ARC Aquarium · published
Your aquarium just became four aquariums. This update adds multiple tanks, offline earnings, weekly goals, booster packs and 14 new backgrounds — plus a rebuilt progression curve so the full collection lasts.
Your decorations now keep earning while the game is closed. Come back to a "Welcome back" summary showing what you made. Previously, being away only meant hungry fish and a dirty tank — now there is something waiting for you.
Two packs — Freshwater and Reef — each give 3 random fish for less than buying them one by one. Species you have not discovered yet are more likely to appear, so packs help complete the collection instead of handing you duplicates.
Three small daily goals and one weekly goal, shown in the top-right corner. They reward EXP, and there is no streak to lose — miss a day and nothing breaks. The list hides itself once everything is done.
Every week one species is featured and sells for +75% once fully grown. The same fish is featured for everyone, so it is worth comparing notes.
The background collection grows from 9 to 23, and all of the existing artwork has been redrawn at full resolution.
Upload a screenshot of your aquarium to the Steam screenshots section. The nicest 5-10 aquariums, chosen by players and by us, will be added to a "Best Aquariums" gallery inside the game, credited to whoever built them.
We simulated thousands of playthroughs and found that the entire 125-species collection was being unlocked in around 7 hours — content meant to last for weeks. Levelling has been retuned so the full collection now takes roughly 150 hours to complete, with the early game left fast and rewarding.
Thank you for playing, and for every report and suggestion — several of the items above came directly from your messages.
