Is that a whip fin in there with it? I love the whip fin. I lost mine because I added an aggressive anthias and replaced it with a Mccoscker's because it was available at the time. I just added a Dusky, and although the Mccoscker's is getting along with the Dusky and hanging out and swimming together, the Mcoscker's doesn't fill the hole that the Whip fin left.
I've had mine for months now and looks like the photo above. Almost a red color with barely any dark tones. Yet I see another photo here where they're darker. Mine is about 2.5 inches. I assume the darker colors come out with age and as they approach the terminal male colors. How long before yours got darker?
