All newsPlayers around this dateRead on Steam

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 nothing you need to do.

Every fish redrawn

  • All 125 fish have new art: rounder bodies, big friendly eyes, visible scales, bolder outlines and much brighter colors.
  • Every species keeps its real shape and markings. Long, slender fish like the kuhli loach stay long and straight, so they still swim smoothly.
  • Your cards in the collection book, in My Cards and in pack openings show the new drawings.

Plants and corals redrawn

  • Plants have deep, rich leaves with bright highlights and lighter patterns, just like the original ARC art.
  • Every plant is now a full bouquet: leaves open forward, backward and to the sides, with short leaves at the base for a thick, natural look.
  • No more soil or roots under the plants: they grow straight out of your sand.
  • Corals have real depth now, with shading, hollows and thickness.
  • Plants of the same family, such as the three anubias, now look clearly different from each other.

Bigger tanks

  • A fully upgraded tank now holds up to 100 fish and 100 decorations (it was 50 and 50).
  • Every upgrade gives more room: fish 10, 25, 45, 70 and 100; decorations 20, 40, 60, 80 and 100. Tanks you already upgraded get the new room right away.

Card packs

  • Card packs no longer have a daily limit: open as many as your gold allows.
  • The free Gift Pack still refills on its own timer.

Fixes

  • Settings > Reset Game works again after you confirm.
  • Clicking an empty spot in My Cards no longer closes the window.

🐞 Found a bug? Please tell us in the Steam Discussions. We read every report, and most issues can be fixed right away.
