I have a shelf with tempered glass (length 1.10m, width 40cm, thickness of tempered glass is around 1cm) and I want to put a fish tank on it; length of the fish tank is nearly 1m, width is about 30cm and height is about 50cm. If I fill water in the tank, it could be up to 100kg. Does anyone know whether the tempered glass can hold the fish tank ? Thanks heaps!!

Not sure but I'd also worry about the shelf mounting pulling out of the wall. That's why most tanks are sitting on a floor mounted base.
