The lid is designed to create a mechanical enclosure to the tank and at the same time maintain an optimal visibility of the fish. It is made of transparent polycarbonate plastics, in the same color of the tank (there is no alteration of the light in the tank).
The design features a hole for the inlet of the water (not flexible tube is required) and a cone-shaped hole for the introduction of food. The lid can be easily lifted (with water supply tap shut off) to gain accessibility to animals keeping the tank on the rack.
The dome-shape allows keeping all the water evaporation inside the tank and moving all the relevant drops on the side, guaranteeing a perfect visibility at all time.
The lid can sustain autoclave cycles up to 250 F.
