What do you mean by it pouting and being emo? I mean mine definitely has a personality and is by far my most reactive fish, but he generally just seems hungry and/or bored. It's kind of adorable that he seems to have a set bedtime at which he just completely disappears (he used to burrow but haven't seen it in a while) and boom, he's there again in the morning. Nothing seems to really phase him. When I first picked him up, I naively tried including him in my large predator community, and of course he just attacked things. But despite being constantly nipped at by an oscar he never showed any signs of injury or mental distress, and actually would follow the poor oscar around everywhere harassing it. Even during water changes he only gets out of the way enough to not get bumped into by the tubes and brushes, as he seems intrigued by what's going on and wants to see it. Despite their reputation, this guy is one hardy little fish.
At this point I can still feed him by hand, but I'm pretty sure that the only reason this works is that frozen silversides taste better than my finger.
