Thank you to the player who told us "有的地方没有ä¸æ–‡" (some places have no Chinese). You were right, and it was worse than it looked. Chinese, Japanese and Korean A single blank line in the Simplified Chinese, Japanese and Korean language files made the game stop rea…
Thank you for diving into the Card Update! This small patch fixes the issues found in the first hours after release. Your saves are safe and there is nothing you need to do. Rewards and selling Collection milestone rewards (Rare Deck and Legend Deck) are now g…
ARC Aquarium has been rebuilt around one idea: every fish, shrimp, seahorse, jellyfish, plant and coral is now a collectible card. This is the biggest update the game has ever had, with new gameplay, newly drawn creatures, a new tank and a brand-new collection…
Localization update The 125 collection fish added in the last update had their descriptions written only in English. Now every one of them is described in all 23 supported languages, the same as the original 125 species. 2,875 fish descriptions, covering the f…
125 New Collection Fish The store now has a separate Collection tab with 125 showcase species, bringing the catalogue to 250 fish in total. They exist for one reason: to give your late-game gold somewhere to go. A collection fish arrives fully grown — no egg, …
This update is about cutting down the busywork and tidying up the interface. Sell All A new Sell All button appears in the bottom bar whenever you have grown fish ready to go. One click sells every grown, unlocked fish, and it tells you how many and how much b…
Hi everyone, and thank you for playing ARC Aquarium! Our small studio just released a brand new game on Steam, and we wanted you to be among the first to know. Prismhold is out now Prismhold is a card-driven tower defense: every tower is a card. Build a deck f…
Thank you for the great ideas! This update comes straight from a player's suggestion: checking every fish for a merge meant clicking them one by one in the water, plants kept getting in the way of those clicks, and taking a tank apart for a new layout meant re…
Thank you for playing ARC Aquarium! Version 2.6 is all about the first hours. We watched how new aquariums start and found long quiet stretches where there was nothing to do. This update fills them, removes sickness for good and makes opening packs feel quicke…
Thank you for the reports! Version 2.5.1 fixes the two problems you told us about. Your fish, cards and gold are all safe, and there is nothing you need to do. "My merged fish disappeared" No fish were deleted. Every merged copy was added to another fish of th…
Happy Halloween! Version 2.5 brings a limited-time Halloween Festival and a big round of changes you asked for. Your gold, cards and tanks are all kept, and there is nothing you need to do. Halloween Festival (until January 7) Open the festival with the new pu…
Thank you for playing ARC Aquarium! Version 2.4 adds Steam leaderboards, so you can finally see how your aquarium compares with other players. Your gold, cards and tanks are all kept, and there is nothing you need to do. Example leaderboard with sample players…
Thank you for playing ARC Aquarium! Many of you told us you loved the bright, colorful look of the original art. Version 2.3 brings that look back to every fish, plant and coral in the game. Your gold, cards, tanks and decorations are all kept, and there is no…
Thank you for playing ARC Aquarium! Version 2.1 changes where gold comes from: your aquarium itself is now your income, so keeping and merging your cards always pays off. Your gold, cards, tanks and decorations are all kept, and there is nothing you need to do…
This update is all about how the fish move. Schooling Fish of the same species now swim together. Each school follows a leader and holds its formation instead of drifting apart, so a tank full of neons reads as one shoal rather than twenty separate fish. Forma…
Fixed Gold no longer breaks past 2.1 billion. Any balance above 2,147,483,647 wrapped around into a negative number, and restarting the game reset it to zero. Gold is now stored as a 64-bit value, so that ceiling is gone. If your save already went negative, it…
