I don't keep rats, I don't know what is good substrate, I am however aware of how people warn against aquariums for them and have myself read up about why rats owners tend to recommend people into looking into rats away from tanks. Its not that they cannot be kept in glass aquariums just that they require you to be much more aware of urine and ventilation of the ammonia from said urine. Because of that rats owners tend to try and sway people to rabbit or ferret type cages, those that have solid bottoms but are wired for the rest because they have much better ventilation and there is less risk to the rats respiratory system.

They do have sensitive systems, I would look into proper rat care and substrate, always look and spot clean.
