Is Fimo polymer "clay" fish safe

People keep looking for non-fired clays that are tank safe. To the best of my knowledge there aren't any.
But there are low temperature fired compounds.

Does any one have grade "proof" that Fimo or Sculpey brand poly compounds are fish and tank safe?

Here read that Sixwing used Sculpey clay in his tank.

Is to make something or for substrate? For laterite substrate is clay made for aquariums.

I've always wanted to try and make some caves. Sculpey looks interesting. I wonder which one he uses.

here you go

Seems like the polymer clays contains PVC, and some form of Phthalate plasticizers. It's what makes the play soft and is petroleum bases.

It appears that we have a usable product.
I don't think I'll be making Lxxx pleco caves out of it yet, ceramic is a lot cheaper.
