Yeah being around the tank more can help as they get older they will recognize you and not be so skittish, mine would only get a little bit skittish when I cleaned the glass with the magnet but eventually got used to it, but still every once in a while they jump and hit there head but very rare they are smart and know what will happen when they get bigger, sinc I got an overflow lowering the water is not an option, but with aros and good water quality they heal and grow back scales in just days, plus add a little aquarium salt
