5. How I raised him:

6. How I raised him:
Jeffery started out in a petri dish and that’s
where he lived until hatching. Every day
(except weekends) I would take him out of
the dish, look at him through the
microscope, take pictures and videos that I
needed, change his water (which was natural
spring water) and put him back in. This gave
him what he needed to grow up and hatch.
After hatching I let him free in a small public
tank with other fish so he could be with his
friends. I first got him on April 2nd and he
hatched on April 11th.

36. Farewell

37. Farewell
Jeffery is all grown up now
and on his own. It seems
like yesterday that he was
in his little embryo. He is
now swimming with his
friends having a good
time. It was a hard and sad
moment, but I knew it
was better if he was with
other medakas swimming
free.
