About the relationship of the volume of the aquarium and the health of its inhabitants
No fish can "outgrow" the size of their home. After all, its maximum size laid by nature for each of the species. At the same time, it is necessary to take into account that the inhabitants of fish houses grow throughout their lives: faster at a young age, more slowly. in old age. That is, the maximum size of all types of fish is determined initially. However, observations of aquarists indicate that in a spacious aquarium, they grow faster and reach larger sizes than in a small one.
The size of the fish house can affect the growth rate, the final size and the lifespan of its inhabitants. In a small there is not enough space for movement, and its inhabitants as a result of physical inactivity can suffer from diseases associated with low mobility. In such an aquarium, it is not very convenient to maintain cleanliness, feces and food debris accumulate in it faster, which means that the parameters of water also change. The smaller the size of the fish house, the faster the level of nitrates and nitrites and other compounds, which adversely affect the health of aquatic animals, increases there. Water parameters that do not suit them, cause loss of appetite. Small fish lack microelements, nutrients, grow slower, weaken, rather die. That is why it is so important to select the residents for a small amount of indoor water.
