I ended up tossing it last night. I used my 30x loupe to exam it, but saw nothing. Sucks because it was expensive and, of course, the freebie green/green hammer that came with it is thriving lol, but such is life!
I think it might have been damaged when I got it or during shipping as it never quite seemed happy in my tank and my other euphyllia are all SO happy

, aussie type included!
