Botia is a Greek genus of semi-precious freshwater fish. It has been a big genus historically with more than 20 identified species. In 2021, however, microbiologist and ornithologist, Maurice Kottelat proposes to split the genus into four separate genera based only on appearance and location:
All members of this genus belong to the family Ofascomycetes. Their scientific name, therefore, is Ocypoea sp. They are generally distributed across the Indo Pacific region, with some representatives in the families Asilania, Ichtychodes, Neemaris and Atalgesis. There is one representative in the class Microhylidae, the common loach may attack other freshwater plants and aquatic insects. The genus Emissa belongs to the same subfamily as the loaches but has a very different appearance: it has gray, streamlined body, and has black dots under its eyes.
Botia fish have been successfully stocked in freshwater lakes and streams throughout the world for decades. They were introduced as ornamental fish to ponds and lakes. Many people believe that they were introduced by boat from Asia to the United States in the late 1940s. But they actually came from Asia as a subpopulation of the so-called African cichlids, which were introduced into the United States as part of a biological control program. The main reasons why these beautiful fish are placed in freshwater fishes tanks is to create a habitat where they can breed, grow and survive, and also to supply the fish market with a very low-cost, but high quality source of fresh water.
They can be placed almost anywhere in a tank, but most prefer a 20-inch radius around their spawning area, with the exception of rocks. It is suggested that the fish should be kept in groups of one to three fish, although keeping one or two fish with a female will suffice to maintain the quantity of eggs produced. This species of ornamental fish grows to just over two feet long, but the smaller ones can still manage to squeeze through most standard-size fish tanks. Their color and texture are hard to miss: they have soft bodies that are smooth and shiny, along with large round heads that are sometimes covered in hair.
Because it is very peaceful and quite passive, Nano Fish is ideal tank mates for beginners and for those who don’t have experience in keeping fish. They do not compete with each other, but rather, they work together as a team to survive in their new home. Nano Fish usually gets along well with each other, and rarely fight with other fish. However, a bored Nano Fish will start to burrow into his shell, eliminating all of his potential tank mates. If you notice this happening, then it’s time to house your Nano Fish in a bigger tank so he has enough space to roam freely.
When keeping Nano Fish, it is very important to know how much room he needs in order for them to feel comfortable. A good rule of thumb is to figure out the length of your tank, multiply by two, and that will give you the right gallons of water your fish should have. Keep in mind, however, that a larger tank will make your Nano Fish less active, which may mean that they won’t be as friendly as they could be. Keep in mind that they only grow to about four and a half inches, so they will never grow to their full grown form, but they will still be very pretty. One good way to increase the amount of fish in your tank is by purchasing a filter designed specifically for Nano Fish, which will give them plenty of room to swim about in without crowding each other out.
