Hope this helps!

Cliff, you da man!

I'm looking for that thread now. You say it can take up to 2 1/2 years to show their FINAL color. The change to that color BEGINS to change as early as the first shed, yes? But to my understanding, the transformation becomes quicker, and therefore more noticeable at about the one year mark, is that also correct?

I presume then it is also metachrosis that is responsible for the day/night change in the Dominican Red Mountain Boa as well?

Hey Cliff, I found that thread but it's too old to still contain the pictures. Might you still have them?

wow, those red mountain boas are sweet!
Your new girls are gorgeous strutter,

Thank you. Still trying to let them acclimate but it's tough leaving them to hide in their enclosures!

Stutter, I forgot and apologize -- that picture hosting site went down for good. However, if you look at the Living Gems Facebook page, there is an album with those same picts.

Yes, color change begins with the first shed, and is usually most intense at the beginning, tapering off as time goes on. However, I've also had Brazilians that started strong, went down in appearance, and then came back up...so it's hard to tell. You usually have a pretty good idea by 18 months though; the time after that is mostly finishing, and some snakes don't chnage much at all.

Sorry, can't help with the Dominican Reds -- not familiar.

Let me know if I can help further!
