Which one is better for beginners starting their first aquarium?

Bettas are one of the brightest freshwater fish with long and bright fins. They can be found in colours such as blue, red, white, purple, and even metallic colours. At the same time, guppies are much smaller and more colourful. Male guppies have bright tails with various patterns, which can be either spotted, striped or mosaic. In case you are interested in having a solitary pet in your aquarium, a Betta is a perfect choice. If you prefer a lot of colourful fish that swim all together, then Guppies are for you.
