This ceramic skull in on sale at Hobby Lobby for $11.
It is over 8" long and 6" high. I am trying to gather things for my tank setup.
Question: Do I need to seal it?
If so, with what?
Can I use acrylic spray paint?
I'm sure it'll eventually break down unless you can preserve it. Pond Armor (100% aquarium safe) should work as long as you get a good coat over the whole thing. I used Pond Armor on my 450gal center piece Casuarina tree root section as it is a unique beautiful piece. One of the best things I ever did.
