just got a 6" alligator gar. he's in an 80 gallon (3x2x2) with a 5" rtc. i got him a week ago and i have only actually seen him eat 2 minnows. i don't think it is possible that my rtc has eaten all the feeders that have gone missing since i feed him lots of pellets and frozen krill. are there signs to look for that my gar is not getting enough food? he seems to be a pretty terrible hunter. he generally does not even go near the minnows. is there a different type of food that i can give him that is easier to catch? he swims away from any frozen food i try to give him. are live crickets and mealworms ok to try?
