Since my auratus are never visible when they call, I've only been able to guess which are the males/females by body habitus. The males are more slender along their entire length, and the females have a rounder, fatter belly and tend to be a bit bigger.
I keep visible food in with the babies at all times and feed the adults daily, unless as someone else said, they appear to be getting obese, then I skip a meal or feed some livlier meadow plankton that they have to chase down.
Each fruit fly culture lasts about 30 days and I begin feeding from them after about 10 to 14 days. The cycle is somewhat temperature dependent and will slow down at cooler temperatures (below 70) as well as higher temperatures (in the 80's).
I use Reptivite(Zoo-med's), 2:0 Carnivorous Reptile Formula (T-Rex),ReptoCal(Tetra, Repta-Vitamin (Flukers) alternating them, with paprika added for the frogs with yellow and red coloration. Reptivite and ReptoCal are much higher in vitamin A, so I use these more sparingly. I always dust the fruit flies and crickets, but feed meadow plankton and springtails without dusting. This is just what has worked well for me.
