When can you play a Red God to score a fish tile?
The Red God entry limits it to expansion and to one Red God per region per player.

Only when you expand, as you place your hut on a new region's building space. Playing it is optional and costs an offering, so you may hold it back to score a bigger fish when you expand later. Each player can play at most one Red God per region.
