I just uploaded some adolescent pictures of him when he was actually green in the same album as linked in my original post . Not sure why he's so dark now. Saying he out of habit, no clue what sex it is. Neat frog, its croak is very guteral low and loud when he/she decides to croak. Sometimes I'll see him in the water side of the tank for weeks on end, other times, he'll bury under the leaf litter and chill out eating everything that crosses his path.
