I’ve had goldfish in the past but due to a filter malfunction whilst I was on holiday and some bad advice I was given they sadly passed away. However, it has been a year since them and I think I’m ready to get a new pet. Fish would be ideal as they don’t smell much, and are relatively small (compared to a dog or cat) so require less space. Although, I really don’t know what type of fish to get. I wanted a betta fish for about 6 months and did loads of research about them, but my dad doesn’t want me to have a tropical fish as he doesn’t want a heater in the house. Therefore, I was wondering: What are the best cold water fish for beginners?
