The aquasd are undeniably pretty, but not what's listed on zoaid.com. The ones on zoaid are some type of protopalythoa whereas the ones listed on aquasd are PEs. Those are nice as well Xiong but also not what I would call Big Bangs, those look more like purple death morphs, nice though! Those are the closest yet though, I think the big bangs are more of a pastel coloration.
You know looking at the pics it could just be the lighting, you might be right Xiong! Those may just be what I've been looking for.
