  2. Build a layered habitat with gravel, plants, and hiding spots, then add the toy fish and water.
  3. Observe the habitat and discover it's too crowded or missing hiding spots, then rearrange the decorations.
  4. Present the finished aquarium to visitors, explaining how each part helps the fish survive.
