They're pretty difficult to keep apparently...needing at least a 12" sandbed. They get infections in their tails pretty easily and can't burrow, then die.
I have wanted them for YEARS...Randall had some at Aquatic Specialists and that's when I started researching them. Things may be different now than previously...maybe their survivorship is better these days?
If you get some, I'm totally gonna want to come see them.
