This makes perfect sense. Palometas is from the family Carangidae and these guys are closely related to jacks. They are rarely seen in the home aquarium trade, and most definitely pack a punch with their little razor-like teeth. Looking at photos online I could why people would confuse them with angelfish, though marine angelfish are typically brightly colored. Palometas should not be taken lightly, and it's a really good idea to get out of the water if someone around you experiences a nip or a bite. Feeding them only causes them to congregate in shoals which of course will lead to more bites.
