Die Idee eine fette schwarze Pyramide (evtl als Höhle aus geklebten Schieferplatten? ) aufzustellen, brachte die Frage auf, welchen Stein ich nutzen kann, hier eine gefundene Liste von caudata.org:

Below is a list of rocks that are safe for aquarium use.
Safe Rocks:

Granite (care must be taken with granite, some forms contain high concentrations of pyrite)
Jade
Microcrystalline Quartz, also known as Quartzite and its metamorphic forms: Jasper, Agate, Chalcedony, Sard, Carnelian; Green coloration should be avoided due to presence of copper)
Onyx
Petrified Wood
Slate
Basalt
Porphyry
Schist
Commercially available “River Rocks”
Mica
Tapecrete or similar acrylic based concrete products, properly treated and sealed
Obsidian

Unsafe Rocks:

Lava Rock, not recommended due to a multitude of sharp edges and the possibility of high sulfur and hydrocarbon concentrations
Coral, causes alkalinity issues
Dolomite, the metamorphic form of limestone
Fools Gold also known as pyrite (or any other rock with metallic veins - Acid Producing and even more so, often a lead hazard)
