So a friend if mine and I swap frags back and forth, therefore we each pretty much have the same stuff the other one does. The weird part is when I find out that if one of my corals is doing bad or has kicked the bucket, most likely the same one in his tank has either already died or is doing poorly as well. Could be something we traded a year ago as well. Seems to happen mostly with softies, but either way it just seems insane. Can local factors cause this, like possibly something in the air or barometric changes, don’t really know what’s up….
