That's awesome!
I got into the same situation. I have been feeding mine almost daily for 2 weeks. Sometimes he eats, sometimes, he doesn't want it and the peppermint shrimp steal it. He is hiding from the light a little less, but still no color at all. I did get him to eat with the lights on, though.
Hopefully, I will be able to post some before/after pics like yours. Congratulations!
