why discus fight at night?

Six in a 75 should be fine, but yeah, more plants never hurt. Let us know how it goes with the changes.

Mine are still being little jerks at night, but I'm gonna try feeding them later like Bijack said. Maybe they're just bored.

Update: added some floating plants and they're way calmer now. Still some bickering, but not as bad. Thanks for the advice!
