The water temperature for aquarium fish

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.

Fish cold-blooded?

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.

How to grow coral reef in a saltwater aquarium

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

Corals and fish of the red sea

There are on our planet, the sea of extraordinary beauty, attracting millions of tourists from all over the world for its clear water, beautiful corals and diverse fishes. It comes to the Red sea. This is one of the most beautiful places of our planet.

Why do they call it? No exact answer. Someone thinks that it got its name due to algae that in some months, the sea change colour from azure blue to red. And some prefer a more interesting explanation. According to the Bible, Moses led the Jews from Egypt to Israel through the Red sea. When they approached the shore – the water parted and exposing the bottom. It consisted entirely of canyons, cliffs and hollows. The path was very rugged and a lot of Jews died, bleeding to death. That’s why it was called the Red sea.

The red sea is a Gulf of the Indian ocean. It is situated in the deep depression, formed millions of years ago between the Arabian Peninsula and Africa. An area of almost 500 thousand square kilometers, with more than two thirds of the sea is located in tropical zone. The average water depth from 500 m to 1 km in the middle part of the sea is crack, as if dissecting it into two parts. There is a depth of 2.5 to 3 km. makes it different from other seas of our planetat that the Red sea is not no river flows. The Suez canal in the Northern part of the sea – the work of human hands, it is rather narrow, so the natural circulation of water occurs only in the southern part of the sea through the Bab-El-Mandeb.

This natural isolation has led to the fact that in the Red sea the most clear water. Usually the rivers carry their waters in the sea sand, debris and dirty water. But in this sea water is so clear that you can easily see the incredible beauty and diversity of “underwater life” of the red sea.

The absence of influent rivers has also led to the fact that sea has the most salty water among all seas on our planet. The salt concentration here is that to drown is almost impossible. It is well suited for those who decided to learn to swim and likes to swim far away (fatigue less than in the other seas). Continue reading
