I try 3 different ways at differnt times just to see if I can tell a difference..
1. Through the lips just a little deep but not so much as to kill them..
2. behind the dorsal... find the balance point so they hand horizontal..
3. in the tail.. makes them wiggle like through the lips but other way ..
I'm a noob so if some spert comes on with something better do what they say..
