ARC Aquarium

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 full catalogue of 250 species. Nothing else changed — no balance, no prices, no save data. If you play in anything other than English, open any collection fish and you will see its description in your own language.

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 before it does anything. Locked fish are never touched. Name your fish Click any fish and you can give it a name. Naming a fish locks it automatically, so your favourites can't be swept up by Sell All or a stray Shift-click. Unlock it whenever you like and it becomes sellable again — the name stays. The game now follows your Steam language On first launch the game uses the language you picked for it in Steam, then falls back to your system language. If you already chose a language in-game, nothing changes — your choice is never overwritten. Spanish (Spain) and Brazilian Portuguese are now listed as supported languages too. A tidier interface The bottom bar went from twelve buttons down to five. Collection, Achievements, How to Play, Settings, Touch, Light, Share and Community now live under a single Menu button. Settings and the fish detail panel scroll now, with a visible scrollbar. Nothing gets clipped on ultrawide monit

Fixed cures not working: a cured fish now stays healthy instead of falling sick again seconds later. Fish now need 7 days without food to get sick, up from 24 hours, and time spent in a background tank no longer counts against them. Fish that are currently sick under the new limit heal themselves automatically.

125 new decorations The decoration catalogue has been rebuilt from the ground up. The old 86 decorations are gone, replaced by 125 hand-drawn aquatic species — freshwater plants, seagrasses, macroalgae, hard corals, LPS and soft corals, each with its real name in the shop. Your existing decorations will look different. They keep their spot, their size and their earnings, but the artwork underneath them is new. Nothing was removed from your tank. One new decoration unlocks at every level, all the way to 120 Prices now run from 10 gold to 1,500,000 gold, so there is finally something worth saving for late game Every decoration you already own earns at least as much gold as it did before — no income was reduced The most expensive decorations pay back slowly on purpose. They are a way to spend gold, not a money printer 26 Steam Achievements Achievements are now real Steam achievements with their own icons. If you have already met the requirements, they unlock the moment you launch this update — collection milestones, gold, levels, breeding, cleaning and feeding are all counted from your existing save. Expect a burst of notifications on your first launch. Achievement icons now also appe
