We present extended Lyman-{\alpha} (Ly{\alpha}) emission out to 800 kpc of1034 [O III]-selected galaxies at redshifts 1.9<z<2.35 using the Hobby-EberlyTelescope Dark Energy Experiment (HETDEX). The locations and redshifts of thegalaxies are taken from the 3D-HST survey. The median-stacked surfacebrightness profile of Ly{\alpha} emission of the [O III]-selected galaxiesagrees well with that of 968 bright Ly{\alpha}-emitting galaxies (LAEs) at r>40kpc from the galaxy centers. The surface brightness in the inner parts (r<10kpc) around the [O III]-selected galaxies, however, is ten times fainter thanthat of the LAEs. Our results are consistent with the notion that photonsdominating the outer regions of the Ly{\alpha} halos are not produced in thecentral galaxies but originate outside of them.
