I think what you wrote is fair and sensible.
When Jello is comfortable, she reacts to the feeding sounds and smells acutely too, not in the same fashion as the hybrids but in her own way by quickly swimming to where the handout usually occurs and assuming a vertical position, mouth just below the water line. That is my expectation for a comfortable apurensis with a healthy appetite, which hadn't at all been exhibited in the last video above.
