I feel it might be a female. I put her in my 125 with my Oscar and 2 firemouths since I came to the conclusion she’s probably a girl. And they’ve only been in the tank together for about 2 hours but she’s not even chasing the firemouths let alone my Oscar. If anything the Oscar was showing a tad bit of aggressiveness but no biting just mouth and gill flaring to show he’s boss, and she’s bigger then him and acts like he’s not there. The flowerhorns about 7 inch, and the Oscar is about 6 while my firemouths are tiny, about 2.5 inches each. Based on just the temperament I’ve come to the conclusion it’s a girl? What do you guys think?
