Hey Roger! Those were sold some time ago, but I will have at least one sharp mini colony available at the swap. It's a great piece because it is about three inches long by two and a half inches wide with about forty or fifty spikes all the same length, facing straight up. It's already tabling before it starts! Should grow into a beautiful centerpiece in anyone's tank. The Red Planet is one of the sharpest and sturdiest acros out there, in my book.
