They are rather shy aren't they! LOL
I have two frogs I found I swear are bullgrogs. I keep waiting for they to do the loud deep brrribbbitt. The most I've heard so far is a slight burp. They don't have a megaphone either.
I usually feed them in the morning between 9 and 11am. When I get off work 2nd shift they'll float in front of the glass and 'burp' like they're begging. When they see me looking they'll give another 'burp' then swim to where I put the crickets in and ;burp' again. It's so funny sometimes I'll give in and give them a few. ROFL
