The white male in video clip is offspring of Marlboro swordtail, however its red pigmentation decreased over the time and eventually disappeared; at the moment, he is totally white with a horizontal light neon blue along his body. I haven't got any knowledge about Marlboro swordtail, but so far I heard that it's normal for Marlboro swordtail to partial or totally lose its red pigmentation over developmental stages. My questions are: - Is red pigmentation fixed when a red swordtail is born or the pigmentation is produced consecutively during its lifespan to maintain the red color? - Is there a gene factor that suppress the red pigmentation production which caused the loss of red pigmentation (LP) in Marlboro swordtail? - Will LP a dominant or recessive inheritance factor? - What happen if I cross this Marlboro male to normal red female or to a albino red female? Advantages: - This male is active breeder, he loves chasing after a huge size red female. Disadvantages: - This strain I collected from a farm in FL. He was shipped together with his siblings (males and females) but all of them suffered heavy fungus on the way to my place. Only him recovered and survived which is showing his good resistance, but not sure if the past disease had any effect on his fertility. He's the smallest swordtail comparing to his siblings. Breeding model: Due to limited time and space for my hobby, my swordtail fries are often kept in common tanks categorized by size range during their developmental stages. This avoid small bodies from starving due to food competition. Culling process usually goes along with each stage, thus it make my tracking list much easier for record and observation. This breeding scheme is to observe if LP has any effect on Albino red. Next step: - I will cross this male to normal red female in another project. - And his offspring with Albino red female in this project will be back cross with the father and to its sibling to see if the effect get stronger (double dose or triple dose, maybe)
