    Hi Everyone, I am new to this forum but have read things over the past few months in researching apistogramma. I recently bought two pairs, or so I thought, of wild apistogramma cacatuoides from David Soares. I need help with the sexing because I believe I may have received 3 males. I will attach a photo of the fish I am unsure of and the others, any help would be greatly appreciated.

    Top pic is a male I believe
    2nd to the top is a female (more yellow)
    3rd is a male
    4th/bottom I am not sure of. I thought it was a female but it chases the yellow female around a lot and is acting very similar to the males.

    I'd need better photos and know the size of the fish first.

    Sorry it is very hard to get some quality pictures. I guess my biggest question is this video mating behavior or just aggression? This is my dominant male. He chases every other fish (1 male and 2 females) around the tank non stop. He seems to be “showing off” but at the same time he is attacking this female relentlessly. I understand the aggression towards the other male because he is trying to establish territory and dominance, but is this something I should be worried about or a good thing? I asked David Soares and he said these are wild fish and aggression is normal but just wanted to show the actual footage

    Males can also be aggressive to females that are not ready to spawn.

    Do you think it would be smart to remove any fish from the tank or will the aggression lessen over time?

    I have two males and two females in a 40 gallon breeder, I didn’t think that would be too small of a tank but maybe I’m wrong?

    It really depends on how the tank is decorated. It needs many visual barriers and boundaries.
