Missed the last reaction. No typo at all. Eight years old is recommended, expecially females. I've aquired 3 juvies, also from 2009. I think 2 of them are females, but I'm affraid that 1 of them is a male. It's to early to say, because they are aquatic for a short period. I also have a female from 2007 now. That could result in a 5.3 group, but I'm still hoping for 4.4. Pics will follow soon.
