Bird's Eye Aquarium

Fish Tank Allowing Aquarium Fish To Be Viewed Clearly From The Top

Panel Saw

Fish cannot be viewed clearly
from the top of a traditional fish tank
due to the natural or mechanical wave on the water surface.
Also, the water condensed on the underneath surface of the top glass plate
resulting from evaporation or splash of water in the viewing tank
is also a source of unclear top view of a fish tank.

Bird’s Eye Aquarium adopts the method that receives water
overflown from the viewing tank to the gutter surrounding it.
Placing a glass plate on top removes the air layer
between the top glass plate and the water surface,
resulting in a close contact between the two media.
The water surface becomes smooth,
leading to a prolong crystal clear top view of the inhabitants inside.
