Anyone else use glass tanks for their rodents?

The biggest problem with the tabks is amonia is heavier than air.
I use to have a bunch of 20 longs way back when I started breeding rodents that I drilled 1/4 inch vent holes in the glass on the long ends.
I have since gone to racks because they are easier every way possible.

I like watching the rodents and making pets out of the breeders too!

So it's worth the extra maintenance time for me to have them in display type housing.
