Betta Fish Breeding:

Do not mix up 2 males, or a male & female in one aquarium unless breeding. For breeding purpose, keep both male & female together for a shorter period, & then separate them. Bettas are aggressive & they try to hurt each other which might cause death or one of the fish might be severely stressed.

Females can live in union of 5 or more but needs large aquarium. Make sure you follow a good rule of thumb of having 1 gallon of water per 1 inch of each fish. For example, having 6 females, each 2 inches need 12 gallons of aquarium.

During breeding period, when betta fish become highly exalted, they show brighter colors that appears to be more saturated & this is the way to recognize female beta of their purpose.

Some betta types are very aggressive & they don’t want to share same aquarium with mates, but others are happy to live with other species that are not aggressive & do not have bright colors or long fins.

You can keep mates with betta if you have larger aquariums with many hiding spots. It is advised to have a tank that can hold 8 or more gallons of water to offer a number of hiding places for your betta.

More space in big aquariums will reduce the territorial instincts of the fish & may lower its aggression against certain kind of species.

Do not put 2 male bettas in one aquarium because they will fight till death or unless one of them is very stressed. This is a gruesome process & should be avoided. Do not put a male with a female unless they are breeding. Use a divider to isolate 2 bettas.


Water Temperature For Betta:


Ideal Water Temperature for Betta
Ideal Water Temperature for Betta


  • Ideal water temperature for betta is 76 – 81 degrees Fahrenheit
  • Bettas like to live in water in pH range of 6.5 to 7.5
  • Add de-chlorinated water to aquarium
  • Monitor temperature of water using a thermometer
  • Use filter to control levels of toxic components
  • Avoid quick changes in temperature of water because it can put your betta in stress. Also quick increase in water can help algae growth.

Bettas come from a tropical climate of Thailand so they love to live in warmer water in aquariums. Make sure aquarium water does not drop below 65 degrees or rise over 82 degrees, but try to maintain them in an ideal temperature range of 76 to 81 degrees Fahrenheit. In this temperature, bettas are very active.


Aquarium Filter For Betta:

Make sure you have a running filter in aquarium to minimize the risk of losing betta or putting it in stress. They decrease level of toxic bacteria & help in growth of beneficial bacteria. Filters are cheap & required for aquariums.

Betta do not swim too much & filters can put them in stress if it releases strong current of water. Putting betta in such tank for prolonged period of time can lead to ripped fins, stress, & could be the reason behind their death. Make sure your filter is adjustable or recommended for betta fish.

Aquariums that can hold under 3 gallons of water will require more frequent & full water changes so that high buildup of ammonia can be wiped out. However, tanks greater than 3 gallons require cleaning based on its size & also how much water to be changed is based on how much water it can hold.

Aquariums with no filter need 1-2 water cycles of 25 percent of full volume & a complete water change every week based on quality of water. If your aquarium can hold 5 gallons of water, then it will only require 1-2 water cycles in a week of 25 percent & a full water change once in a month based on quality of water.

Make sure you fill your tank with de-chlorinated water & temperature of water adding to aquarium is the same as that of aquarium water.
