I setup a 40 gallon breeder for my soon-to-be colony. In the tank I had 2 female and 1 male. One of the females is 50 grams, and the other is 70. I started to notice weird marks on the smaller females back so I started to keep a sharp eye on them. One day I saw the bigger female chasing the smaller one into her hide so I immediately took out the larger female and put her into her own enclosure. They have been seperated for about 3 weeks now and she is eating like a champ again. She eats more than any of my other leos. I am hoping to eventually house my 5 females and one male in the 40 gallon breeder. Will bullying still be an issue once the two females are the same sizeweight?

What side is the hot side?

Although males are the sex known for fighting, females can also be territorial. Females that were incubated at high temperatures are known to be a little more aggressive than normal, and that may have something to do with it. However even females incubated at lower temps can get into fights with cage mates.

It is recomended to put together groups of females at a younger age, and then to introduce the male after all have reached breeding size. However this doesn't always work either. If I put together a group and they are incompatible, I usually sell off all of the females. That is unless they are pretty enough to warrent being kept individually for breeding.

I have one female that got really beat up by the females I put her with. The rest of the group gets along, but she was bit all to hell. I had to seperate her and have been nursing her back to health. She is now healed up and at a good weight, but I won't put her in a group again.

As others have said you may never be able to put to two females back together, just like humans, some of us never get along. Secondly, keeping the male in there all the time is a recipe to really stress your female(s). Someone else should chime in on the tank size, since I tend to err on the large size, but 40 gallons seems a bit low for the 5/6 geckos you plan on putting in there. I would say more like 4 only.

Do you have plan in place for all the babies?

I keep a good eye on them so I will only allow what successfully works as far as getting along is concerned. My male tried mating with the female but she rejected him for his first few attempts and he doesn't even try anymore. I have 3 other setups that are currently housing my sub-adults that will be used for babies.

For the person that asked, the warm-side is the side opposite the cave. The corner cave hide is the humid hide.
