Bare with me here.....
I have a pair of adult gargs and began breeding them last year. My first 3 clutches of eggs were perfect, beautiful healthy babies. My 4th clutch...and sadly every clutch since then has molded around day 5. Literally NOTHING had changed. Temp, humidity, substrate, parents, containers....

So my first clutch from them this year, I experimented with 2 different cups and 2 different hatching substrates...moldy.

My only thought is one of my geckos became infertile for some reason and all of the eggs have been infertile to begin with. Thoughts on this theory??
