Many color and tail pattern varieties exist. They generally need a ratio of 1 male to 2 females or more. All guppies and mollies are hardy fish that tolerate lower oxygen levels and temperatures than most aquarium fish, give birth to live young, and readily breed in home tanks. [58] can live in full sea water [59] 66°F - 84°F (19°C - 29°C ...
Freshwater fish are fish species that spend some or all of their lives in bodies of fresh water such as rivers, lakes and inland wetlands, where the salinity is less than 1.05%. These environments differ from marine habitats in many ways, especially the difference in levels of osmolarity. To survive in fresh water, fish need a range of ...
The alligator gar (Atractosteus spatula) is a euryhaline ray-finned fish in the clade Ginglymodi of the infraclass Holostei / hoʊˈlɒstiaɪ /, being most closely related to the bowfins. It is the largest species in the gar family (Lepisosteidae), and is among the largest freshwater fish in North America. The fossil record traces its group's ...
Bamboo Shrimp need stable water conditions, and they do best in well-established aquariums, like one of the best tropical fish tanks, that have lots of plants and places to hide. 16. Mystery Snails
The swim bladder is an internal gas-filled organ that contributes to the ability of a fish to control its buoyancy, and thus to stay at the current water depth without having to waste energy in swimming. [1] A fish with swim bladder disorder can float nose down tail up, or can float to the top or sink to the bottom of the aquarium.
The Anguillidae are a family of ray-finned fish that contains the freshwater eels.Except from the genus Neoanguilla, with the only known species Neoanguilla nepalensis from Nepal, [5] all the extant species and six subspecies in this family are in the genus Anguilla, and are elongated fish of snake-like bodies, with long dorsal, caudal and anal fins forming a continuous fringe.
An aquatic ecosystem is an ecosystem found in and around a body of water, in contrast to land-based terrestrial ecosystems. Aquatic ecosystems contain communities of organisms — aquatic life —that are dependent on each other and on their environment. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. [1]
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ that contributes to the ability of many bony fish (but not cartilaginous fish [1]) to control their buoyancy, and thus to stay at their current water depth without having to expend energy in swimming. [2] Also, the dorsal position of the swim bladder means ...
