I used to have 2 leopard geckos, Stella and Melina, in the same tank but when then newest baby Lindsey came, Melina started getting a little mean. She was very bigger then the other 2 so i decided to take her out and separate her. That was a few month's ago and now that the baby is bigger i want to re-introduce Melina but am to afraid. Should i keep them separate because Melina is still very much bigger then the other 2. Also, Lindsey has become slightly aggressive when its feeding time. They get fed every other day and when i try to give Stella something, Lindsey tries to bite her. Any advice?
