The larger one is a marm coming out of its juvenile stage, the smaller one is still in its juvenile color phase.
I am assuming these are the ones listed at 5-5.5 inches. The smaller one doesn't look no larger than 4 inches (SL) or so. Which doesn't surprise me.
Look nice though but can't tell exactly which variant till older. All Rapps would tell me is they are shipped out of Santarem and they would mature out like the photos he has.
I would definitely like to see the larger specimens before I would commit.
Nice pickup, especially with only 20 shipping.
