IZUMI Table (Round)
This patented round Bird’s Eye Aquarium is designed with a crystal clear top view. Once the pump is on, the cloudiness of the glass top plate caused by condensation will be gone, creating a clear top view. Thanks to its elegant curves creating different atmospheres, Izumi has become our hot-selling product for long. Customisable.
Crystal Clear Top View
Bird’s Eye Aquarium is an aquarium table
developed, designed and manufactured in Japan,
with a crystal clear view from above
thanks to the close contact between the water surface and the glass top plate.
This design has patents granted from different countries around the world.
Excellent Filtration Capacity
With the entire dead space under the table
completely turned into a filter space with high capacity ratio,
and water treatment close to natural purification,
a healthy environment is maintained for the water creatures
and a stress-free aquarium for fish keepers.
Upon setting up the aquarium,
the water quality should probably become stable in about a month, subject to the aquarium contents.
Even if you are keeping marine fish
and there is no large-scale equipment installed,
water can simply be changed once every three to six months, as carefree as a pet can be.
* Topping off the aquarium is required.
* Feeding on a daily basis is necessary, and automatic feeders can also serve the purpose.
All-In-One
Aquarium accessories like pumps and LEDs
and their wiring are all housed inside the table.
As they are concealed by premium materials,
the exterior can be kept neat and tidy.
Tables are often go unnoticed
even when they are in the centre of a room,
but they are now transformed into spectacular home decor
to stand out in the space.
It brings you and your family immersive experiences in a fascinating aqua world.
With this unqiue auqarium, we can enjoy the same view of a bird flying in the sky.
It is therefore named as Bird’s Eye Aquarium.

Frequently Asked Question about Bird's Eye Aquarium
Table aquarium is not something new. How do you differentiate your product with others?
Bird’s Eye Aquarium appears to be sealed. Will fish be deficient in oxygen?
The viewing tank that can be seen clearly from the top appears to be sealed, but when water flows to the filter space, it will come into contact with the air, so oxygen is sufficiently supplied.
Fish get stressed easily. Is their health condition okay?
Where should I install Bird's Eye Aquarium?
It is emphasized that the filtration capacity is high. Does it mean that maintenance is not needed?
What filter media should I use?
Where should I put the filter media?
Please tell me how to maintain the tank regularly.
Please tell me how to feed fish.
There are two ways. You can either lift the top glass plate and feed directly into the viewing tank or open the lid of the filter space and feed in a way that the water pump will suck and send the fish food to the viewing tank. If you choose to use the method of feeding directly to the viewing tank, depending on the fish species, fish may pop out, so you should stop the water pump before lifting up the top glass plate. Also, if you drop the fish food near the overflow pipe, it may fall into the filter space together with the backflowing water, so you should immerse it into the water before releasing it from your hand or dropping it to a place further away. If you use the method of feeding in the filter space, open the lid of the compartment where the water pump is located and put the fish food in a way that it can be sucked and sent to the viewing tank via the piping system. As had in an ordinary overflow aquarium, fish food will be spread inside the tank while fish could be fed evenly, so it is a good method. Besides, if auto feeder is added as an option, we will supply you with another lid such that when an auto feeder is attached on it, fish food can be dropped onto the water automatically. Feeding becomes more convenient. However, if the fish food is not sucked by the water pump, it will remain in the filter space and become spoiled, so please make sure that fish food is not left in the filter space during maintenance.
Please tell me how to refill water.
Is it okay if I do not refill water?
Is it okay if I do not close the lid of the filter space?
What should I do when my fish died?
I'm considering introducing Bird's Eye Aquarium to my restaurant, but is it fragile?
I cannot see clearly from above. Is there any problem?
- The top glass plate is not in the right position. Please check.
- The output of the water pump may be at the "weak" position. Please adjust the lever and see if the condition is improved. Maybe there are some problems with the water pump like it is getting weaker due to deterioration or sand is being caught inside. In this case, please follow the instruction manual of the water pump for troubleshooting.
- The pipes may be disconnected. Please check and connect them firmly.
- The floor may not be level. A slight tolerance of horizontal level is allowed, but whenever necessary, use spacers to make fine adjustment.
