IMO you want to acclimate A.S.A.P but i just got a kole tang and a star today i was supposed to egt them yesterday but the flight was late in indianna and couldnt be deleivred so the fish where in a bag for 22 hours, and they are both still very healthy and active right now after i just got done acclimating.
o.k so my point is they will be fine, but acclimate as soon as you possibly can
