What's New in Sim Aquarium

3.7.3

September 2, 2026

Switch between aquariums and fine-tune your decorations with greater confidence. We fixed a crash that could occur after moving to another aquarium and then resizing or flipping a decoration. This update also improves how the decoration toolbar handles aquarium changes, helping your fish tank stay responsive while you decorate, relax, and care for your fish. Additional stability refinements reduce unexpected interruptions during everyday aquarium play. Thank you for caring for your underwater world. We’ll keep improving the experience with every update.
