You could house your animals in clear, polycarbonate boxes. These will be about the same weight as aquaria but much easier to clean due to the rounded bottoms.
The only downfall to these vs. aquaria is that you need to be a bit more careful not to scratch the material.
In the future you could incorporate them into a rack system which would save a lot of husbandry time.
I found a picture recently of a rack built around these boxes. It looked fantastic. Wish I could find it.
