The Fish Emporium is a shop that sells various fish and equipment for the player's Virtual Tank. There are eight slots in total with two specially reserved for tank backdrops and the other for upgrades. Meryl the Mermaid restocks the emporium daily at midnight based on time set on the player's computer; once an item is purchased, the stock for it will be empty until the next day. jgMq58w2Rzc.
