unexpected color changes

[Magnum Man]

admittedly my Hillstream tank can be challenging to tell who is who sometimes, with the large variety of species, and the fact that many of what I have aren't scientifically described, throw in , most are received as juvinal... but I'm pretty sure I just saw a "bloody mary" Gastromyzon sp, that typically have red spots going down their back, like pictured below...

but this one today had bright white spots instead of the red patches... I hadn't noticed that before... most coming here ( I have several ) have come in tiny, and looked like the picture above... recently I have found some pictures with more variety in coloration...

I'm wondering how much color change I may see , on these fish, as they mature???

Chris Lukhaup makes always such great such shots of fish. We know eachother personally and we do meet up from time to time. And he's always so concerned about my health issues.

I've got some hillstream loaches overhere as well but not as nice colored as these...
