Two months ago one of my friends gave me Japanese Medaka and Kingyo fish. Some of Medaka had eggs. He told me how to collect eggs and I started to take care of these eggs. After a week the first two babies were born.
They were so tiny and translucent. And later I had more and more (up to about 30 in a day) babies. I made Medaka fishponds (Ikesu) by wine corks and Tofu package and floated them in a huge lily pot. Because grown-up Medaka and Kingyo fish eat these
babies, I had to separate them safely. Now the eldest babies are about 2 months old and 2 cm long. Because mother Medaka died a few weeks ago, all I have now are baby and kid Medaka. I am sure I was at the birth of more than 1000 babies, but unfortunately
now only a hundred are alive. I wonder if I keep them till they become parents and I get their babies.
