The bigger the tank, the less crowded it will be.

If you’re late to change the water for whatever reason, your goldfish can quickly become sick. With a 5-gallon tank, you’ll probably have to change the water every day, taking out half of the water per change depending on how many goldfish you have (and how poor water quality is). That’s why you won’t have to do as many routine water changes (or take out more water per change) to keep conditions healthy in a large aquarium. Because larger goldfish tanks have more water mass, the quality of the water decreases slower. When you change the water, you’re bringing the water quality back up to its original state. So every day that you let your goldfish tank sit, the water quality is getting worse and worse. More waste than most other fish species because of their heavy bodies. And if you’re doing a routine water change (small tanks require more frequent changes), your goldfish can go into shock if you aren’t careful to keep the newly added water the same temperature as the tank.

If someone happens to leave the window open or the power fails and cold air flows into the room, the quick temperature change will cause your goldfish serious stress. The water will take on whatever temperature the room is, heating up or cooling down much faster than a larger goldfish tank with more water mass (more water allows for slower temperature changes). A small aquarium just can’t hold enough water mass. Goldfish prefer water that maintains a constant temperature. Water changes can be very stressful in a small goldfish tank.Sadly, many goldfish never live long enough to even grow the 8 inches, 10 inches, or even 20 inches long their body was destined to be. In such an environment, goldfish usually don’t last any more than a couple of years. But growth will become stunted, and your goldfish won’t be able to develop properly. In a small 5-gallon aquarium, your goldfish will still grow.

Goldfish bowls are especially harmful because bowls usually have a very tiny surface area with no room for a filtration system. If your tank doesn’t have a lot of space with a wide surface area, you may find your goldfish gasping for breath near the water line. And because they’re so heavy, they’ll need even more oxygen. Before you know it, your goldfish are quadruple the weight they were previously. But as your goldfish grow (and grow quickly), so does their body.

Take a look at my guide on common goldfish types. If you’re keeping slim-bodied goldfish (like commons, comets, or shubunkins), you’ll need even more space – 30 gallons for each additional fish.

In addition to those 20 gallons, you’ll need to add 10 gallons (40 liters) of water for each additional goldfish you buy (if they’re fancy). No matter which way you look at it, a small aquarium equates to much more work, frequent water changes, and stressed out goldfish. And it’s much easier to keep the water crystal clear in a large goldfish tank. Assuming the aquarium is properly maintained, of course. But on the flip side, your goldfish won’t have to breathe through murky water. Depending on how many goldfish you plan to keep, chances are you’ll want a tank much, much larger.
