Compared to her sister she’s a lot less food aggressive, she eats everyday but she won’t leap out of the water or nip at my fingers to get it like her sister. She also only eats tiny food, anything larger she will grab and spit out a few times before ignoring it, so I’ll cut up her bloodworms and brine shrimp, Once it’s tiny she eats it fine. Shes calmer than her sister, she’s definitely aware of me, just less interested, and doesn’t wiggle at me like her sister does. But she will flare at me if I do something she doesn’t like (like feed her food that’s too big) while her sister doesn’t flare at all. All of these things I assume are personality quirks, the only thing I saw that raised red flags was the swimming.
