Ya I think i'm full. I know what you mean about mixing, but these africans get 12" to 14", and again they grew up together. Its funny when the two worlds meet each other its like they dont know what to think about each other. I did have to take out the big Trimac. It was picking on the female festae. I have a pair of Vieja agentea's growing out that might go in when i remove one of the festea males in a few months. Thats the plan any way.
