Just like you would not do well when crumped up in a tiny room all your life, goldfish also cannot live in small bowls. Your goldfish will reward you by healthier and better health resulting in them living as long as they should and without always getting sick and fighting if you give them space. The bigger the better when it comes to the goldfish tank because you will actually be surprised at how much they can grow to give the room. Here is a guide for selecting the right tank size for your goldfish.
For the fancy goldfish, the general rule is 10-20 gallons for each one of them. The slim bodied ones will need around 40 gallons for the first one and additional 20 for each one more that you add. Larger tanks don’t need more work, as many people may wrongly believe, and this is because the waters in the small tank will frequently get dirty and this means more water changes. Choosing the right tank size ensures that you can keep the ammonia level in control and that you can also do enough water changes keeping up with the load of waters placed on the filter. Many people and especially the enthusiast who want to keep all of them and buy every beautiful one that they see even with the small tanks never understand that this is a life and death situation for the fish. In simple terms, the larger tank will be good for the fish and easier for you.
Unlike what many people may believe, keeping the goldfish in small tanks do not keep them from growing in the sense that you think. The undersized environment will often have poor water quality and the fish organs will grow when its size doesn’t and this will only lead to a shorter lifespan. Before you can buy the tank, therefore, you should decide on the amount of the goldfish that you want to keep. Remember to stick to the original plan and follow the stocking rule. If you have decode on the number that you want to have but the finances are not so flexible then you should consider the garage sales and the secondhand stores where you can get a decently working tank at a fair prices that will mostly come with accessories and equipment. Last but not the least, you should get the biggest tank that you can afford.
