wow that looks amazing, love the many branches coming off the main arm. Yeah that looks good to me. I'd throw it in. I have picked 5 pieces all smaller though for my aquariums its alot harder here because most wood seems to rot fast. That piece looks like you bought it.
Haha thanks man. I assume it's from a freshly fallen tree because when you knock on it it sounds like a front door lol. I'm just nervous that since it is a fallen tree there could still be stuff in there I don't want in my water. Although, I've done pretty much all I can do without using chemicals. And so what if there's bugs in there... they'll die anyway
