Frogspawn dying?

[sharuq1]

My frogspawn is starting to look bad. A lot of the tentacles have gone brown, skinny and less flexible and are no longer fat and healthy looking. (not showing good color)

I don't know why. Everything else in the tank seems fine and the tests don't show any spiking happening. What do I do? What could be wrong? Should I change where he is located? Have not had him very long. (Just jammed in a hole in the rock at the moment because I have not bought reef cement yet) I feed the coralife gumbo to the corals weekly so I don't think it is starving or anything.

Please help
