If you don’t like the way and the area in which a decoration or plant you bought was placed in your aquarium, you're more than welcome to change things up. To relocate, resize, or rotate an item, do this:

  1. Tap the item to open the menu below it 📑
  2. Enlarge, shrink, or rotate the item by tapping the plus, minus, and arrow icons, respectively ➡️
  3. Tap the item and drag it around without releasing your finger to relocate it.
