READ!!! I picked up a piece of wood right after the Hurricane Harvey Flood, that I found on the side of a building so it obviously was carried by the flood water. That was like 5 months ago. I used it in my small lizard tank but they payed no attention to it. It hasnt been used in a maybe a month and a half or more and has just sat outside. I don't know what kind of wood it is, so ID would be appreciated. As well, do you think after I water logged it I could put it in my 10 gal or 20 gal fountain? I do not have bleach or anything like that so do not suggest dipping it in their. Any thing I should be worried about. Some pieces of it seemed to come off, meaning a strip of wood/ bark after I was stuffing it down in water. Anything that could be dangerous or something? PS, I don't know if you can tell but in the first pic, on the left side you can see some green. I suppose its algae, but its almost as if it is stained on there. It can't be growth as I'm pretty sure its been there the whole time. THANKS!
