Its a Pastel Lesser...
Quality is so so...
With the real nice Pastel Lessers, theres no guessing, the difference is night and day..
Heres a pic of my breeder male, from just shortly after I produced him in 09, pictured next to a regular Lesser sibling, no guessing here!
Here is that same male, next to another sibling, but this sibling is also a Pastel Lesser... You can see how the one one the left might be harder to distinguish from a regular Lesser, so I sent that one to a breeder out west, and kept the the other one to further my selective breeding projects..
My guess is that yours looked similar to the one on the left above as a youngster..
I should try to get a pic of him these days breeding some morph girls...still no doubt as to what he is at all! lol
