Use a new or well-cleaned goldfish bowl. Mix gelatin according to package directions, substituting curacao for water in whatever ratio you prefer. Place the hard candies in the bowl. When gelatin is cool but not yet setting up, pour it slowly into the bowl and be careful not to disturb the candies or the color will run. Cool until half-set then add foliage and fish, placing them with strands of spaghetti. Refrigerate until serving-time. The best Aquarium Jello drink you've ever drank!
