With nearly half of galaxies in the local Universe residing in groups or clusters, understanding galaxy evolution in dense environments is key to understanding galaxy evolution as a whole. The environmental mechanisms that eventually lead to the quenching of star formation, which in turn causes an excess of passive galaxies in these environments, first and foremost affect the (cold) ISM. With the recent emergence of several world-class facilities in the Southern Hemisphere, we are now able to study this quenching process in unprecedented detail, even in the observationally more challenging low-mass galaxies, which make up the majority of the galaxy population in clusters. In this talk I will present results of my recent study of the resolved ISM (atomic, molecular, and ionised gas) of six dwarf galaxies in the nearby Fornax cluster, using MeerKAT, ALMA, and VLT/MUSE, revealing their surprising gas content.
