Should I use an air pump?

I recently stocked my 75 gal fw tank. I'm using an air pump with two air stones for medium size bubbles. I wanted to be sure there is enough oxygen in there. Should I use an air pump with cichlids? I faithfully do a water change every week and the tank is not over stocked. The fish are doing great except for one that is always hiding even at feeding time. I thought the bubbles might be scaring that fish.

What kind of filter are you using? Usually the surface agitation from a HOB or Canister filter creates enough gas exchange for proper oxygenation.

I'm using a Fluval 406 cannister filter.

You should be fine. The fish will gasp at the surface and seem distressed if there isn't enough oxygen, just watch them.
