Lotus they are a captive bred true perc pair that I just got. My other pair were sold with my 75g set up, I didn't have the heart to seperate them from their host. These guys will find something to host in and I am thinking it may be the duncans, though who knows it took my other pair over 2 years to find the nem. I know this though, I am not putting an anemone in this tank, it is too small and they tend to take over.
