This lid is CNC-cut from 3/8″ clear polycarbonate to the outside size of the JBJ Nano RL 20 (20 Gallon AIO)'s glass, with a lip that sits inside the glass so it cannot slide and a mesh window in the middle for optimal gas exchange and light penetration. It works as a screen top and jump guard: fish and invertebrates stay in the tank while light and air pass through. The Nano RL 20 (20 Gallon AIO) is an all-in-one tank, so the lid covers the display area and stops at the filter chamber wall.
Add a feeding hole with a black or white cap, cutouts for hoses, wires and light mounts, a feeding cup or a removable evaporation cover in the configurator above. You approve a digital proof before anything is cut, and the lid ships free to the contiguous US, usually within a week. If it doesn't fit because of our error, we remake it at no charge.
The Nano RL 20 is the largest of the Nano RL line, and the lid is cut to its display opening, ending at the rear chamber wall so JBJ's chamber covers, pump and media stay as they are. The lip sits inside the glass; the mesh window passes the light from an LED mounted on the back.
At twenty gallons people add wrasses and firefish, the two most reliable jumpers in the hobby. Put the feeding hole where you feed and add a cutout for an auto-feeder or a cord if needed.

JBJ Nano RL 20 (20 Gallon AIO) Lid Questions
- Is the Nano RL 20 lid the same as the JBJ RF-45?
- No. The RF-45 is a different footprint with its own template. Order the model printed on your tank.
- Is the JBJ Nano RL 20 (20 Gallon AIO) lid one piece?
- Yes. The Nano RL 20 (20 Gallon AIO) lid is a single panel of 3/8-inch clear polycarbonate with a mesh window, so it lifts off in one piece.
- Does the lid come with a feeding hole?
- A capped feeding hole is an option in the configurator: choose a black or white cap and drag the hole to the corner you feed from. A feeding cup that holds food at the surface and a removable evaporation cover over the mesh are optional too.
- Will the lid work with my light?
- In most setups, yes. The lid sits inside the glass below the rim, where arm mounts and clip-on lights attach, and the mesh window passes the light. If a bracket, a hang-on filter or a cord crosses the glass, add a cutout for it in the configurator and it shows on your proof before we cut.
- How long does a JBJ Nano RL 20 (20 Gallon AIO) lid take?
- You approve a digital proof first; the lid is then cut and ships free to the contiguous US, usually within a week of approval.
- What if the JBJ Nano RL 20 (20 Gallon AIO) lid does not fit?
- Every catalog lid is guaranteed to fit the model it is listed for. If it does not fit because of our error, we remake it at no charge.
