Rocks against tank walls???

[AngryTom4]

So is it a good idea to lean some of the rocks in the tank up against the walls? It seems like it would be too much weight for the glass but i have seen pictures of ppl doing it. If i cant then how would i get the round rocks to stack good without having the chance of them falling?

Mine are against the glass in some spots but I try to avoid this whenever possible. One thing to do is to silicone your rocks toghether or posssibly to the glass but I would avoid this if you can because it certainly comes anoying when trying to catch fish or adjusting territories because you become so limited in later movements of the rocks. Stacking rocks take patience but it's worth the time and effort to get them done right. Avoid silicone and leaning against the glass whenever you can it's just an option. Good luck
