Make every angle of your Neptunian Cube M-Pro 120 feel considered. Meet the PolypTop for Neptunian Cube M-Pro 120, a made-to-order mesh-style lid created by The Polyp Pros. Your Neptunian Cube deserves a lid that follows the same crisp, contemporary look as the aquarium itself, with practical space for your equipment. Its open-mesh centre helps discourage jumping fish without hiding the colours and movement of your reef.

The M-Pro 120 is the starting point for the design; send the specific generation and equipment layout so we can plan your lid properly. Our goal is a smart, restrained look that complements the aquarium rather than competing with it.

Your lid, your layout. Tailor the top to your setup before we manufacture: light mount cutouts for brackets, cable/wire cutouts for equipment leads, and an optional frozen-food feeder hole for convenient feeding. Choose Yes or No for each option. If you need cutouts, use the Additional Cutout Instructions comments box to describe the type of cutout, quantity, approximate dimensions and exact positions (for example, a rear-left light bracket cutout, two rear cable openings or a front feeding hole). Leave the comments box blank if no cutouts are required. A feeder or feeding cup is not included.

Fit check before manufacture: Please provide the exact Neptunian Cube model and generation, measurements of the tank rim and a photograph taken from above. We will confirm your layout and cutout positions before production. This listing is for the PolypTop lid only; aquarium, lighting, mounts and other equipment are not included. Tank brand and model names identify compatibility only; this is an independent The Polyp Pros accessory, not an original Neptunian Cube product.
