I got this baby packman last sunday and i keep trying to feed him Dubai roaches. The guy i bought him from said he feed it a pinkie and the frog will sometimes shoot the food with its tongue and just let it sit their until it gets free and leaves and before it just opened its mouth like it was trying to shoot the prey with its tongue.
And he is in a 5 gallon tank and everything perfect he just won't put the effort in to eat.
