Shell or something with encrusting coralline on it

[BrianAnthony]

Hello, Im just seeing if someone would be willing to mail me a shell or something with coralline on it. I only have a 12g Nano, so I don't need much. I don't have any friends that are in the hobby and I find it hard to justify spending a lot in the retail sector for it. If so, please let me know what you want for it.

I don't have any, but have you checked the LFS? They usually have a lot of rubble with coralline algae.
