A reef aquarium or reef tank is a marine aquarium that prominently displays live corals and other marine invertebrates as well as fish that play a role in maintaining the tropical coral reef environment. A reef aquarium requires appropriately intense lighting, turbulent water movement, and more stable water chemistry than fish-only marine ...
The temperature is nearly constant after 1500 meters depth. A thermocline (also known as the thermal layer or the metalimnion in lakes) is a distinct layer based on temperature within a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) with
Graph showing ocean temperature versus depth on the vertical axis. The graph shows several thermoclines (or thermal layers) based on seasons and latitude. The temperature at zero depth is the sea surface temperature. The ocean temperature plays a crucial role in the global climate system, ocean currents and for marine habitats.

Temperature reconstructions based on oxygen and silicon isotopes from rock samples have predicted much hotter Precambrian sea temperatures. [ 10 ] [ 11 ] These predictions suggest ocean temperatures of 55–85 °C during the period of 2,000 to 3,500 million years ago , followed by cooling to more mild temperatures of between 10-40 °C by 1,000 ...
Deep-water coral Paragorgia arborea and a Coryphaenoides fish at a depth of 1,255 m (4,117 ft) on the Davidson Seamount. The habitat of deep-water corals, also known as cold-water corals, extends to deeper, darker parts of the oceans than tropical corals, ranging from near the surface to the abyss, beyond 2,000 metres (6,600 ft) where water temperatures may be as cold as 4 °C (39 °F).
Marine aquarium temperatures should mimic the natural environment of the inhabitants and are most commonly maintained at 23 to 28 °C (73 to 82 °F). In regions where the ambient temperature is less than the desired temperature of the aquarium this generally necessitates the use of an aquarium heater.
