Around here we have talked a lot about classes and species de fish that exist. As you well know, there is a great variety all over the planet, which means that we can find everything. Of course, each of them is more surprising than the last, so studying them is not a bad idea.
However, we would like to ask you a question: is it dangerous to mix these species? If we had to say it in a few words, the truth is that we do. Each of the classes has its own characteristics and needs, so putting them all together would be a danger that we must avoid.
Let's say it with other words, and an example. Let's imagine that a fish that resides in the sea, we put it in another territory. This means that you would have to adapt. But not all types succeed, so it could cause more than one problem. The solution, of course, is to avoid all of these cambios.
The most advisable thing is to take into account the needs and movements of different types de peces, which means that, for some, what is normal is not the same for others, so changes and modifications could occur that would be bad for them. No, it is not a good idea to mix classes de peces.
Let's say it clearly. Mix different classes or species de peces not good. More than anything, because of their different needs. So, if that idea occurs to you, it is not recommended that you carry it out. Of course, there are different associations that have done this, but it is always about Professionals.
Finally, if you want to have some type of fish in your house, and you do not know if you can have it, our recommendation is that you consult it in a pet store, where you can help with all the doubts you have. When in doubt, you already know that all help is good.
