I have what I think is a male and female featherfin catfish I've been trying to breed them for the last couple of months. I've had them for about 2 years and they are about 6 to 7 inches. I've been putting them together and taking them apart, depending on aggression in my 46 gallon bow front tank. If anybody tell me looking at their genitalia. If am right about their sex. I have taken a video of the male and female Synodontis Eupterus and is this breeding Behavior or Territorial Behavior? Please watch video and leave your comment.
