While the Betta splendens we see in pet stores are the result of selective breeding and are not found in the wild, there are several wild species of Betta fish.
Here are some examples:
* Betta splendens: This is the species that has been domesticated and bred into the beautiful, colorful bettas we see in stores. They are native to Southeast Asia, specifically Thailand, Malaysia, and Cambodia.
* Betta imbellis: Also known as the "dwarf betta," this species is smaller and less aggressive than the common betta. They are found in Thailand, Malaysia, and Indonesia.
* Betta smaragdina: This species is known for its bright green coloration and is found in Malaysia and Indonesia.
* Betta macrostoma: This species is a unique, large-mouthed betta with a distinctive "beak" that is found in Indonesia.
Wild bettas are generally more subdued in coloration than their domesticated counterparts. They often blend in with their surroundings to avoid predators. They also have different fin shapes and sizes than the long, flowing fins of domesticated bettas.
It's important to note that wild bettas are protected by international conservation laws and it is illegal to collect them from their natural habitats.
If you are interested in keeping a wild betta, it is best to purchase one from a reputable breeder who has responsibly sourced their fish.
