People keep tropical fish for two main reasons: they're easy to care for and they're very attractive; they come in almost any color you can imagine. However, if you want to keep them with other species, you should be careful to avoid injuries or deaths.
1. Glass Catfish: Originating in Thailand, Java, Sumatra, Malaysia, Borneo, and Indonesia. Also known as the Cathead Crystal Fish, it is very beautiful. Its most distinctive feature is that its body is transparent, with its skeleton clearly visible, and its internal organs make up less than 5% of its total body size.
2. Kissing Gouramis: Also known as kissing fish, kissing gouramis, peach blossom fish, kissing mouth fish, fragrant kissing fish, kissing fighting fish, etc., they belong to the order Perciformes, family Perciformes, and genus Gastrodon in taxonomy. They are famous for their habit of "kissing" each other. Kissing gouramis are generally 20-30 cm in length. Their bodies are oblong. They have large heads and large mouths, especially thick and large lips with fine serrations.
3. Blind Fish: Native to Mexico. It is a very beautiful ornamental fish, about 8 cm in length, with bright silver scales and cream-colored fins.
4. Zebra Danio: Also known as the blue-striped fish or spotted fish. Native to India and Bangladesh. The zebra danio has a spindle-shaped body, about 5 cm long, with a rounded chest and abdomen and a laterally compressed tail. Its body is predominantly yellow, with an olive-green back. Multiple dark blue longitudinal stripes run from its back to its abdomen and anal fin, extending to its tail fin, giving it a zebra-like appearance, hence its name.
In addition, there are the common guppies (details), which are very similar to peacocks because of their large, long tails, graceful bodies, and relatively easy-to-raise and moderately priced fish. Therefore, many people keep guppies.
