Finnaly the first one hatched, there soo tiny and it changed color from light to dark red as soon as I moved some algae in the net breeder to get a better look. How do I know which of the eggs are empty, they all still look inflated.
I would keep them as seperated as possible, for Ive seen babies from the same source act much differently then other eggs. Like Righty says, Ive kept even 10 in one breeder with no problems..
However, I just watched a batch of 10 babies from the same source as yours all eat each other and they were divided 2 per breeder...I also have read similar experiences from others that bought from the same source..
