No, the great gradpa in the avatar is gone. He would be 15 year old if he were still alive. Their life expectancy averaged 8 year in my tanks. I am down to 2 males and one female from the 4th generation. I have no plan to multiply them as they have been inbreeding too long and I need to introduce new genes to the pool.
First generation, different broods. Second generation, mother and son. Third generation, brother and sister. The grandfather is a Malaysian import, already selected for the high body form.
