An important aspect of goldfish care is to observe them regularly to ensure that they are healthy. This will save your efforts and time to make trips to a pet store or your vet.
Like human beings, fish require oxygen to live. They release carbon dioxide. At the same time, the plants in your aquarium will take in carbon dioxide and they will release oxygen. So if you have many plants in your aquarium, they will help goldfish to remain healthy.

So you need to keep the aquarium clean, you should feed the fish healthy food at appropriate times maintain normal temperatures in the aquarium and change the water regularly.
