There are a lot of frog owners that feed out side the tank. Make sure to still use tongs and not fingers. If you use fingers they will incorperate them as food also.
Always using tongs, I take him eating though outside of the tank with me right there as being comfortable with me right? also he pooped like 5minutes later in his enclosure and it was literally half a digested nightcrawler? guess they don't chew very well lol
