"Hypo" is short for Hypo-Melanistic, meaning reduced or lack of black pigmentation, which leaves mostly the tan and pink colors. "Salmon" is used because of the resemblance to the pink/grey coloring of the fish. I can't remember if they are interchangeable terms or not, but I believe Hypo is more pink/tan, whereas Salmon is more pink/grey. "Het Sunglow" means that it carries the Sunglow gene, but it is not a visible trait. I am guessing that the "25% Other" means that one of the parents is an offspring of a Hog X Sunglow pairing.
