Here are the suitable fish species for cohabitation with betta fish, along with relevant precautions:
I. Recommended Cohabitant Fish Species
Small, Fast-Swimming Fish
Zebra Danios: Boasting distinct black and white stripes, they are fast swimmers with a mild temperament and high survival rates.
Neon Tetras/Cardinal Tetras: Highly social and schooling fish, they can distract bettas. It is advisable to keep them in a ratio of at least 3:1 (relative to bettas).
Platies/Mollies: These fish have strong disease resistance, vibrant colors, and agile movements.
Bottom-Dwelling Fish
Plecostomus/Algae Eaters: Their activity area does not overlap with that of bettas, and they can help clean the fish tank by feeding on algae.
Corydoras Catfish: With a gentle nature and strong adaptability, they mainly stay active at the bottom of the tank.
Medium-Sized, Gentle Fish
Angelfish: They have a docile temperament and a slightly larger size, so it is important to match their size with that of the bettas.
Discus Fish/Pineapple Fish: Though relatively large in size, they have a mild disposition.
II. Key Conditions for Cohabitation
Tank Environment
The tank should have a capacity of at least 40 liters, and it is recommended to be over 60 centimeters in length to provide sufficient space for the fish to move around.
Set up shelters such as aquatic plants and driftwood to reduce territorial conflicts.
Breeding Management
Introduce other fish into the tank first, and then add the betta fish to reduce its aggressiveness.
Avoid cohabiting with slow-swimming or aggressive fish species (such as guppies and tiger barbs).
III. Precautions
Male Betta Fish: It is recommended to keep them alone, as male bettas of the same species are prone to fierce fights.
Water Quality Maintenance: Maintain the water temperature between 22-28℃ and the pH value between 6.5-7.5, and change the water regularly.
By selecting appropriate fish species and arranging the tank environment reasonably, betta fish can coexist harmoniously with the above-mentioned fish species.
