Since a 12 gallon tank will actually hold considerable less when in use (Tanks are never filled to the brim and usually have some water displaced by gravel etc) The maximum amount of fish would be less than 12 inches. (around 10 inches) The basic rules of sucessfull fishkeeping are. :- 1 inch of fish needs at least 1 gallon of water. :- Every tank must have a permanently running 'cycled' filter. :- Every tank needs at least 50% of its water replaced every week. Folloe the above and your fish will stand a chance of survival. Fail to follow them and I can guarantee that your fish will be constantly getting sick and will live a shortened lifespan.
Depends of the size air raider you have, & how fast it pumps more oxygen into the water.

The only fish you can keep in a 5 gallon tank is one betta (Siamese fighting fish) on it's own as that is a very small tank.
The rule of thumb is usually a gallon per fish, so six gallons would be good. If the fish are on the large side (like a goldfish), then a seven gallon tank would be ideal.
