I have built up a small rockery into a bigger one using heavy river rocks. They are all stable and they are not high so even with digging i dont think there would be much falling far.
My question is, how much weight can a glass tank withstand?? is it 'anything goes'? i have postioned the rocks so they are not leaning on the back of the glass because i have used lightweight imitation rock as a buffer for this.
Tank is 4 foot, holds approx 55 gallons of water. Also, is there any best way to have the rocks ie. along the back, in the centre, in one corner???
