no, it's manzanita branches. I got a huge bunch of them for about 15 bucks. they had the option of sandblasted and non sandblasted, and I opted for the non sandblasted... over the first month, the bark got fuzzy white, deteriorated, and fell off. the otos and shrimp seemed to love it in places without the fuzz. once the bark was gone I was left with brightly colored branches for a few weeks, and now they've turned dark brown again. next time around I'd just go with the sandblasted ones... they weren't much more expensive.
