I'm not really familiar with Zoids but if they're pre-manufactured plastic toys, I'd try to get in contact with the manufacturer (although I understand TOMY no longer makes them, or something?) and ask about the type of plastic they use. If they're the type of model that you need to glue together, I wouldn't do it. The glue is likely toxic and would come apart underwater.
But yeah, generally I try to stick with decor manufactured specifically for aquarium use or natural decor (rocks, driftwood, plants, etc.).
Yeah, tomy and hasbro no longer manufacture them, they are models that don't involve any glue, I am almost tempted to contact the makers of the high end master model kits, as those are still regularly in production.
I know theres not much an aquarium test kit would help me with testing, but wasn't sure if there was maybe something specific I could get a test kit for.
Guess I'll see if I can get in contact with any manufacturers.
