Fishkeeping

The danionins are a group of small, slender "minnow-type" freshwater fish nestled in the family Danionidae of the suborder Cyprinoidei. Species of this group are in the genera clades Danio and Devario (which also includes Chela, Laubuka, Microdevario, and Microrasbora genera), based on the latest phylo-genetic research by Fang et al in 2009. They are primarily native to the fresh waters of South and Southeast Asia, with fewer species in Africa. Many species are brightly coloured and are available as aquarium fish worldwide. Fishes of the Danio clade tend to have horizontal striping, rows of sp

Dermogenys is a genus of viviparous halfbeaks. They are widely distributed in fresh and brackish water in South and Southeast Asia, ranging from India to the Philippines and Greater Sundas. They are all viviparous, producing small clutches of up to 30 fry that closely resemble the adults, except they are much smaller, around in length. Adults are typically around in length, with females being slightly larger than males. Males tend to be more brightly coloured and are well known for being aggressive towards one another. The wrestling halfbeak, D. pusilla, is widely used in Asia as fighting anim

Hemirhamphodon is a genus of viviparous halfbeak fish. Most recognized species are endemic to lowland forest streams, rivers and swamps in Borneo (often in areas with peat), but H. phaiosoma and H. pogonognathus are also found elsewhere in Southeast Asia. The largest species reaches about in length. These fish are viviparous (with the exception of oviparious H. tengah) and are sometimes kept as aquarium fish, but otherwise have no commercial value.

Aquascape designs include a number of distinct styles, including the garden-like Dutch style and the Japanese-inspired nature style. Typically, a

Nomorhamphus is a southeast Asian genus of viviparous halfbeaks from streams, rivers and lakes in Sulawesi (Indonesia) and the Philippines. They are all viviparous, producing small clutches of around a dozen fry about long at birth. Females are generally larger than the males. In the largest species, such as Nomorhamphus liemi, the females typically reach about in length, whereas the males reach about in length. Males are also more brightly coloured than the females (often having red, black, or blue patches on their fins). Compared with many other halfbeaks, the lower mandible, or beak, is rel

The wood is usually stained brown by tannins dissolved in the acidic water. Bog-wood represents the early stages in the fossilisation of wood, with further stages ultimately forming jet, lignite and coal over a period of many millions of years. Bo

An aquarist is a person who manages aquariums, either professionally or as a hobby. They typically care for aquatic animals, including fish and marine invertebrates. Some may care for aquatic mammals. Aquarists often work at public aquariums. They may also work at nature reserves, zoos, and amusement parks. Some aquarists conduct field research outdoors. In business, aquarists may work at pet stores, as

Exposition in Fisheries Museum in Hel (branch of National Maritime Museum in Gdańsk) A livewell is a water tank found on many fishing boats that is used to keep live bait and caught fish alive. It works by pumping natural water from the surrounding waterbody into the tank, as well as an air pump for water aeration. It is a standard design feature in many modern sport fishing boats and yachts, especially those used in fishing tournaments, as competitions typically weigh participants' catch only at the end of the round and
