Believe it or not, the first pic, the cichlid farthest right that's kinda turning, I brought home and introduced into that tank when he was about half an inch long. Pet o Rama gave me him free because he was getting picked on in their tanks and I though it was worth a shot since Ihad a ton of hiding spots. He's done great and is almost adult sized now. I have another full grown kind of him, and they dug out the nest but never laid eggs unfortunantly.
