I have a couple WC Senegal bichirs and I’m trying to determine if there behavior is mating or aggression. One keeps biting and nipping the other and it damaged it’s eye. It’s now in a hospital tank. I will probably sell one if they’re both male, the seller I bought from said they were male n female
I also have a Delhezi and the aggressive sen doesn’t both that or any other fish, just the other sen
Here’s some pics of their anal fin area, the darker sen is the aggressor
Thanks for any help
