Happens with my tibees, OEBTs, and the one CBS. When I had a colony of over 20 OEBTs, it didn't happen with all of them, just the larger females which tended to have the brownish hues on their tails (3 separate sources on those OEBTS) The OEBTs in there now are Germans from Nick's source, not going to be any close wild tiger or super tiger genes in there I wouldn't think. The CBS female has the brown tints but not my males, granted she is my only CBS female. It doesn't happen with all my tibees either, just the ones with the brownish hues on the tail (which is generally the females but I do have a male or two with it).
And of course, based on other posts here there are more than just tigers that have the brown/orange tint to the molts
Huh! I didn't realize this wasn't common knowledge, lol. For me it's plain as night and day whether a CBS or a neo has molted in my tank. Interesting that that's not true for everyone. And yes, I mean in the same tank, same conditions.
