The Betta fish is a popular pet among Singaporeans.

They are beautiful to look at and can be categorised based on their pattern, colour or tail type.

In this article, we’ll be differentiating between 13 different types of Betta fish by their tail type.

Here’s a quick video on some of the Bettas we’ll be talking about:
