Bought a piece of driftwood which was on clearance at petsmart and it had already been in one of their tanks for months so it was cured. Rinsed off with tank water from a water change and put in my new 30 gallon that just finished cycling a few weeks ago. My BN pleco hasn't left it since. I did notice it came with a friend because there was a baby snail crawling up the side tank wall a few hours later. Now that I think about it I don't know if I should be worried about disease or such. It is a dark chocolate colored piece of log. Thoughts?
