Little black tube that sprout satellite dishes along the edges? Are we talking about along the skeleton? If so, those are probably just mini-feather dusters that are growing on the dead skeleton. If you're saying these things are coming out of the living tissue, then a picture would be interesting... doesn't sound like something normal.
As far as tentacles, when they show themselves, it will be along the border between the outer "striped" tissue and the smoother "inner" tissue. They'll usually come out if it senses a lot of food in the water, or when the lights are out. Mine doesn't do it every night, but normally at least every other night.
As far as it coloring back up, it could take months to regain its color again.
A question for the group... has anyone encountered an artificially dyed Open Brain? With how blue that was to start with, I wonder if that could be a possibility? I know it's done with cup corals and some soft corals, but I don't think I've heard about it being done to Trachyphillia. Just thinking out loud... DyedCorals
