A viral joke, "The first one goes to Blathers," from social media reveals a key sentiment of Animal Crossing: New Horizons players: every first catch belongs as a donation to the island's museum, curated by everyone's favorite owl. Whether or not a player is a completionist, having a full and complete museum can be a point of pride and show the effort the player has put into making their island home. The Museum collections are a great way for players to learn about nature and find purpose in the calming in-game acts of fishing, bug catching, and digging for treasures.

Many of the creatures that players donate to Blathers and the Museum are seasonal, making it a little more challenging for players to complete their exhibits. Moreover, developers are adding new content to Animal Crossing all the time, like the new sea creatures that came with the July update. As the game grows, the Museum tends to grow with it. At the time of writing, there are 80 fish and 40 sea creatures for players to find and donate, with more likely to arrive in future updates. Still, players can theoretically complete their Fish Gallery of the Museum right now with every available sea-dweller. Here are all 120 fish and sea creatures a player will need to catch right now to complete the Fish Gallery of the Museum.

What Happens When the Museum is Complete in Animal Crossing: New Horizons

Animal Crossing New Horizons Blathers

Right now, players may be disappointed to know there is no reward for completing the Museum. Blathers will express his gratitude for a player's generous donations, but not much else happens. Some players hope Animal Crossing: New Horizons will reintroduce the Museum gift shop, where players can sell duplicates of the creatures in the exhibits. Others hope a possible reward for collecting every possible item in the game arrives in future updates.
