I was at the petsmart from where I've gotten all my other unusual guys, and came across a truly strange combo: a pyrite [aka "fools gold"], vivid lavender, and red crowntail male. The pyrite was a copper, but with a definite golden tinge to it. It was really something to see!
However, he had some other qualities that were really something to see as well--and not in a good way. He was rather old-looking, very lethargic, had really bad scale shape, and I think a case of SBD. Most dissuading, though, was a lump or bulge on his body that was about the size of a pencil's lead tip near where his tail and anal fins meet. To use a more unflattering description: he's "tore up from the floor up".
I'm still debating on getting him though. Despite all his flaws, his colors were truly unique (I think--never heard of pyrite being a color). Could it simply be something a little TLC could fix (in the case of SBD and rump-lump)? Has anyone seen that pyrite coloring before?
