Natural aquarium: big and small fish - whom to choose?
Before each aquarist, the question arises: which fish to choose in a natural aquarium - large or small? You choose, however, there are features that are worth considering.
There is a fundamental difference in the content of large and small fish in a natural aquarium.
Large fish are most often predators, and small ones are mainly herbivores. Herbivorous fish eat 3 times a day (ideally) or, in extreme cases, 2 times a day. Adult predatory fish is fed 1 time in 2 to 3 days, but the feeding process takes about 15 minutes (throw a piece of food, wait until it is eaten, and “deliver” the next - and so until the fish is full).
If the big fish is properly fed, the water is always clean and the aquarium looks beautiful, because even if there are leftovers, they are processed by the filter for two days, and the biological balance of the aquarium is leveled. In addition, as a rule, in addition to large fish, they contain several more small ones (for example, some types of catfish) that eat up what the “giant” did not eat.
Another difference in the content of large fish in a natural aquarium is that they are noticeable. You see how they swim, how they behave. And if she gets sick, then it will take 1.5 - 2 months before she dies. You will have time to diagnose the disease and cure the pet. And if she does die, you will definitely notice it. But if you do not suddenly notice, the damage will be enormous: it will begin to decompose, the water will become cloudy, and all other fish will also die.
Large fish are more unpretentious to the conditions of detention (they need to be fed less often and water can be changed less often without harming the health of the aquarium inhabitants).
If you choose small fish for a natural aquarium, then you will have to change the water more often, it will be harder to notice that the fish are sick, and if you missed the onset of the disease, then after 3 to 4 days the fish may die, and you may not even see it.
Small fish usually cost less than large fish, but owners of small fish go to the pet store more often (buy new plants, fertilizers, replenish the “collective” of pets, etc.)
In one natural aquarium, many different types of small fish can live, and in the case of the "giants" you can place in the aquarium, as a rule, no more than 3-5 species of inhabitants.
In the aquarium, where small fish live, the main attention is paid to the habitat, and a large one in itself can be the main decoration of your underwater kingdom.
Big fish can get bored pretty quickly: you are always observing the same thing, and in the case of small fish, there is more space for creativity and the picture is constantly changing.
An aquarium for large fish is something like a container for overexposure, a kind of cage for a pet. And small fish in an aquarium of the same volume can create a full-fledged underwater world, an ecosystem.
