Betta fish are known for their aggressive nature, so it is important to choose suitable fish species and arrange an appropriate environment when co-habiting. Generally, betta fish can co-habit with some larger, more docile fish species, such as swordtail fish, moonlight gourami, and discus fish. These fish typically swim quickly and are less likely to become targets of betta fish aggression.
Additionally, if you want to co-habit betta fish with other small fish, it is important to select species that are adaptable and can evade betta fish attacks, such as guppy fish and mandarin fish.

Key Points for Tank Arrangement
When arranging a co-habitation environment, the following points should be noted:
- Provide ample space and hiding spots: to ensure that each fish has sufficient room to move and a sense of security.
- Use adequate filters and air pumps: to ensure clean water quality and sufficient oxygen.
- Line the bottom of the aquarium with fine sand or rocks: to provide hiding and resting places for fish.
- Plant aquatic plants or place driftwood in the aquarium: to offer climbing and resting spots for fish.
Choosing Co-habitation Fish
When selecting fish for co-habitation, it is important to consider their temperament and habits to avoid intense fighting and mutual aggression.
If you have a large aquarium at home and have already kept other types of fish, you can place several isolation boxes in the aquarium and keep the betta fish in these boxes. This way, you can maintain the aesthetic appeal of the aquarium while effectively preventing betta fish from attacking other fish.
