Fish are a great option if looking into buying a pet for the first time, and the notorious betta fish are known for being especially low-maintenance. Not only are they absolutely gorgeous with their long rainbow fins, but they're easy to own, too: keep them in a large-size, clean tank, and feed them betta-specific food pellets. Apart from that, it's just important to remember not to mix two bettas in the same tank, and be prepared to be amazed at their mesmerising beauty.
