A filtration system must be installed in the fish tank to maintain the water quality. It is also necessary to install an oxygen pump so that the fish can breathe better.
The choice of light is one of the important skills for keeping goldfish. After the fish enters the tank, put the fish tank in a place with sunlight1~ 2 hours.

The correct feeding method is the key skill of keeping goldfish. To know what goldfish eat, although goldfish are not picky about food, don't buy inferior gold feed.
