Update on my babies: Still lively and beautiful! Need to takes some pictures of them to post, will get those up soon. I officially have two boys and six girls! They were obvious to my after the first boy got big enough. He had a much longer tail than the rest and his nails were slightly longer. Also the girls are growing much faster in size than their brothers. I do have one runt that is the same size as the boys but doesn't show any male attributes. Going to keep an eye on her.

Oh, and of course boys are separated from girls.
On a sadder note, I lost a baby a few months back... I woke to find its head had been sucked into the intake of my pump... The piece that covered the intake was easily kicked off by mom and I would put it back on every time, but I wasn't there and tragedy happened... I now have it secured with tape that I replace every time I clean the pump and it doesn't slip off anymore. I hope this educates others to be more careful in future, as I now am... I have noticed that the Marineland piping usually has this issue after months of use. They just don't hold securely anymore. Like maybe the pipe wares away or the water expands it...
My babies are Judith aka Judy aka Jude (8+ years), Biggie aka Big Girl aka Bitter (1+ years), and Yella (1 year? by size)!
