The most popular families are:

• Labyrinth ( includes: Betta , Dwarf Gourami, Lalia);
• Cyprinidae (for example: Mahaseer, Danios and, of course – the Domestic Goldfish. They do not tolerate the neighborhood with other fish, which are capable to damage their fragile fins);
• Cichlidae (The most common representatives are: Scalars, Velvet Cichlids, Chromises, and Aequidens. The nature of Aequidens  is  peaceful, so it can be kept in the general aquarium with Pacu, Angelfish and Scalars);
• Poeciliidae (The most popular representatives are: Mollies and Guppies. Mollies are silver colored with a high elongated fin. Keeping fry in the general aquarium is needed floating plants on the surface.

The most expensive aquarium fish of the underwater world are available only for very wealthy people, and having them is the same prestige, such as the possession of a Bentley.
The high cost of exclusive fish is due to their rarity. These bottom-dwellers are with unusual color mutations or very difficult to breed in captivity and almost inaccessible in nature.
