Thanks, Ed! I kinda think the shipping process may have broken their bond, sadly... the male has begun kinda chasing the female a lot. I'll monitor it, and if necessary, try separating them and repairing them in a week or so if things don't improve. May try raising the tank temp a bit as well. But its just day 1 right now, so I'll wait a few days and see how it develops. Nonetheless, they are stunning!
