What about this one in the center of the photo? We have recognized it as M.hippuroides for many years as well as many aquarists from Japan. Meanwhile we recognize the one on the left side as M.matogrossense, while it is identified by your website (as well as Tropical 's database) asM. Tuberculatum, Are they indicating the same one?
The red variant of M. mattogrossense is now being called M. tuberculatum. The green variety is still called M. mattogrossense. The change was made several years ago, and all of the newer texts recognize this change.
