Tincman Herps new NaturalRose product has nearly twice the amount of natural Astaxanthin as the original product we sold.. Carotenoids do a lot for amphibians and other Herps. Not only does the pigment enhance and bring out color in them, but studies have shown that Carotenoids play a role in maintaining a healthy metabolism & even enhancing breeding results. Tincman Herps adds over 3% to all Fly media in conjunction with other carotenoid and fruit pigment, but you can also dust your insects with it for good results. using it more often in a lower percentage (ie. 20% NaturalRose/80% Dendrocare every dusting) has been proven more effective then using the carotenoid straight out weekly only.
