Ruin decor.

Picked these up from petsmart. For a $1 each. Their made by national geographic. I believe their made of poly resin. No bright paints on them.

 

I know it's not natural. But I wanted to grow GSP and other encrusting corals on them. (On her hair actually) Without adding more live rock.

 

I don't mind them fading. Or coralline/algae. It'll add more to the look. But will the paint poison the water?

Shouldn't. maybe it's food grade paint but I can't find anything on Google.

It will say safe for saltwater use on them.

 

Its not just the paint that could be an issue but the plastic used as well.

Haha, kind of a chia pet for your reef tank. It would likely be hard to confine the GSP to the hair (let alone the plastic sculpture); but then again, it might look more interesting fully encrusted in GSP.

It would most likely be fine but if youre worried about it you could throw it in a small cheap tank and heat it up higher than normal and test for phosphates to rule that out. I guess take a sip to find out if the paint is toxic or not.
