In the aquarium internet forums very often the correct water levels and the welfare of ornamental fish are discussed. What we mean by 'animal welfare' and what are the proper water parameters. The following Article attempts to approach this problem and to offer interested aquarists help.
The element of water
the fish originate in our aquariums from various regions of the world, from the rain forests of South America and Asia, from the mountainous regions of the Andes and China, from the grave lakes of East Africa, the rice fields of India and also from areas which only cause temporary water. Just as these regions also differ in their living conditions, all have the element in which they live, the water. They have adapted to this element, they live in almost pure deionized water and acid just as in the ion-rich salty seas. Some species such as the Eel even switch between these two extremes and adhere to talk and sometimes on there.
importance of water values
Especially in the internet forums is attached to each water temper my opinion, far too much importance. pH or water hardness certainly have an impact on the fish and its physiological processes. The fish tolerate large margins particularly as regards the pH value with no problems. Major changes to the pH value, even more, the hardness of water and ingredients require a slow adaptation of the organism. For this reason, fish at the onset or reacting slowly to get used to the new water.
are sensitive as it might Eggs and larvae. On the other hand, have the larvae and juvenile fish, no strong immune system, making them more susceptible to germs.
Clean Water
seem of greater importance to me to be other factors, there are even clean water. We measure only 5 to 6 different water values with our hobby tests, one or the other maybe a few more values in the water but are much more substances dissolved, above all, we bring through feed, fertilizers and other other substances, including especially in quantity.
stocking and social aspects
addition, the socialization in our aquariums. The stocking density is much higher as in nature, which alone makes possible infection and transmission of pathogens much more frequently.
The social acceptability within species but also among different species is markedly affected by these constraints.
When we discuss optimal environmental conditions, then we need much more thinking about these issues. I know that this is much more difficult, a water value can be a few paragraphs describe a simple and better.
feed
important for our fish is a varied but balanced diet. Do not mix different types of dry food to the diversity, but the combination with frozen food and especially live food!
Conclusion
the Internet are often exaggerated the water values. Of course they have a meaning that shows alone the fact that breeding and raising tropical fish in soft acid water works better in many ways. A certain
Adaptationan of water conditions for many fish also possible.
