I posted back in December that my female Rainbow Cichlid and male Firemouth Cichlid had mated. Since that time he has been harassing her off and on. Over the last couple of weeks it has gotten more intense though. Usually she swims away and hides, but sometimes (like tonight) she presents her side and they act like they did when they wound up having eggs. Even when he chases her, it seems mostly like bluffing. I have never seen him actually cause physical harm. He will charge her and at the last second pull up and just bump her in the side. Which brings me to my question. I noticed she had a tiny mark about 1/4" behind her right eye last night. It was no worse or better this morning when I did the water change. This evening, I came home to what appears to be both of her sides injured. The right side is a little worse with the first part of the injury deeper. It appears to me they have been scraped against something in the tank, possibly when he was chasing her. I don't think an illness would come on this quickly or be this symmetrical, nor does it appear to be a fish attack. I would like some other opinions please. Thank you in advance.
