Flower pots in tank

[eng55]

I was going to break a couple of flower pots in half and use them for caves in my aquarium. Do I need to treat them with anything besides cleaning them off before I put them in my tank? Also another thing is that I want to glue some of my gravel in tank on them and was wondering what type of glue is ok for the fish? Any info would be appreciated
Thanks

Yes, flower pots are fish safe. Silicon will be the best thing for adding bits to the outside of them.

Just have to make sure that the silicon you use is aquarium safe.

i did the same thing a couple of months ago i just used reg aquarium silicon on it and it looks great. i sugest taking your time when putting on the gravel so you completly cover it.
