In this work, a kind of aquarium lamp is proposed, which is set in a aquarium.The aquarium lamp has at least one first ferromagnetic element and a lamp.The first ferromagnetic element is arranged on the outer wall of the aquarium.The lamp is arranged on the inner wall surface of the aquarium, and has at least one second ferromagnetic element, the second ferromagnetic element and the first ferromagnetic element are separated and attracted by the aquarium.Therefore, as long as the position of the first ferromagnetic element is changed, the aquarium lamp can be adsorbed on the top cover, side surface or suspended internal space of the aquarium.Therefore, in addition to providing direct illumination for the fish in the aquarium, it can also irradiate the fish from different directions, so it can make the color of the fish more distinct and have a more specific visual effect.本創作提出一種水族箱燈，其設置於一水族箱內。水族箱燈具有至少一第一鐵磁性元件及一燈具。第一鐵磁性元件設置於水族箱的外壁面。燈具設置於水族箱的內壁面，並具有至少一第二鐵磁性元件，第二鐵磁性元件與第一鐵磁性元件以水族箱相間隔且相吸。因此，只要改變第一鐵磁性元件的位置，本創作的水族箱燈可吸附於水族箱的頂蓋、旁側面或或懸吊內部空間內。因此除了能直接對水族箱內的魚類提供照明外，還能由不同方向照射魚類，因此能使魚類的色彩更鮮明且更具特異之視覺效果。
