Silicon safe for fishes

[Saint888]

Hi may I know what silicon to use if I want to glue rocks to the bottom of the tank? I wish to form a wall of rocks as I do not want the rocks to collapse after planting. What silicon will be sufficient to do the job yet later part if I were to remove the rocks, I can remove it without living much residue?

Some people have tried to stick rocks with silicone, but some are successful with it while some others are not.

If silicone is used, it is important to ensure that the stuff is fully dried first before submerging it with water. Leaving it for 24 hours should be enough, but 48 hours is better, especially on humid days. If it is submerged before it is completely dry, then it will not last long and thus give headaches after some time.

Removing silicone cleanly from rocks is not so straighforward, as it sticks well to the rough surfaces.
