Uhm... This is my first time to post here in this website. I just want to consult my venustus. i only have 1 venustus and it is a female. Every month she is alaways holding but im so curious who is the father. I housed her in a 55g tank and she is the only fish there. I tried to put male venustus but she is always killing them. What should I do? why is she always holding even though she is the only fish at my aquarium? :-?
