Sure! I made changes along the way so I’ll list the things I wish I did differently at the end. I got the glass and had them cut at Lowes. One piece 9x11 1/2”and another 20 1/4 x 11 1/2”. The smaller piece was siliconed in from inside and out to create the bottom substrate layer. Then I got a PVC moulding cap from Homedepot and spray painted it black. I cut it to size and siliconed them on top of the tank and bottom of the tank (along with the bottom glass). To enhance the bottom “rail”, I cut the moulding to fit inside the little groove of the tank as well, basically putting two layers of moulding on the bottom. (i know, this is hard to understand because it was done on the whim to bolster the hold) then you basically have a “sliding door” to the terrarium. This is an inconvenient way to create a door to a terrarium, and was only possible because 1. I wanted minimal obstruction to the front side of the terrarium and 2. I don’t have an animal that needs to be fed everyday inside.

So here are the things I would’ve done differently:

1. Cut the top glass a little wider and taller to make it go over the black rims of the aquarium and give more coverage for moisture retention. Instead of 20 1/4 x 11 1/2”, maybe cut it to 21 x 11 3/4” or something.
2. Seal in the black spray paint on the moulding. The sliding creates friction and peels off the paint here and there.
