Tips for Success in a Betta Community Tank
Add the Betta Last: Add the other fish first. Let them establish their territories. Add the betta a few days later to reduce territoriality.
Feed Appropriately: Ensure everyone is given the proper food. Bettas are given floating pellets, and bottom dwellers are given sinking wafers.
Maintain a Spare Tank: A spare or quarantine tank is handy in the event of aggression or sickness.
Watch Closely: Particularly the first week. All bettas are a little unique as far as temperament goes. Some are calm; some are lone wolves.
Conclusion
While betta fish are solitary by nature, with proper planning and attention, some species can be kept with them. Understanding their nature, introducing an appropriate environment, and selecting compatible tankmates are the rudimentary steps in creating a peaceful and colourful aquarium.
While betta fish are territorial as well, they can be kept with some tank mates peacefully if careful planning and care are employed. With the right species, sufficient space, and perfect water conditions, you can enjoy a peaceful and colourful aquarium community. But always watch your betta’s attitude when introducing new companions, since each has its own personality
