Yeh I know about the size, but 15 minutes seems a little weird to me. Not all frogs are as aggressive as others when it comes to eating. Not to mention I have a fairly large tank in comparison to my RETF, so crickets seem to try to hide. On a side note I saw my RETF hunt last night. It was one of the most amazing things I have ever seen. I turned all the lights out. Any sudden movement in the thank the frog immediately took attention to and BAM, cricket was gone lol. I had to share that
