A tunnel-type aquarium is characterized in that a body and a plurality of holders holding the body are made of a transparent material to allow rays sending from a plurality of light emitting units which are disposed on the bottom of the holders to be transmitted to the body through the holders. The rays are further transmitted outwards through surfaces of the body and the holders. Thus, the body and the holders display the spectral variation of color and brightness based on the lighting change of the light emitting units, thereby illuminating the body for enjoying the view in the body, presenting the appearance of the body to attain different visual effects, enhancing the atmosphere of the space, and achieving the beautifying and decorating effects to further enhance the overall ornamental value and practicality.本發明懸空置式隧道型光譜魚缸，其主要在於透光缸體與支撐該透光缸體之透光支架係由透光材質所製成，以便設於該等透光支架底部之發光單元所散發之光線得以經由該等透光支架傳導至該透光缸體，並進一步透過該等透光支架及該透光缸體之周緣表面向外散射，以使該透光缸體及該等透光支架因該發光單元之變化呈現出顏色與亮度的光譜變化，不僅有利於觀賞該透光缸體內的水族景色，同時亦可完整呈現該透光缸體整體外型的美感，以利營造不同的視覺感官變化，提升整體空間氣氛，以及達到美化及裝飾環境等雙重效果，進而提升整體觀賞價值及實用性。
