Betta fish are loved for their vibrant colors and flowing fins, making them a favorite among enthusiasts. However, their reputation for being territorial often leaves people hesitant to introduce other tankmates. The good news is that Betta fish can coexist harmoniously with other species if the right companions are selected. Selecting companions that are calm, non-aggressive, and unlikely to provoke your Betta is essential. Here, we’ll explore the 10 best tankmates for Betta fish, helping you create a harmonious, lively, and visually stunning aquarium that you and your Betta will adore.
1. Neon Tetras

Neon Tetras are small, colorful fish that are perfect for Betta tanks due to their peaceful nature. Their shimmering blue and red stripes complement the Betta’s vibrant hues, creating a visually stunning setup. Neon Tetras are schooling fish and prefer to swim in groups of six or more, which helps them stay active and stress-free. Furthermore, they occupy the middle of the tank, steering clear of the Betta’s preferred zones. Neon Tetras also thrive in water conditions similar to Bettas, making them easy to care for. By adding plants and hiding spots, you can ensure a harmonious coexistence.
2. Corydoras Catfish

Corydoras catfish are excellent companions for Betta fish, as they prefer the bottom of the tank, avoiding the Betta’s space. Their peaceful demeanor and helpful scavenging habits make them a practical addition to any aquarium. They clean up leftover food, promoting a healthier environment. Additionally, Corydoras thrive in groups of three or more, which makes them feel more secure and active. Sharing similar water preferences with Bettas, they are easy to maintain in the same setup. With their gentle behavior and functional role, Corydoras catfish add diversity and charm to your Betta tank while keeping it clean.
3. Harlequin Rasboras

Harlequin rasboras are graceful and peaceful fish characterized by their striking orange and black colors, making them an excellent addition to Betta tanks. These shoaling fish thrive best in groups of six or more, which helps them feel secure and showcase their natural behaviors. They typically swim in the middle levels of the tank, minimizing interactions with the Betta, which tends to inhabit the upper layers. Harlequin Rasboras also prefers slightly acidic water, aligning well with the optimal conditions for Bettas. Adding these vibrant fish to your aquarium can foster a dynamic and harmonious aquatic environment that highlights the beauty of both species.
4. Kuhli Loaches

Kuhli Loaches are quirky, eel-like fish that add character to your Betta tank. These nocturnal creatures are shy and spend most of their time hiding during the day, reducing interactions with Betta fish. Moreover, Kuhli Loaches are excellent at cleaning the substrate, consuming leftover food, and helping to maintain water quality. They thrive in groups of three or more and need plenty of hiding spots, such as caves or plants, to feel secure. With their peaceful nature and useful habits, Kuhli Loaches are ideal companions for Betta fish, enhancing the tank’s diversity and cleanliness.
5. Ember Tetras

Ember tetras are tiny, orange fish that bring warmth and energy to your aquarium. Their calm nature and schooling behavior make them perfect companions for Betta fish. Swimming in groups of at least six, they prefer the middle layers of the tank, keeping clear of the Betta’s territory. Additionally, their bright orange hues complement the Betta’s striking colors, creating a visually stunning aquarium. Ember tetras thrive in stable water conditions and enjoy planted tanks with hiding spots. By adding them to your tank, you can create a peaceful and colorful environment where both Bettas and Ember Tetras thrive together.
6. Snails

Snails are an excellent non-fish option for Betta tanks, offering both aesthetic appeal and practical benefits. Popular choices like Nerite and Mystery snails feed on algae and leftover food, reducing tank maintenance. Their tough shells protect curious Betta nips, ensuring peaceful coexistence. Snails are easy to care for and do not compete for space or food with Bettas. However, it’s important to avoid overcrowding, as too many snails can lead to excess waste. With their calming presence and functional role, snails are a unique and beneficial addition to any Betta aquarium setup.
7. Ghost Shrimp

Ghost shrimp are fascinating tankmates for Betta fish due to their transparent bodies and functional behavior. They are peaceful scavengers feeding algae and leftover food, contributing to a cleaner tank environment. Ghost shrimp are small and tend to stay out of the Betta’s way, making them compatible companions. However, some Bettas may see shrimp as prey, so providing plenty of hiding spots like plants or decorations is essential. Ghost shrimp are low-maintenance and thrive in water conditions similar to Bettas. Their unique appearance and helpful nature make them a practical and interesting addition to your aquarium.
8. Otocinclus Catfish

Otocinclus catfish, commonly known as “Otos,” are small, peaceful algae-eaters that are a practical choice for Betta tanks. They spend most of their time cleaning plants, decorations, and other surfaces, which helps maintain water quality. Otos are naturally shy and prefer to live in groups of three or more, reducing stress and encouraging natural behaviors. Furthermore, they rarely interact with Betta fish, ensuring a harmonious tank environment. With proper care and plenty of hiding spots, Otos thrive alongside Bettas, making them a functional and low-maintenance addition to your aquarium.
9. Cherry Shrimp

Cherry shrimp are vibrant, red-colored shrimp that add beauty and functionality to your aquarium. These peaceful creatures spend their time scavenging for algae and leftover food, keeping the tank clean. Their bright red coloration contrasts beautifully with Betta fish, creating an eye-catching setup. Cherry shrimp thrive in planted tanks with plenty of hiding spots, which also help protect them from curious Bettas. While some Bettas may view shrimp as a snack, proper tank setup can minimize risks. Cherry shrimp are a fantastic addition to Betta tanks, offering aesthetic appeal and practical benefits to your aquatic environment.
10. African Dwarf Frogs

African Dwarf Frogs are playful and unique companions that can live peacefully with Betta fish. These amphibians are bottom-dwellers, which helps them avoid confrontations with Bettas. They thrive in similar water temperatures and conditions, making them easy to care for in the same setup. However, feeding them separately is important, as they eat more slowly than Betta fish. Providing plenty of hiding spots and a soft substrate ensures their comfort and safety. Their quirky behaviors and distinctive appearance make African Dwarf Frogs an engaging and harmonious addition to your Betta’s aquarium.
