Hi Rudy,
My Henleis have looked like this, two females after the male had been mating with them. During the pregnancy this discoloring comes and goes. Discoloring often has to do with stress, but I also think hormones tend to have influence on the coloring.
Once my big male went pale for a week, till this day I don't know why, guessing I would say it was the water or the food.
If a ray is still eating it will live, when it stops youd better get worried!
Keep us updated, greeings Mark
p.s. I really like that big mother... huge dots
