Aquariums are for fish, and that's the way it should be. I used aquariums for a while and had nothing but problems. My best enclosure at the moment is actually a rubbermaid stock tank (basically a large plastic cattle trough) with a wood top to hold in heat and some ambient humidity, and around 1' of dirt.
I think that where the reptile industry is right now, it's kind of like they are inventing products to try to solve problems that their other products cause.
I just think it's unsettling how, by following all the 'rules' for keepng russian torts, and using fancy lighting and things of that nature, my big gravid female would not lay. Within 24 hours of being put in an enclosure that breaks several well-known 'rules' for tortoise keeping (specifically temperature and ventilation), she laid her eggs, and both of the females have been thriving.
I DON'T yet suggest everyone do things the same way I did them, because I would rather not see it applied incorrectly (which could cause harm), but I think people need to experiment more with their husbandry. If we all just read what others write, we'll be at a stand still forever.
If anyone is interested in how I'm now keeping the females, I do have a post that I could link to on another forum, however, as I said, this is not recomended yet, as it's only been through just about 2 weeks of testing. I'm very proud of the results it is yielding thus far though.
