As I posted, my gar ate a thawed silverside yesterday. Today it took seconds and he took it right away. About the starving question (and I'd really like to hear more from the experts here), My research suggested that a bigger gar could go a week without feeding with no discomfort. My gar took the thawed fish on day six after all the feeders had been eaten, which is good, because I would have put feeders in the next day if he hadn't. I assumed that it took him that long to get really hungry. I just hope I wasn't inadvertently being cruel. Anyway, it is clear that he will eat a large thawed fish every day now. He is the most aggressive thing in the tank, so I don't see anyone interfering from here on out.
