a few rbt tank questions

[spires33]

hi. i am wanting to make a hut. i am wondering if there is anything in natural clay that would hurt them. i know probably there is nothing, but better safe than sorry right?
and also i am wanting a themed tank it wont make them stressed as long as all there requirements are met right? (again better safe than sorry)
And also what tank size could i use to put fish in and whether i should at all because i have heard of people doing it just fine but i doubt its ok. but it would be cool . And i do have a reptile filter if that would make a difference.
and what plants with no light requirement could i put in there.

looking mainly for vines thank you

Natural clay is well, naturally inert. As long as it air-dried well then pre-soaked in water before using it with your fbts then it is just fine. Try getting some photos or small-leaved philodendrons. They are second to none in thriving under low light
