Question about safety of a plant in my vivarium

Hey everyone,

So I’m growing out my crested geckos new vivarium, and things are going great so far, but I did something today and now am wondering if I need to take it back out.

I also have fish tanks, and utilize emergent plants like pothos and spider plants in them. One of my spider plants was looking real good and has a good root system on it, so I pulled it from the water and planted it in my vivarium.

My question is is this going to be safe for my gecko? I know spider plants are fine, but I use fertilizer in my fish tanks so I’m unsure if it would be alright. Only the roots were in the water, and they’re now obviously in the substrate so I’m thinking it should be fine, but I wanted to see if anyone had a definitive answer.

Thanks
