I couldn't find any good pictures of what a cortez looks like but thats probably what they are if thats what you all say.
Yes, I got them from my LFS, they had a ton in stock and were a good price too.
I had some bigger shells in the tank and within an hour one of the bigger guys found a different shell. I was so mad I didn't get to see him make the switch, I really want to see one move into another shell.
How big do these hermits get? Will they stay small or keep on growing?
