I baked 3- 9×12 cakes and stacked them on a wrapped board with buttercream icing between each layer. The cake stand was a wine rack that I turned upside down.
I iced the Aquarium Birthday Cake in buttercream icing and cut out black fondant strips to make the frame for the aquarium. I air brushed the whole cake blue and I used candy melts to make the coral,fish and the no fishing sign. I made seaweed out of green buttercream and a leaf tip.
I found the big fish to go on top at a local thrift store and added some candy melt fish in his mouth. The starfish and #10 were also made from candy melts. I purchased fold out fish and hung them from the aquarium stand.
