I used to have two 20-gallon long tank toppers. They were really handy to keep gerbils in because they would keep the burrowing material in the tank and I could put their wheel, sand bath, food, and water on the top. I cut a door in the front of it so I could reach in without having to lift the top. Quality Cages carriers 3 sizes 10-gallon, 20-gallon and 20-gallon long. They come in galvanized, powder coated white, powder coated black or, not pictured, powder coated silver-veined.
My boys 20 gallon bin cage with topper | The Gerbil Forum
Does anyone have any experience with the Martin's Two-Story 20-gallon long aquarium topper? The item number is RT-635. I plan on using this cage to house two female rats. Of course, I will cover the wire floors with something else to prevent foot damage.

My gerbils have sampled many a layout/aquarium. I had them originally in a tall 28 gallon. Then 20 long. Then a 110 qt Bin cage. And finally a 40 long. Then I DIY’d a topper to put on top. I change around their set up every time I clean out. I have large pieces of drift wood I trade out each time to keep it fresh. Various tunnels and bridges and such they bury down into the bedding. You can barely see the current drift wood I put in there. It was a smaller piece than usual. In the topper they have water bottles, a sand pot where they do all their business. A Gnawsome hut to chew on and they prefer to snack within with the treats I give them. The topper has 2 floors. Or two separate “lofts” where I put their food dish. Or just for a perch and look out. They are pretty spoiled methinks. They are worth it. My little daytime buddies!
It's a 20 gallon aquarium with a small animal high rise 'cage topper'
I've recently acquired a 20 gallon tank that would be a good option for my ratties... as long as I can find an aquarium topper! These are the cages that go on top of the aquarium so they get multiple levels and better air circulation. Does anyone, in Canada, know where I can find one? I called all the big and small pet stores around me and no one seems to carry them. One store did but only in the 10 gallon size.Made of 1/2" x 1" welded wire. The cages are made of 16 gauge welded wire and will last a very long time if not left outside to rust! This unit sets directly on top of a 20 gallon long aquarium . No assembly required. There is a long ramp going up to the first level. I use very strong door latches. There is no way your pet will escape this cage unless you leave the door open. Plus your critter will be safe from your cat or dog too!!
