The aquarium is a plastic bowl, whose plastic is very thin and will bend when you want, duly filled with Wassser, transport. Then there is the little Robo-fish. More is not included in this set. My recommendation: Dear high quality transparent glass or plastic bowl buy and get the fish individually to, then you can use the bowl to the end of the game still pass for salad, because that would not go with the delivered bowl. In addition, the bowl was scratched and stained. The fish swimming in the water at the funny bowl rim in a circle, but more it's just not. My children have every now and then placed the fish into the water and taken out again. They could but otherwise not much with it. My little (5J) carries the fish around with you. He activated by touching the tail, which he enjoys. But the fin is sensitive and falls off quickly. You will soon be gone. For the bath the fish is certainly very nice, but I can not recommend the Aquarium.
