okay so my female motoro, the healthiest ray i have ever owned. Last night i woke up to her chasing the marble male, biting his disk a little....idk i think the male is an old ray honestly and just doesn't want to breed and the female is trying to lead the way to the "bed room" any thoughts. it only happens at night when all the lights r off and im sleeping. i was up last night tho so i witnessed it
