I have a pair of garters in one cage, and they both take to flopping fish like thier hypnotised, but the female wont take a pinky for anything. I've even rubbed the fish against the pinking and she's struck it, latched, and then let go. I was thinking about using trout to rub on the pinkies. I want to know what an appropriate trout + pinking sizing should be. I don't want to over feed.
