This is the Add A Sphere.  I have wanted one for years.  My wonderful children bought me this one for my birthday.

The fish will swim up into it to get the food I put into the sphere.  Right now my sphere is green with algae.  I want to wait to clean it until the fish are more comfortable swimming into it.  When it is clean the show will really begin!

If you watch closely you’ll see the baby fish swimming around at the base of the sphere with the big fish.  The babies have been enjoying the sphere since it was first installed.
