Top 3 Glass Picks:
1. Hygger Horizon 8-gallon LED Glass Aquarium Kit
If you’re in the market for a larger bowl for your goldfish, the Hygger Horizon 8-gallon is a great option. This kit comes with a filter, LED lighting, and even faux rock décor. It does not have a lid but the LED light sits a couple of inches above the top of the tank. Due to the size of this kit, your goldfish may not need to be upgraded for a period of time as long as routine water changes are performed. The curved-front glass is sleek and the tank itself is long and narrow, which is the preferred shape of active goldfish.
2. Glass Goldfish Bowl by WGVI
This is a beautiful, hand-crafted bowl available in three sizes with openings from 4-6 inches, making it small enough to help keep goldfish from jumping out but large enough to allow for adequate cleaning. It is a sturdy weight and the glass is almost a quarter of an inch thick. The 10-inch bowl can hold just over two gallons of water. This bowl may have bubbles within the glass due to the handmade nature of the product, which adds to its charm.
3. Glass Fishbowl on Driftwood by Cohasset Gifts
This bowl option is a true stunner. It is crafted from handblown glass and real wood grown in Indonesia. Each bowl is unique in size and shape, but they hold anywhere from around one gallon to over four gallons of water depending on the inch size purchased. These bowls have approximately a 4-inch mouth. Due to the interior texturing of these bowls, they are a lovely option for plants and the unique design creates enrichment in a nano environment.
Top 2 Plastic Picks:
1. Koller Products 1-gallon fishbowl with LED lighting
The Koller plastic fishbowl is a great option if you’re in the market for a smaller bowl. This may need to be upgraded to a larger bowl as the fish grows. This bowl has the clarity of glass without the weight and it’s shatterproof. It has a lid with LED lighting featuring seven different colors and a timer. The lid also has openings that allow for oxygen transfer, ensuring fish are able to breathe.
2. Koller Products 2-gallon hex fishbowl
This is another lightweight, shatterproof option for small goldfish. Since it only holds two gallons, it may need to be upgraded as the fish grows. This bowl features a cool hex shape, making it a great option for a unique look. It has a small enough opening to reduce the risk of fish jumping out, but it is large enough to make it accessible for cleaning.
Top 2 Acrylic Picks:
1. biOrb Halo Aquarium
This futuristic-looking fishbowl features a hidden waterline, five-stage filtration, and multi-colored lighting. The lights are remote-controlled and have different brightness levels. It also has a lid with magnetic catch, making for easy access when needed and keeping other curious pets out the rest of the time.
2. Outgeek Bubble Wall Hanging Bowl
For small fish, this is a beautiful bowl option. This also works well in spaces without surface space available for a fishbowl. The hanging bowl will require frequent water changes for maximum fish health. This bowl works well as a planter and a shared space with a plant can help oxygenate the water for the fish.
Tips for Choosing The Best Goldfish Bowl
There are 3 main things to consider:
In general, the bigger the bowl – the better.
More water volume helps dilute the waste byproducts…
… and increases surface area for oxygen exchange.
Larger bowls allow more space to grow aquatic plants, which are INCREDIBLE for keeping the water safe for goldfish.
More plants = less work.
And they can support more fish.
From an aesthetic perspective:
Larger bowls have less distortion for viewing your fish than smaller bowls.

2. Surface Area
This isn’t as much of an issue if you have some kind of electric filter or airstone creating gas exchange.
Bowls that have a larger surface area (i.e. wider opening) for the water can support aquatic life better – especially when plants are being used as the only filter.
Thanks to better oxygen exchange.
You can also achieve a larger surface area by not filling the bowl up all the way to the top (if using a typical bubble style bowl).
You lose water volume which results in less swimming space for the fish, so starting out with a larger bowl can make up for this.
Sometimes the more unusual styles of bowls can actually afford great surface area for the size (even glass trifle or mixing bowls).
If using glass aquaria, thicker glass will be more durable.
Trust me, you will want this.
Glass that is too thin can burst without warning, harming your fish and your house and leaving a huge mess.
The bigger the bowl, the more important it is that the glass is durable.
Plastic or Glass?
Plastic containers are definitely the cheapest.
I even have one myself…
… but honestly prefer glass given the choice.
Plastic can leach chemicals into the water if heated which can harm aquatic life.
(The stuff used to make plastics can include glass fibers, mineral, flame retardants, colorants, release, silicone, formaldehyde and more – yikes! (source))
So while glass can be more pricey, it gives you peace of mind for the long-term health of your fish, especially if you plan on adding a heater.
The investment is well worth it.
A goldfish bowl is not only supposed to be an ornamental accent to your living area…
It’s perhaps the most fascinating and educational object you can have in your home!
