Hi thanks for the great advice!
I am 100% sure that they are a male and female pair as the male calls constantly in the day(s) before what looked like amplexus.I only have the two frogs and eggs were laid. A clutch of 4 eggs were deposited the day after I saw the wrestling/amplexus/whatever it was!
I don't have a mist system hooked up to the viv although a repti fogger is in place which keeps the humidity very high; if this is enough to keep the eggs hydrated I don't know so I will lightly mist the tank each day.
I won't take any pics for a few days until I know if the eggs are fertile or not. They are in very clear view so if they begin to develop I will certainly know. I must admit I have my doubts. I take it Oophaga Pumilio can lay unfertile eggs anyway? I know they feed unfertile ones to tadpoles.I will post how the eggs and frogs are doing over the following days, keep an eye on the thread!
Thanks again
