Gasping at the surface indicates poor water quality or low oxygenation. Check the chemistry, especially ammonia and nitrite levels. Ideally, you want them to be 0 ppm. Use only aged or conditioned water that is temperature matched for water changes. This will prevent stress or shock. If the chemistry is fine, check the temperature and consider adding in an air stone or bubble wand to increase oxygenation.
