Wow, where did you find one of those?! Unusual doesn't touch it, LemonLemon, that is a glorious fish. Sorry to hear about the color loss..
BTW, that Arabian is insane! Too bad they are one of the more belligerent Dotties..
Sadly, recently, I've had a run of bad luck with Pseudochromids. I'm not sure why, though perhaps I should have a long heart-to-heart with my T. lunare Wrasse. Could just be the natural enmity between those two groups of fish. But actually, my bad luck with them started about the time of my 36 Gallon tank crash, long before the lunare was around. When my very beloved Sankey's Dottyback vanished. That one was pretty peaceful for a Dotty..
My last try was a Diadem, it vanished too.
Sincerely,
Matthew
