I purchased like 10 of these guys on ebay and got more like 20. The guy sent extras to ensure that everything arrived with at least 10 alive. Added a moss ball to my tank and all seems well only see about 10 or so at any given time. They were also very small like 1/4" to 1/2" in size. Have several that are close to an inch and very red now. Bought them almost 3 weeks ago now. Haven't seen any saddled yet but can't wait.
