Galaxies in groups and clusters are subject to a variety of environmental influences that can affect their evolution, such as ram pressure stripping, encounters with other galaxies, and tidal mass loss. The Hydrangea simulations are a spin-off from the EAGLE project designed to study these processes and their expected imprints on the cluster galaxy population. I will introduce these simulations and highlight some successes – and failures – that have emerged from comparison to observations. To illustrate the insight that can be gained from them, I will then discuss what they predict about the fate of satellite galaxies in clusters (and groups): are they disrupted rapidly after accretion, or can they survive in the harsh cluster environment?
