Show objects in regular tanks

Build a small show exhibit. Make sure the animal you are going to put in your exhibit can use the show toy. Then, build a regular tank around it, but leave one piece of wall out so that it does not fill. Then, delete the show tank but not the show toys. The show toys will now be on the ground inside of the almost completed tank. Fill in the rest of the tank so that the toys are in the water. The toys will float up. Your aquatic show-performing animals can always play with show objects as though they were performing a show. Note: You will not get any money as you would with a regular show, but it makes your animals happier.

No rubble or trampled terrain

Block off part of the exhibit then put terrain that can be trampled there. In their part of the exhibit, put Dirt, Sand, Brown or Gray Stone, or Snow. You can also use water as a fence if the animal cannot swim.
