Tips on the number of fish in the aquarium
A huge number of diseases in fish appear due to low water quality, so the main thing for you is to maintain the water in the aquarium in good condition.

The most common mistake that people make when settling the aquarium is the calculation that the fish sold in stores are adults. The stores sell fry, and when they grow to full size, it turns out a very overcrowded aquarium or worse-an aquarium in which the fish can not normally accommodate. To avoid this, you always need to find out detailed information about the fish that you plan to purchase.
Be sure to clarify the Latin name of the fish to prevent confusion in common names, which can vary significantly.

As a General rule, 4.5 liters of water for every 2.5 cm of fish length
For goldfish, the more space – the better! An aquarium of 115 liters will be enough for 1 decorative goldfish. For each additional individual, an additional 38 liters of water will be required. Goldfish grow to at least 15 cm, so they need a lot of space to swim. The smallest length of the aquarium suitable for adult goldfish is 90 cm. Young individuals can be easily kept in a smaller aquarium, but they must be moved to a large aquarium or pond as soon as they grow up.
The General rule is 4.5 liters of water for every 2.5 cm length of the fish, with an increase in the quality of water filtration, you can gradually move to 4.5 liters for every 5 cm length.
To begin with, until the fish grow up, you should proceed at the rate of 4.5 liters for every 2.5 cm. it is Necessary to monitor the quality of water and monitor how the environment behaves with the current number of fish, you should pay special attention to how quickly the concentration of nitrate (NO3) will reach 50 parts per million, as well as the number of water changes and the volume of water per shift.

Some species of fish living in ponds can reach very large sizes, so you should be very careful when choosing – if you have a small pond, we advise you to stop at goldfish.
