Pups smoothie or tope??

can anyone give me tips on telling the difference between tope and smoothie pups, lately ive caught many pups, the starry ones obviousy are smoothies and some have a fine set of teeth with dark or black tips on tail fin, probly easy question.
thanks in advance

there are 2 obvious ways to check between them when they are that small..
firstly, pup tope have small teeth like loads of small needles, whereas smoothies have the pads.
the other is the snout, on pup tope it is much longer and lighter in colour than the smoothie.

if your lucky enough to catch one of each around the same time you will notice a few other slight differences as well
