An aquarium structure includes a body, the body includes a first water tank and a second water tank, and a bottom surface of the first water tank and the second water tank, and a flow port is formed between the first water tank and the second water tank； the first water tank has an upward direction The open slot is open and opposite to the bottom surface, the body is only communicated with the outside by the open slot of the first water tank, and the shortest distance from the open slot to the bottom surface of the first water tank is a first longitudinal dimension； the second sink has a top surface and The second water tank is closed and communicates with the first water tank only by the flow port. The shortest distance from the top surface to the bottom surface of the second water tank is a second longitudinal dimension； the first longitudinal dimension is smaller than the second longitudinal dimension. Thus, it constitutes an aquarium different from the conventional square cylinder and circular cylinder, and has two aquariums of the same type of sinks.一種水族箱結構，包括一本體，本體包括有第一水槽與第二水槽，以及位於第一水槽與第二水槽的底面，第一水槽與第二水槽之間有流通口；第一水槽具有向上開通的開放槽口並相對底面，本體僅由第一水槽的開放槽口與外界相通，第一水槽的開放槽口至底面兩者最短距離為第一縱向尺寸；第二水槽具有一頂面且相對底面，第二水槽為封閉狀僅由流通口與該第一水槽相連通，第二水槽的頂面至底面兩者最短距離為第二縱向尺寸；第一縱向尺寸小於第二縱向尺寸。如此構成一種不同於以往方缸、圓缸造型的水族箱，並具有兩個彼此相通的水槽型態的水族箱。
