It's a piece of purple acro. Not sure the specific variation though. It was salvaged from a crashed reef tank and I picked it up for $5 for that whole piece, thus why part of it is dead/dying. Yeah I did end up moving it to the top of the tank after these picture were taken, I had just kept forgetting to today til I took these. It's got purple tips or polyps or whatever you wanna call the pieces that come out from the hard nubby parts. I may have to frag it into 3 pieces and cut out the dying parts though. Gotta keep an eye on it and see if the death is progressing further or if it is staying put where it is.
And nope on the camera price. Go lower.
