How long ago did you put them in the tank? They spent a lot of time hiding in the first 5-7 days I had them in my 55g and I have a lot of plant.
After that - they have periods of high activity. The males will try to figure out who is the alpha - lots of chasing and the occasional "lip wrestling" where they will lock lips. Even with all of that, I can come in and find them all semi-nose down just relaxing.
