Also, the tank mates must be able to live off a diet that is catered towards goldfish. For many fish on our list, this environment is on the lower end of their comfortable temperature range.

Goldfish mainly prefer cooler temperatures from 50-70☏ and can live at room temperature without a heater.

Goldfish are beautiful, much-beloved creatures in the fish keeping hobby, but sometimes it can be nice to add a little variety to their aquariums.
