How Many Female Bettas Can I Put in a 10 Gallon Tank?

How Many Female Betta Can I Have in a 10-Gallon Tank? The short answer is that keeping four to five females in the tank is advisable.

If you are keeping more than five, the risk of aggression increases, and there needs to be more space for them to thrive. 

Female Bettas can be very territorial when kept together, so proper tank size, décor, water quality, and gender ratio play an important role in happy cohabitation.

Housing too many fish will create overcrowding and stressed-out bettas due to competition for food, territory, or hiding places – this can lead to increased levels of aggression between the fish that may result in injuries or even fatalities. 

Providing plenty of covers, such as live plants or other structures like driftwood, also gives the female bettas something else on which they can focus their territorial behavior; this reduces the chances of injury resulting from fights with other tank mates.

In addition, adding floating plants like Water Lettuce will protect from direct light (a stressor) while offering surface area with much-needed oxygen exchange via its numerous roots below the waterline. 

Finally, regular partial water changes should be done at least once a week – up to twice weekly depending on the bio load in your aquarium – keeping nitrate levels low is key for healthy Betta lifestyles!
