Very cool Robertsoni makes me wish I picked up the one the LFS had in, still might go back and grab him. He was 6-7" and I really didnt know much about them but after doing the research I would like one.
Bringing up a very old post. My Robertsoni just kicked it. Had him a long time. Never got to measure him until today unfortunately. Surprised to see he was a little over 11" He was just over 11" long. He was just a little bigger than the diameter of my 5 gallon bucket which is 11".
