Siamese Fighting Fish, commonly and incorrectly referred to as Betta fish (this is just a sub-species), inhabit Thai rice paddies in the wild and have become popular pets. They have aggressive behavior (thus the name) and are often hostile towards one another, especially between two males. Males are bigger than females and they have longer fins that almost look like feathers. One unique characteristic of Siamese Fighting Fish are the bubble nests that the male fish make when they breed. They gulp in air with their mouths from the surface, wrap it in a bubble of saliva, and spit the bubbles out continuously until a nest forms. When the female is ready, she emits the eggs and they float up to the bubble nest where they will eventually hatch.

Macropodinae is a subfamily of marsupials in the family Macropodidae, which includes the kangaroos, wallabies, and related species. The subfamily includes about ten genera and at least 51 species. It includes all living members of the Macropodidae except for the banded hare-wallaby (Lagostrophus fasciatus), the only surviving member of the subfamily Lagostrophinae.
Macropodinae includes the following living genera:
- Dendrolagus (tree-kangaroos)(12 species)
- Dorcopsis (greater dorcopsises)(4 species)
- Dorcopsulus (lesser dorcopsises)(2 species)
- Lagorchestes (hare-wallabies)(4 species, 2 extant)
- Macropus (kangaroos, wallaroos, and wallabies))(16 species, 13 extant)
- Onychogalea (nail-tail wallabies))(3 species, 2 extant)
- Petrogale (rock-wallabies)(16 species)
- Setonix (quokka)
- Thylogale (pademelons)(7 species)
- Wallabia (swamp wallaby)
Different common names are used for macropodines, including "wallaby" and "kangaroo", with the distinction sometimes based exclusively on size. In addition to the well-known kangaroos, the subfamily also includes other specialized groups, such as the arboreal tree-kangaroos (Dendrolagus), which have body masses between 4 and 13 kg, and a relatively long prehensile tail.
