Hey everyone, this is my first post. I have a group of 4 dendrobates auratus bronze and turqoise, they are about 9-11 months old. They are not particularly bold, still hopping away as I come near. However in the recent months one of the frogs is always out, not moving if I come close. He/she is always the first to eat and seems to eat much more than the others. I feed daily once usually but twice every other couple days. The others do come out as well and they all seem to interact. I'm wondering what may be causing the individual to be particularly bold, perhaps female or male? And any tips on sexing for this species would be much appreciated.
