Aquarium safe adhesive?

A good safe adhesive that can attach rocks to plastic? I have a couple of corner caves I bought off of Etsy. I thought they were the legit kind but they’re more of a knock off (3D printed and float horribly). I plan on trying to make them work in my 40g but I’m going to attach slate rocks and pebbles to them to keep them down and secure.

Can't remember what kinds of super glue are aquarium safe. Maybe silicon too, but that would be a longer cure time.

Ive used the gel super glue before for plants but I feel like that wouldn’t be adequate for heavier rocks. But what kind of silicone could I use?

Pretty much any cyanoacrylate (superglue), plain/clear high temp hot glue, and 100% silicone/silicone 1*. Those are all my go to, the hot glue can lose its grip on rocks after a while but it works great to tack stuff together while you put some silicone on it.
