is waterproof silicon good as aquarium silicon to put rocks together to make caves 4 my cichlids?

Question

what about even normal silicon ????

Answer 1

Not just any silicone will do. It doesn't need to be specifically for aquariums, but it must at least be labelled 'food safe'.

I keep about 200 lbs of rocks in my tank for my cichlids and would never silicone them together - that way I can easily redecorate at whim and remove much more easily.

Answer 2

I would stick to aquarium silicon, as some silicon have chemical additives that are toxic to fish.

Answer 3

Sorry i thought they were the same thing, silicon sealant works well at sticking rocks together for cave structures.
