Securing Rocks?

[stucolls]

Hi guys

I grabbed some nice rocks from the garden and cleaned them all up, sterilised etc

What can I use to stick them together to form a scape?

You could use aquarium silicone sealant
Like this (http/www.seapets.co.uk/products/aquarium-supplies/fish-tank-equipment/aquarium-sealers/silver-label-clear-aquarium-silicone-sealer-310ml.html)

Or aquarium putty.
