Thanks for posting the pics and videos of your Rams. I am following a similar evolution as you - mine seem to be getting used to my ugly mug coming around, so they are not quite as shy 9 days in. I am also trying to figure out the sex of mine...not much luck so far. But they are still young.
Have you seen yours do any breeding yet?
Have your shrimp survived the tank with the Cichlids, or did they become food?
