Hmmm.... Do you want to compare?
Show how in the environment bettas don't really live in muddy puddles, and only end up in such situations during the dry season. Even then, when their water gets too shallow or filthy they hop out, trying to make it to a new puddle to call home!! Neither the male or females are colorful... They have natural colors, rather neutral, which obviously would help them survive. To some people they resemble "minnows" because of the shape of their bodies, and the lack of color we see in Betta Splendens.
In comparison to Betta Splendens: Commonly people assume that bettas can live in a bowl, never cleaning it for months on end - because they compare it to their wild cousins, and their environment. What people have failed to realize, is in the wild mother nature takes care of the water, while in bowls and aquariums we ARE mother nature and must care for them as such
You could add the different wild types, such as Embellis and....whatever others x.X
