Angel fish are light sensitive. They figure that light is always coming from the sky, so, if the room light is brighter than the tank light and the tank has a dark top, then the angel fish will look straight up thinking that it is correct and wonder why you are lying down and floating.
On it's side-on it's back, or on it's literal dorsal fin-on it's back
Probably a large Cory catfish (they only get to 3-4 inches) so that it doesn't get eaten or attacked by the Angelfish. P.S. the Angelfish needs a tank of at least 30 gallons to be happy.
Angelfish have gills that extract oxygen from water. Without water, they would suffocate and die.
Yes
Yes, because you would be looking straight at the Sun.
If you are looking straight at the front of your car, camber is the adjustment that swings the bottom of your tire either out, (away) from your car, or in (under your car). hopefully you can see how this would change the feel of turning.
The betta.
Yes they would. In a compatibility chart on PetCo.com, it was seen that angelfish will work well with barbs. Your welcome

Well, the guppies might nip the angelfish's fins, which, in return, would cause the angelfish to chase and possibly eat them. The angelfish would terrorize the danios and tetras by chasing them. Quick side note: if you are planning on keeping a platy, I really wouldn't keep one! They're quite social fish, and they like to be in small groups. Basically, the angelfish will chase any small fish. The biggest problem you will encounter with this aquarium setup is the fight between the angelfish and the betta. I know from experience-I kept an angelfish and a betta together in a tank myself, and the betta ended up dying. The angelfish will nip the betta's fins, and the betta will nip the angelfish's. They will chase each other and bite a lot. My betta had fin rot and died because the angelfish had caused the fin rot to grow due to the fact that she had torn off all of his fins. I would definitely rethink this aquarium setup.
If you are looking at the A4 paper portrait on the sides it would be 29.7cm and the top and bottom are 21.0cm.
There is nothing poisonous in or on an Angelfish so they are edible (as are most fish) but I would have thought they were expensive to eat and not a really large enough to satisfy a large hunger.
