Abstract
Abstract A device for separating newly born fish from other fish in a fish aquarium, the device consisting of a float supporting a generally opaque chamber-equipped frame on its underside and which carries a nesting tray spaced below the opaque frame. The frame is provided with small openings so that new-born fish may escape, from the adult fish and enter safely into the chamberequipped frame, the openings being designed so that the new-born fish may only pass upward therethrough and cannot return downward again.
