Contrary to certain beliefs, Goldfish aren’t schooling fish that need the company of their own kind to thrive. They’re quite social and often enjoy the presence of others, but they don’t necessitate a companion to survive or be happy.
However, if you choose to keep more than one Goldfish, ensure sufficient space in the tank to cater to both needs. Overcrowding can elevate stress and potentially instigate harmful conditions. So, before setting up your new tank or considering adding new fish to your existing tank, think of your current tank conditions.
