One of my LFS carries grapevine (not a petstore that carries reptile products). I have some in my tanks. It does ok with plecos and snails to eat at the softest parts. It also looks really cool. However, unlike hard woods, when you soak it to sink it - it grows this icky white slime and has a rotted smell. Again, with plecos and snails, it gets better. Probably easiest to avoid using it though.
