To observe the rules for caring for the aquarium, it is necessary. After all, without your own ecosystem, your underwater world cannot exist. Since this system is very shaky, then try to interfere with the life of your aquarium as accurately as possible. If you bring new fish, let them go through the adaptation period, because not all fish suit each other in cohabitation. Usually you should immediately ask in the store if your fish is suitable for your existing friends. There they will be able to advise you whether this or that type of fish should be taken.
