SCG0018-4854 is a remarkably high galaxy density and low velocity dispersion group with evidence of a recent interaction. We obtained VLT FORS2 optical observations and we present spectroscopic and photometric evidence of how dramatically galaxy interactions have affected each of the four member galaxies. We found peculiar kinematics for each galaxy and evidence of recent star formation.
