I brought him home about 4 days ago and alread he has settled in and been eating crickes. a few questions i have about him are is it normal for me to be tweezer feeding him fish and is it bollocks that he will not regress down the food chain of food from fish to crickets? someone at my work told me that and i dont believe em. He has an intresting bark and croak. Although i have only had to provoke him to croak... Will there be a time that he will croak on his own? is there a sound wav i can loop ...
