well... while i was trying to hack 99% of my blue xenia down i was cutting one of the pieces of rock and smelled a funny smell... decided to chip away at the rock to see what it was and i found a tree stump inside of the piece of liverock! seems very off that this would happen.... but it was in my tank like this. i wonder how it could of got like that? at first i thought it was a bone but i am 99% sure it is a tree stump.

here is a picture:

i outlined it in red to show you where the actual piece is and that there is liverock still attached to it:
