Review on Underwater Adventure with Uncle Milton Undersea Encounter Aquarium and Viewing Scope by Christina Jones

Very, very easy-care toy. Gravel is extremely difficult to remove and clean without wetting the cardboard backing. After a cleaning, the cardboard background will get wet and that's it. Plastic scratches very easily, parts of the periscope break off easily. Goldfish need a lot of water and that is not suitable for many species of fish. I've never struggled so hard to keep a toy intact, the fish alive, and the tank clean. NOT recommended at all. Save money on a "real" tank.
