The LFS owner told me he went as far as to autopsy some of these deceased angels to check for intestinal parasites. Nothing. They're not sure why it's happening. He did say the local breeder is very particular. His theory is the breeder's tanks may be "too sterile"? He gave me the option of waiting, and he'd give me another angel once they're sure everything is A-OK, or just refund the cash. I took the cash and wound-up spending most of it right back at the store anyway.Kinda sucky, but kinda cool, too. It's good of them to do the refund like that.
Got two Siamese Algae eaters and a large potted wisteria plant for my 55g.
