Yup, me again. So, what about a squirrel skeleton? It died of a broken back, was picked up by me literally minutes after it died, and spent 10 days underground. After that, it was dug up, soaked in a hydrogen peroxide solution, rinsed, and partially assembled using SuperGlue.
What would I have to do to make sure it's aquarium safe? I have a tree-looking piece of driftwood in my 65, and I think a squirrel skeleton is just what it needs. Yeah, I'm weird for wanting bones in my tank.
