Just wanted to let you know that my Mustangs arrived this afternoon. After acclimation they were a little quiet but soon began exploring. They haven’t stopped all evening. They seem very happy and friendly.They are not sticking to the no food until tomorrow rule. They are voraciously hunting and snacking on copepods. Seem very pleased with themselves. They are beautiful and we are enjoying them very much. Thanks for your help. Merry Christmas.
