Hand painted stones

My son painted a large stone at nursery the other day and he wants to put it in the tank so I was wondering it if would be ok if I varnished it first? If not I won’t use it, I just thought I’d ask before we have unhappy fish

Not 100% sure but I'd doubt it.

In my opinion it is not worth the risk. It will ruin your water chemistry and poison the fish.

Even if you tracked down a water proof one, I would be worried about slow leaching over time. Why not just place it next to the tank or maybe on a stand behind the tank to be seen through the glass?
