And don't guess the weight if you aren't sure.... get a scale and make sure that they're big enough before you do any damage. Especially if you really have a $3000 enigma.
You will see many breeders who are in a rush to produce the next amazing morph and will breed females at 40 to 45 grams. I believe This is a big no no as they are playing with the geckos health. I make sure my female geckos are the minimum of 55 grams, I prefer 60 to 70 grams. Now males on the other hand can be 45- 50 grams because they do not deal with the stress the female does. Just be careful not to over breed him. I usually wait until my males are 50g plus. and yes it is true, the bigger the female the more eggs she will lay. I like a nice fat tail about the thickness of my thumb before I even think about putting male and female together. There is no rushing in reptile breeding. You have to be patient, let the geckos grow nice and big before you breed. You'll be glad you did.
