On the corys, some species do like a bit of water movement, some don't care. I see Corydoras agasizzii isn't in the profiles yet. BTW, the correct spelling of the species epithet is with two "i". It occurs in the Amazon basin along the Peru/Brazil border in streams and flooded forest. It should do fine with neons, which actually occur in the same region, though perhaps not in the same streams as the cory, not sure on that.
Most fish will swim against a current because they naturally expect food particles to be carried downstream in the current. As long as fish which do not permanently live in currents have a place in the aquarium where they get get out of the current, they'll be fine.
Should I also boil it along with the bleach soak?
The cories I have are going to stay in the 46. They love the stream so much I would hate to get some of the same to put in the 12 with no current. That's why I was asking for a suggestion on what type are more laid back and chill along the bottom. These cories are very, very active. The bottom left half of the tank is where the current dies out and is fairly still. That's where they rest.
