We now have mesh and solid vent inserts for the Thrive 18x18 tank. The tank has a built in vent section at the top above the door which has some fairly large holes. The holes are so large fruit flies just walk on through. Our mesh will keep the flies contained within your tank, especially if you are pairing it with our TV18 lid!

These 3D printed tank vent inserts are designed specifically for the Thrive Tropical Reptile Terrarium Essentials Kit – 30 Gallon (18" × 18" × 24"). These are accessories for the original tank vents and are not replacement lids . They are designed t

We are moving our website over to a new host so it may be wonky for a day or so while all the things get settled. If it seems like it isn't right just check back in a day or two and it should be all good.

Here is a great video on making a dart frog terrarium using one of our lids! Shows the assembly of the lid as well around 8:45 if you're interested in seeing one put together. Personally I'm terrible at cutting glass so just get Lowes to do it, but it's obviously possible to do it yourself as he demonstrates beautifully.

We now have a lid for the 10 gallon front opening Zoo Med tank! Weirdly while it is not listed on the Zoo Med website, this is a tank that is indeed available at Petsmart. Because the lid is quite long, you'll need to get your own glass or acrylic on this one as shipping 18" long acrylic would be too likely to break.
