I just got a piece of driftwood for my tank. The owner of the fish store I got the piece from said it was tank-ready so just to be safe i washed it off for 45minutes... There is a faint smell of coconut tanning oil coming from the wood. I'm not sure exactly what kind of driftwood it is but I was wondering if any there are any types that smell like this naturally or if this is unnatural and if i should take it out of the tank.
