This would not be good to do mainly for 2 reasons. First, fish need oxygen in the water to live and oxygen gets in the water (and CO2 gets out) at the surface. It's a false myth that an air pump will add much oxygen to a tank. Studies have shown that very little gas exchange occurs on the surface of bubbles as they rise through the tank. It does help in that it brings water from the bottom of the tank to the top and constantly moves the refreshed water into the tank.
Secondly, with a small mouthed bottle it would be very difficult to feed and otherwise care for the fish.
Use a container with a large, open top for plenty of exposure to fresh air and you will have far better success with keeping fish. What you are suggesting would also certainly lead to killing fish needlessly.
The simple answer is yes.

If you have a heater, turn it off.
yes, it is actually better, as some fish can be frightened. Never turn on the light after newly buying and releasing fish into your tank.

The tip of his little nose. Press the right side to make your fish turn left, and the left side of his nose to make him turn right.
No, It will react with the acrylic and turn it cloudy!
Yes but i would make sure it has a lid with ventalation screen mesh is a good option. if a tropical gecko you could turn the fish tank up so its higher than it is wider ( arboreal ). usage of a heat Matt on a fish tank unless the fish tank is raised ( feet on bottom) you would have to put it one the side or back to stop the glass from cracking. basicly fish tank is the same as a terrium you will just have to adjust tiny little things :]
