Are you looking to add a burst of colour and liveliness to your aquarium? Tetra fish are an excellent choice. With their striking appearance and peaceful nature, they make a fantastic addition to any freshwater tank. But with so many species available, how do you choose the best ones for your setup? In this blog, we’ll guide you through the top 5 tetra fish species you should consider adding to your aquarium.
Whether you’re a seasoned aquarium enthusiast or just starting, these tetras will bring beauty and excitement to your tank. Plus, with the right care and attention, they’ll thrive in your home.
1. Neon Tetra – The Colourful Favourite
If you’re after a fish that’s both eye-catching and easy to care for, the Neon Tetra is a top contender. Known for their bright blue bodies and a striking red stripe running down the length of their body, these small fish are a staple in many aquariums. Neon Tetras are peaceful, making them a perfect choice for community tanks. They typically grow to around 3.5 cm, so they don’t take up much space, and they prefer schools of six or more to feel secure and display their full potential.
These little beauties thrive in water temperatures ranging from 22°C to 28°C and a pH level of 6.0 to 7.5. Since they are non-aggressive, Neon Tetras do well alongside other peaceful species. Just remember, they need a well-planted tank with plenty of hiding spaces, as they feel more at ease when they can dart in and out of plants and decorations.
You can find quality Neon Tetras at Go Fish Aquariums – they’ll add a delightful splash of colour to your setup. For tank accessories, be sure to visit our stockists for everything else you need to complement your tank’s décor and provide a healthy environment for your fish.
2. Cardinal Tetra – A True Gem for Your Aquarium
The Cardinal Tetra is another stunning species known for its vibrant colours. Their red and blue hues are even more pronounced than those of the Neon Tetra, making them one of the most beautiful fish species in the aquarium world. These fish have a red stripe that stretches the length of their body, complemented by iridescent blue scales on the upper half.
Cardinal Tetras are peaceful and prefer to live in groups. They thrive in slightly warmer water, with a temperature range of 24°C to 28°C, and they appreciate soft, slightly acidic water. At around 4 cm in length, they fit comfortably into most tank sizes, but they do need plenty of space to swim freely.
When adding Cardinal Tetras to your aquarium, ensure you provide a well-planted environment with dim lighting. The plants and dark substrate will highlight their brilliant colours and make them feel more at home. As with all Tetras, you can find them at Go Fish Aquariums and visit our stockists for any necessary accessories.
3. Rummy Nose Tetra – The Perfect Schooling Fish
Rummy Nose Tetras are well-known for their striking appearance and strong schooling behaviour. With their shimmering silver bodies and a distinctive red nose, they add a unique charm to any tank. Their tails feature a striking black-and-white striped pattern, making them stand out even more in a planted aquarium.
These fish thrive in slightly acidic water with a pH range of 5.5 to 7.0 and a temperature of 24°C to 27°C. They grow to about 5 cm and require a group of at least six to exhibit their best schooling behaviour. Rummy Nose Tetras are peaceful and do well with other community fish.
Add Rummy Nose Tetras to your aquarium by visiting Go Fish Aquariums. For tank accessories and decorations, be sure to check out our stockists.
4. Ember Tetra – A Small Fish with a Big Personality
The Ember Tetra is a tiny but lively fish that can bring a vibrant touch to your aquarium. With their bright orange-red bodies, these fish create a stunning visual effect, especially when kept in groups. Despite their small size—usually around 2 cm—they have big personalities and enjoy swimming actively throughout the tank.
Ember Tetras prefer water temperatures between 23°C and 28°C and a pH level of 5.5 to 7.0. They do best in a densely planted tank with subdued lighting to enhance their fiery colour. Since they are peaceful, they make excellent tank mates for other small, non-aggressive species.

5. Lemon Tetra – A Bright Addition to Your Aquarium
The Lemon Tetra is another colourful species that’s perfect for adding a burst of brightness to your aquarium. With their yellowish hue and peaceful nature, these Tetras bring both charm and beauty to any tank. Lemon Tetras are small, reaching around 4 cm in length, and they’re best kept in groups of six or more.
These fish prefer slightly acidic water with a pH level between 5.5 and 7.0 and temperatures ranging from 22°C to 28°C. Lemon Tetras are a bit more sensitive than other species, so it’s essential to maintain stable water conditions. They do best in tanks with plenty of plants and a soft substrate, which will make them feel secure and comfortable.
