The different varients in the Lima's are just from different river systems. 15" is not that hard to hit on Lima's its the 18+ inch size thats tough to find unless you have a public aquarium or a uber large personal tank. Here's a pic of a 15-16" one for sale at the LFS near me, a 14" one from a different LFS, and I have one around 12" right now growing a steady 1" a month roughly ~Trent
