Crystal clear TerraTopper acrylic lid is the perfect way to turn a fish bowl, vase or any piece of glassware into a sealed vivarium, mossarium, or terrarium. We can cut a custom lid - either solid or with ventilation holes - to perfectly fit any diameter under 11.75” so you can control humidity and condensation while letting in light from above and controlling air flow.

**FREE SHIPPING**

Perfect for topping your favorite piece of yard sale glassware! Turn almost anything into a DIY mossarium or terrarium. Missing or broken lid? No problem! Just get an accurate measurement of the outside diameter, and top it with a crystal clear clear, 1/8” acrylic round with smooth edges. Any jar can be repurposed into a terrarium with the ability to control moisture and airflow, and with the option of micro holes, you can even keep insects as small as fruit flies in our out while still allowing air flow. Easy to remove for cleaning and maintenance. Lid with micro holes is a great alternative to cork for covering Marimo moss ball micro aquariums.

Diameter 1” to 11.5" or custom order any size in between. Don’t see what you need? Want a custom shape or hole size or pattern? Just ask! Please just be absolutely certain of your measurement as that will be the exact size of the lid (You don’t want it extending too far over the lip of the container, and if you give the measurement of the inner opening, your lid will fall into the container!)

Perfect for:

Beta tanks
African violets
Carnivorous plants
Isopod terrariums
Fruit fly cultures
Mossariums
Micro vivariums
Moss ball aquariums

. . .and more!

Free clear silicone stops included to help secure the lid, if desired.

Chose from:

Solid lid (no holes - for high humidity or completely arid/artificial terrariums only).
Vented lid (1/8” holes for maximum air flow)
Micro holes (small enough to keep insects as small as fruit flies in or out while allowing adequate airflow)
