I don't have any Winemilleri, yet. The Tapajos are conspecific aggressive but not overly. The Brasiliensis were fine with each other until a pair formed but so far only chasing the 3rd wheel away. Minor aggression towards other tank mates to ensure they stay away from fry. I will be moving the G.B. to a 260g once it is set up.Are there pictures of winemilleri and feedback on their behavior ? I skimmed the thread but didn't see any.
