Among fans of home aquariums, it has long been believed that aquarium goldfish are the least whimsical breed that does not require additional care and maintenance, as well as special experience and skills of an aquarist. Is this really true? Yes, partly such an opinion has a place to be. Indeed, all that is necessary for the successful maintenance of goldfish is proper care, namely: moderate occupancy of the aquarium, a spacious and voluminous aquarium, abundant filtration and regular cleaning, including changing the water. As you know, keeping and caring for fish includes three priority components: arranging an aquarium, feeding, cleaning and preventing infections and diseases. Therefore, we will briefly tell you about each of these components regarding the content of goldfish at home.
Let's start with arranging the aquarium itself. Aquarium goldfish are great lovers of sorting out all the pebbles and grains of sand, so we advise you to choose the largest soil, or alternatively very finely chopped options, as the fish can swallow pebbles, or (even worse) it gets stuck in her mouth. In this case, you will have to save the poor thing with a match or tweezers. As mentioned above, one of the main conditions is the filtration of water. This is due to the fact that goldfish are distinguished by an increased level of contamination of the aquarium, which is associated with an excess of waste from their digestion and the habit of constantly digging the soil. Therefore, you should install a powerful filter with a number of cleaning sections (it is desirable to have three, or even four cleaning blocks with a sponge, small and large particles). As for the water temperature in the aquarium, the gold ones are not particularly picky in this regard, but the most comfortable temperature for them will be about 21-24 degrees, so the heater in the aquarium will also not be superfluous. An additional compressor installation is desirable since aquarium goldfish love oxygenated water. Of course, aeration from the filter installed in the aquarium may be enough. It all depends on the density of the population of the aquarium and the behavior of your pets. If you see that the fish begin to swim on the surface, swallowing air, this is a clear sign of a lack of oxygen.
As for plants, the widespread opinion of aquarists that they are not necessary is extremely wrong! Plants are needed and important to maintain the ecological balance in the aquarium, in addition, they are an additional source of oxygen. There is a problem with goldfish that they are happy to eat all aquarium plants. Therefore, we advise you to purchase more stringent algae, such as cryptocorynes, anubias, lemongrass, and so on. Fish can, sorting out the soil, tear plants, so that they will be floating on the surface. To avoid this, we advise you to bury the roots of algae in larger pebbles or shells.
As for the design and structure of the aquarium itself, the classic rectangular shape is preferable for goldfish. Such an aquarium is much easier to clean, and the fish feel more comfortable in it than in rounded counterparts. We recommend that you do not purchase too deep aquariums, as this will impede access to enough light, slow down plant growth and can cause various diseases in fish.
Thus, as you can see for yourself, aquarium goldfish are really quite unpretentious in content. Perhaps this is precisely why aquarists have remained favorites for decades in a row.
