I emailed the person on CL with (7) 6" pygos (fairly sure RBP) in a 40, asking if they'd be willing to sell me a pair for Peek to shoal with. They won't split the shoal b/c they want them all gone, and their petstore told them you HAVE to grow all fish in a shoal together or they'll kill each other.... I said they'd have better luck posting them here, but I'm sure others will ask to split the group because their tank isn't big enough... Urgh, so the hunt continues....
