Guess SA is your local fish store. Mine too (and AS).. I saw this group last weekend and told the people there they had to break them up immediately if they didn't want to lose most of them. As stated, they are Sanchezis but they just have them marked as Red Throat Piranhas. They definitely need to be kept solo but the one guy told me they "probably didn't have enough space". Unfortunate, I'm sure there have been casualties already.
