My heros species are all relatively "active." IME there really aren't very many active species like a dog would be or something, but there are some that will be out more than others. Both of the heros species I have don't hide very often and I will see them wandering sometimes. Plus they are impressive in size and beauty;P!!
Our alternans is rarely if ever out during the day, it spends its time burrowed in the substrate! It is only around 4-5 inch at the moment though, im hoping it gets bolder as it settles in, only had it a week or so.
