i am thinking panda or pepper or the albino corys. i think steurbai are gorgeous but they get big, and i'd worry they'd get cramped up in my 18x12x30 tank
I'm not sure about storing toxins, but most sands, you'll want to rinse it first to get rid of the toxins. I have heard of someone (can't remember who) using sandbox sand and saying it didn't need rinsing? You probably won't want to stir sand as it will cloud up your water really badly. Most sands, you have to wait about 48hrs for it to settle.
As for the ammonia problem, I have not heard of that before. I would research that first.
