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.
Where did you get so many branches for 15$? I was about to place an order from http://www.manzanita.com/
I'm not entirely sure what their prices are, but I'd prefer the cheapest option available.
I got them from a vendor in the flower district in nYc... they were in a bin out in front of the store, massive selection. I think it was on 28th street.
Too bad I'm a bit far from NY. Maybe I can find some locally. I haven't even considered looking till now.
If that fails I'll just go with manzanita.com. I hear good things about them.
