I have a new thirty gallon tank, with a canister filter, I plan on adding fish later this week, and didn't want to incur any problems.

if your fish dont look like they are struggling to breathe then u have enough oxygen

Just depending on the size of your tank, and the type of filtration you are using (Biowheel/HOB or Canister) you should not have any worries.
Which do you have?

You can actually see their gills moving if they are having problems breathing.
They move a lot more when they have air...wouldn't you?

I think they sell oxygen meters.

if they are moving very slowly, the O2 level is low.
