He should be able to catch them in that container. Throw some in at night.. mine are doing great. They all are eating and poopin. My room temp is 77,and humidity is 60. I mist one side of area. That's great your temp is all year . Maybe if you put the container in the glass tank and heat the tank with a heating pad or a 25 watt bulb on top . The temp for him has to be 80,with 65% humidity. Get a temp/ humidity reader and put it in the tank so you know. My frog room is kept at 77-79/50-70%.
