At Cuaquatics, we specialize in offering a diverse and healthy selection of freshwater fish perfect for all types of tank setups.

Why Freshwater Fish Are Perfect for Your Aquarium
Freshwater fish are among the most popular choices for home aquariums—and for good reason. They are generally easier to care for compared to saltwater species, making them ideal for beginners. Freshwater species also come in a wide array of colors, sizes, and temperaments, allowing aquarists to create beautifully balanced communities.
At Cuaquatics, we understand that every aquarium setup is unique. That’s why we offer handpicked freshwater fish, ethically bred and health-checked to ensure the best possible experience for our customers across the UK.freshwater fish
Benefits of Keeping Freshwater Fish
1. Ease of Maintenance
Freshwater aquariums are more forgiving when it comes to water parameters, filtration, and overall care routines. This makes them especially attractive to new fishkeepers.
2. Affordable Setup and Maintenance
Unlike saltwater systems, freshwater tanks don’t require expensive lighting, protein skimmers, or elaborate filtration. Plus, freshwater fish and supplies tend to be more budget-friendly.
3. Diverse Fish Species
From neon tetras to angelfish, freshwater aquariums offer a wide spectrum of species that cater to all preferences—whether you’re looking for schooling fish, bottom-dwellers, or showstoppers.
Best Freshwater Fish to Add to Your Aquarium
At Cuaquatics, we take pride in offering a carefully curated selection of freshwater fish. Below are some of our most popular picks:
1. Neon Tetras
A staple in community aquariums, neon tetras are small, colorful, and peaceful. They do best in groups of six or more and love planted tanks.
2. Guppies
Guppies are known for their vibrant colours and active personalities. They’re also livebearers, which makes them exciting to watch if you’re interested in breeding.
3. Corydoras Catfish
These bottom-dwellers are peaceful and excellent tank cleaners. They prefer to be in small groups and thrive in soft, sandy substrates.
4. Angelfish
Elegant and eye-catching, angelfish are a fantastic centerpiece for medium to large aquariums. They do well in community settings with compatible tankmates.
5. Cherry Barbs
Another peaceful schooling fish, cherry barbs are known for their bright red hue and adaptability to a range of water conditions.
6. Mollies and Platies
Both of these are hardy, colorful, and easy to breed—ideal for beginners. They do best in planted tanks with stable water conditions.
Creating the Perfect Freshwater Aquarium Setup
Designing a freshwater tank goes beyond just choosing the right fish. Here’s how to set your aquarium up for long-term success:
1. Select the Right Tank Size
Start with at least a 20-gallon tank to provide sufficient space and stable water parameters. A larger tank allows for a more diverse community of freshwater fish.
2. Establish Water Quality
Test and maintain ideal water parameters—pH, ammonia, nitrite, and nitrate levels—to support fish health. Use water conditioners and filters designed for freshwater systems.
3. Add Live Plants and Decor
Live plants not only improve oxygen levels but also offer hiding spaces and a more natural environment. At Cuaquatics, we also supply aquatic plants that pair perfectly with your freshwater fish.
4. Use Compatible Tankmates
Always research compatibility when mixing species. Aggressive fish should never be housed with peaceful ones, and schooling fish thrive best in groups.

Tips for Choosing the Right Freshwater Fish
- Understand Fish Behavior
Some fish prefer solitude, while others thrive in schools. Choose according to your tank size and setup. - Check Compatibility
Ensure the fish you’re selecting can cohabitate peacefully with existing tank mates. - Match Water Requirements
Group fish with similar pH and temperature needs to minimize stress and health issues. - Start Slow
Introduce fish gradually to allow the tank’s ecosystem to adjust and prevent overloading your filtration system.
