The Aquarium is a location in Harvest Moon GBC 3. It can be found on the mainland. Here, the player will find that the aquarium is empty and there are no fish in the tanks. Upon talking to Cozy, you will be tasked with stocking said tanks. By gifting Cozy fish you will be able to help grow and fill the aquarium - and, at the end, in return for a completed aquarium Cozy will gift you with a Power Berry.
The player may also view their hard work by walking up to any of the tanks and selecting them. It'll tell you how many and what kind of fish is in the tank before pulling up a screen that shows what's going on inside the tank.
