Very nice and healthy frog.
Seems to be a male to me.

I fed my Pyxie until she was 3 inches lenght 3 to 4 times per week : crickets, locusts, roaches, nightcrawlers and baby mices.
What is important is to give various preys to bring it all it needs and don't forget also to dust with calcium 1 to 2 insects per week and with calcium + vit D3 1 insect every 2 weeks.
