Hey all! I got my first amphibian last night, a beautiful pacman

1)Now I haven't completely measured (letting the little guy settle in) but it appears to to be about 3" SVL. I just did a little. Peek in and heard a very very faint sound. Upon listening closer it was almost a chirp? Now I know it's a bit small still be is my research correct in that that is a female noise?
2)specs of tank: aprox 78 F, aprox 88% humid. 10 gallon, touch less than 2" of Eco earth. Corner water bowl, silk aquarium plants (cleaned with piping hot water.)
(Getting better gauge in two weeks)
3) shop only fed mice. I know that should truly be a max of 1/month due to fat content. Ill be feeding night crawlers & crickets dusted with vitamins 1/week and calcium every other feeding or so.
How am I doing? And is there any personal experience you can give that might add to my researched knowledge? Thanks!!
