Do Betta Fish Need Tank Mates?

The Betta Fish live a solitary life and they do not like tank mates. However, if they are in the small tanks, they might get bored. You can add the numerous species as tank mates in your Betta’s tank under specific conditions. To add the species into the tank, you must increase the size of the tank and add a filtration system to keep the species healthy and clean.

Can You Put Multiple Bettas in the Same Tank?

The male bettas can be stressed and aggressive against the other male bettas or if they are housed together with other fishes. They should not be kept with female bettas or other male bettas in the same container; it is recommended to create a separate five-gallon tank for your male bettas. The Female bettas are less aggressive, and they can live with other female bettas in the same container.

While choosing the tank mates for your Betta fish, ensure that the tank mates can flourish in the same water conditions and habitats your betta fish does. Before adding any fish to the community tank of Betta, you must take the following precautions.

  • Make sure the other fishes you have chosen for your betta fish are free of any parasites and have no disease.

  • Clean the tank before adding the tank mates.
  • Check the water conditions including the Temperature and PH. The temperature should be between 76- and 83-degrees Fahrenheit and the PH must be between 6.8 to 8.

What Species Cannot Live with Bettas?

The following fishes cannot live with bettas:

–       Angelfish: The Angelfish require the same water condition as your Betta does, but they are more aggressive towards other species. You should not keep them in the tank of your Betta Fish.

–       Cichlids: Just like Bettas, they also have a territorial nature and end up fighting with Bettas.

–       Gouramis: They look similar to Bettas and become competitors.

–       Tiger Barbs: They nip the fins of other fishes and if you choose them as a tank mate for your Betta Fish, they will tear apart the fins of your fish.

–       Fancy guppies: They have long and colorful fins that end up leading to potential harm to both species.
