Size difference

Hey guys do these two have too much of a size difference to be housed together? And One is male and one is female, will he try to breed her even if he hasn't reached maturity yet? The male is the smaller one. Still looking for my scale to weigh them as well thanks guys

There are various reasons not to house younger crested together.

One the size difference will cause bullying, which means one of the gecko will not eat as much and her growth will slow down.

You also do not want to house a male and a female together unless the female is proper weight and also has a good calcium reserve.
