Does anybody know how long an acropora frag can survive without light? I am leaving for a short family vacation in a little while and completely forgot to set up the timer. Lights will not be on from Saturday-Sunday, so 48 hours. I am returning Sunday night so I may be able to turn on the lights for a couple hours. I could also see if the house sitter could try and turn on the lights while she is here. This is my first and only acro and it seems to be doing well so I would be pretty upset if I returned to find out its dying.
