Only if there is

The sea aquarium needs much more careful care than the "fresh pond". The inhabitants of the sea and the ocean are very demanding, so it is necessary to constantly monitor their biofluor and support it at the proper level. So, a change in water temperature even by a couple of degrees, and also not that salt concentration, will lead to the death of fish. In other words, the sea aquarium is like a gambling game with nature: the winnings are provided only if there is a lot of experience. Only painstaking care for the aquarium and its inhabitants will give you all the beauty of the sea world.
