I was getting some bugs for my girl, she's an adult maybe on the smaller side. Saw some roaches but I couldn't get a good look at them there, they're advertised as Giant Islanders. I fed one to her, it started hissing which I didn't expect. I know hissers tend to be a bit of a concern for them. She ate it nonetheless and is fine and dandy though she took a while getting it down. I have one more roach, will it be any concern feeding it to her? It's maybe 2'0 inches in size.
