New Pixie

[Jace]

I put a hide in my tank when I first got mine, but he ignored it. They do tend to dig themselves down a bit, or under things. As long as you have enough substrate for him, I wouldn't even bother with a hide.

A hide is optional as long as there is enough room to burrow. I prefer hiding places, however, because the frog seems less stressed.

From the pics shown, it looks like you have a male. As it gets older and we have more pics it will be easier to tell for sure.
