I had the volcano back post because he is an extreme smell of paint ran out - which is then passed into the water. While it is on the packaging that only non-toxic materials were used, but I can not quite believe in this extremely chemical smell. The volcano was no longer attached to the packaging but "was" the wrong way round it. (Probably otherwise glued with silicone on the surface of cardboard, remains of which were still at the volcano base). But he does, in fact, in conjunction with a "Farbausströmer" a "good figure" in the aquarium.
