Go easy on feeding too, even missing alternate days. Higher temps mean the fishes' metabolism is higher, requiring more oxygen. Digesting food takes effort, so the less the better. Feed sparingly and less often.
Increased aeration and surface disturbance is also helpful on the oxygen issue, and the fan across the surface helps there too--provided you don't have fish likely to jump, though you can lower the water level some.
