flake food, pellets, frozen or live food.
• Monitor fish behaviour for signs of stress or illness.
• Perform regular water changes (typically 20–30% weekly).

Proper care not only improves lifespan but also enhances colouration and activity levels.
