Hello, I am new here and fairly new to having geckos. We inherited two geckos last summer when a family member passed away and left them behind. We did some research and found they were not being housed properly so we made adjustments and they have been doing well. They are in a tank that is 30inches by 12inches. Well last night we had a knock on our door and a friend of a friend dropped off two more geckos in a smaller tank saying he was moving and desperatly needed a home for them. We have taken them in and they are both females although one is much smaller then the other, would it be safe or a good idea to add them to the larger tank with our male and female. we would prefer to have one tank if that is possible but we are still learning about these cool little guys and dont want to do anything wrong. We are not breeding our original two and have no intention to start doing so, would that be an issue with three females with one male? Worried about the small one being bullied as we have no idea if it is small because of age or because of not getting food. Thanks for anyone that can help us with this.
