Sun coral fading color

[GrUmPy fAlCo]

I just purchased an orange suncoral about 3 weeks ago. I have been feeding it about 3 to 4 times a week with krill. it was a nice bright orange when purchased. i have it in the middle of my 75 gallon at the bottom of the tank. Water parameters are up to par. Nitrates can get up to 5 on red sea test kit, but not higher.I do weekly 15 gallon water changes. Still eats all the time and yellow tentacles are bright and numerous. Anythoughts would be helpful.

is it in the light or under a ledge? have you tried feeding them something else?

Middle of the tank. Not directly under a light but not under a ledge either. Mysis but the one I get from the lfs are small and difficult to put into thier tentacles.

Mysis is what I feed mine all the time with no problem.
