After I turned the lights off everyone calmed down. Like I said, my experience is only with live bearers and mouth brooders. I read up a bunch on Rams last night though. And just as I discovered, after no make cane around she abondoned the nest, and the rest of the fish had a feeding frenzy, kinda sad. But no one died, or got eaten.
I wonder if the two females fighting off intruders together was a unique thing. I'll try to get it on film if it happens again.
Thanks everyone.
