Have you ever wondered why different fish need different temperature? And what is the impact on them of the discrepancy? And how they are sensitive to changes? Quick changes in temperature aquarium fish suffer badly, this is one reason, from which newly purchased fish die. To fish accustomed, they need to acclimatize.
Simply put, the higher the water temperature, the faster fish grow, but also age faster. We have collected some of the frequent questions about the temperature for aquarium fish and tried to answer them in an accessible form.
Yes, their body temperature depends on the ambient temperature. Only a few fish, for example, some catfishes, can modify body temperature, and even sharks maintain a body temperature several degrees higher than the temperature of the water.
This means that the water temperature directly affects fish?
Water temperature affects the rate of physiological processes in the body of the fish. For example, in winter, the fish of our ponds are inactive, because the metabolism drops significantly in cold water.
At high temperatures, the water holds fewer dissolved oxygen, and fish is very important. That is why in the summer we often see how the fish rise to the surface and breathing hard.

The aquarium except marine fish are also produced and corals called reef marine aquarium. Fast-growing corals – usually of the genus Montipora, Acropora, Pocillopora and grow in the aquarium polyp for polyp until until grows a micro-reef.
Light for corals
The word “micro-reef” very often means just a small marine reef aquarium. Coral planting in artificial conditions requires intense lighting, which is rather expensive. Therefore, the smaller the size of aquarium, the less need for coverage, the cheaper it costs.
The need for intensive lighting because the light having the wavelength required for photosynthesis, passing through the water, fades with increasing depth. For illumination with a sufficient intensity of a small light bulb aquarium requires lower power than for lighting large. Besides that they consume less electricity they are also cheaper. Another their advantage is that they are less likely to heat the water. When the aquarium light should know that excessive light is as harmful to corals as weak.
Sea current in the aquarium
A saltwater aquarium requires water circulation. Motion credif places natural growth of coral reefs is very strong. Currents, tides provide a powerful turbulent motion of sea water, which cleanses the mucus from corals, sediments and rock fragments. At the same time it provides the coral with nutrients and oxygen. Therefore, the circulation of water in marine aquariums is essential. Unfortunately, you know it’s not all aquarists. Continue reading
There are freshwater and marine fish. How do they live in the water? They breathe the oxygen dissolved in it.
Every time you open your mouth, the fish absorbs the water. The oxygen dissolved in the water absorbed inside the body of the fish straight into the bloodstream. The wastewater is then discharged through the gills, usually located on the sides of the fish’s body, behind the head.
Mudskipper is a fish with very interesting habits. There are jumpers in the Eastern Atlantic, Indian and West Pacific ocean. It lives most often in the quiet bays near river mouths. This remarkable fish that at low tide remains on land and, using fins and a special breast suction Cup, can climb trees to a height of more human growth: here it preys on insects.
In fresh water rivers and lakes inhabited by many species of fish. Freshwater fish feed on different food. Some eat algae, other aquatic insects and mollusks. Some fish eat other fish; they are real predators.
In certain types of freshwater fish are found only in one river or lake, others dwell in many places. Sometimes fish eggs is transferred to a new place, glued to the feet of waterfowl, and sometimes fish can move people. Some fish themselves swim in other rivers. When the salmon is four years old, he leaves the river and goes to sea.Having lived in the sea and two more years, he returns to lay her eggs. Many salmon return to their native river, but some moved to other rivers. Continue reading
