Glad to hear your rays are settling in.
They look a nice clean pair of rays given they are wild collected, they are not however what we on here would consider as ultra high quality, they could still change for the better as many Marbles often do but these are no longer pups so I would say any further changes will be slight.
As Alan DBjunkie said, you will have to monitor over time to establish if this is indeed a smaller strain of motoro, for me they do not look typical mini/midget Marbles but hey! they could still be, its a waiting game, the species is massively variable regarding patterns.
All the best with them.
