Aerator

[direfishking27]

should I have an aerator in my tank or is it not necessary?

Are you running a skimmer? If so, then no, its not needed.

 

[direfishking27]

No I am not would I need one on a 25 gallon tank

No, you don't need a skimmer on a 25g tank. You really don't need to aerate either, 10% water changes a week, and running powerheads breaking the water surface will suffice.
