Default Albino/leucistic UE R. sirensis?

So, I acquired a group of Understory R. sirensis (formerly R. lamasi) from Pumilio Doug, and they produced their first clutch around 4.17.12. One of the tadpoles is very dark and appears normal, while the other is mostly colorless, only the eyes are black and the chromatophores are reflective. Under the binocular scope, you can see the blood cells coursing around its body. See photos, attached.

I have had some very lightly-colored R. amazonicus "Iquitos" tadpoles that eventually colored-up before morphing. This tadpoles has remained colorless as it is going through metamorphosis now.

I am wondering if anyone else has seen this in the UE frogs from Mark Pepper.

Thanks, Richard.

Richard, it is not uncommon in the Understory Green Sirensis line. In a personal conversation with Patrick at Saurian, he has seen it. Speaking with a friend of mine who does a lot of purchases through Mark Pepper, I was told that Mark currently has 4 breeding groups. 2 groups produce them and 2 do not.
Mark Pulawski has produced at least one and his did NOT come from me. http://www.dendroboard.com/forum/mem...en-lamasi.html
Mine have produced several but this is out of...quite a few froglets.
Here are a couple threads with pics. http://www.dendroboard.com/forum/fro...-sirensis.html Then this thread goes into some detail regarding leucistic, Amelanistic, or what. (scroll down towards the bottom) http://www.dendroboard.com/forum/mem...-sirensis.html
I am tending to follow InnoEcto's input on this as they have a lot of experience with this sort of thing from their snake and lizard breeding.

Their eyes do appear dark, but if you look closely you will see that they do have red pupils.

They are a color morph similar to the 'Chocolate' Leucomelas, which is also a T+ albino.
In speaking with some of my peers on the board, it sounds like it is OK to breed ONE of these back to a normal one (preferably from a non related group), but it is NOT ok to breed one Xanthic Albino to another Xanthic Albino, because obviously this would be selectively breeding for the trait.
As I mentioned, I get one now and then, in fact, we have one approaching 2 months right now. When I do morph one out, I will only sell ONE Xanthic Albino per customer. I insist upon their agreement not to keep more than one Xanthic per viv. i.e. They must agree to simply enjoy the occasional oddball and NOT to breed two Xanthics together.

Oh yeah, one last thing. A gentleman who is not a "teem player" was trying to collect multiples of these. I strongly suspect the desire to selectively breed them for the trait. My decision was NOT to sell any to him.

Thanks for the info, Doug. I agree completely about keeping these in a mixed group with the type frogs, but it is exciting to see them pop up every now and again!

So this frog, attributed to Mark Pulawski in the R. lamasi thread, looks very much like my metamorph.

Lucky for the little metamorph that I am vegan.

I transfer all my tadpoles with that spoon (350-500 every week). I am the fastest tadpole wrangler East of the Rockies!

Hey Richard, here are some pics of our most recent, Xanthic Albino Sirensis. The ones we have produced all look very similar to each other. I'm sure yours will look the same as he grows.
