HII galaxies are dwarf galaxies which are currently actively forming stars. We speculated that an interaction with an optically faint, but gas-rich object might be responsible for their enhanced star formation. This prompted us to search for companions with the VLA in the 21–cm line of HI. This has several advantages over optical searches (Campos–Aguilar et al. 1991, AJ, 106, 1784; Telles & Terlevich 1995, MNRAS, 275, 1), e.g., the direct availability of redshifts.
