Goldfish are a cold water fish, so it need not be kept in a heated fish tank. They can be kept in a fishbowl. Goldfish looks attractive because of its variety of colors. Keeping it in a bowl simply adds on to its look. It makes a wonderful and cute gift to present someone special.
Your Goldfish kept in the bowl will stay healthy and active if it gets proper filtration. You can use the Sponge filter or the under gravel filter. Among the two under gravel filter is a better choice as it does not take up much space.
You need to clean your goldfish bowl weekly. To do so you first need to pour water from your Goldfish bowl to a smaller clean bowl and transfer your goldfish into that new bowl. You can use a small net to catch your goldfish. Once done, empty the water from the goldfish bowl and clean it properly with hot water. Do not use any detergent. There are chemical cleaners available. Finally rinse it with tap water.
Now that the bowl is cleaned, fill it with fresh water and wait till the water comes to room temperature. Then transfer your Goldfish back into the original bowl. Wow! Doesn’t it look all new and classy again?
