Larry-
Are the Berghia primarily active at night? I was so excited a few days ago when I spotted one of the Berghia at the opposite end of the tank from which they'd been introduced (won three at the meeting at StephenA's house). It was during one of my "night watch" sessions. Also, will they breed successfully in a reef tank, or does that have to be in a tank specifically for that purpose?
