A liquid injector for a closed aquarium, comprising: a piston having the piston, and ejecting the liquid filled in the cylinder portion from the ejection port by pushing the piston toward the closed end side of the cylinder portion; It is characterized by comprising: an air passage passing through from a position further from the tip to the tail end than the seal part, and an opening/closing plug provided at the opening on the tail end side of the air passage and opening and closing the opening arbitrarily. A liquid injector for closed aquariums. (2) In the liquid injector for a closed water tank according to claim (1), a shielding plate having a length smaller than the inner diameter of the cylinder portion is provided on the insertion side end surface of the piston so as to be substantially orthogonal to the axial direction of the piston. A liquid injector for a closed aquarium, which is characterized by being attached.
