These are my first frogs. I have a 24 year old ball python I moved into a 75 gall aquarium. So I used his old terrarium from 1992 made by oceanic. This has 4 vents close to the bottom and a vented lid. When I was moving it into the house my son broke the lid. I ended up cauking it back togther after going on oceanic's web site and saw they don't even do viv's anymore. And there's nothing like it in the stores. Is it beacause they are simply out of style, or beacause they weren't practicle somehow? I think the ventalation is adequite. We'll see how gross it is after my fist 3 week cleaning.
