My six line wrasse has suddenly (within the last week) started chasing my mandarin around biting at him. The six line is pretty much all over the tank all the time so I don't think he has a "territory" for the mandarin to invade. I've heard stories of six lines being aggressive but mine has never bothered anything until now. Could he just be getting meaner as he gets older? I've had the mandarin for 9 months and the six line for about 6.
