I was able to get them to 23 days consitenty but couldn't pass that point. This was back when BRList was alive and MMoe was active there, I was thrilled and honerd to get personal e-mail from him saying there was something about that 23 day mark...
I know others have done far better but I gave up, too many concussions from beating my head against the wall. Besides, 20 day old lysmata larvae make great baby seahorse food
