Fry Observation and a question

Charles,

Before you make a decision on the fry let them grow up
a bit. When they are very small it is hard to
distinguish all you need to see. Also, view the fry
from the top not just the side, because what may look
like a single tail from the side may just be something
different when viewed from the top.

The genetics of Goldfish is pretty complicated. If the
backs are crooked or misshapen, just discard the fry.
It has also been found if that water has been two cool
during the development of the fry in the egg increases
the tendency for single tailed fish no matter the
variety that are bred.

Also after the fry are hatched the water must be kept
very, very clean. Fry are really susceptible to
ammonia and nitrites and many people make the mistake
thinking all those little fish can't produce that much
waste, but it is surprising that they do. Even the
eggs themselves emit ammonia into their water while the
embryo is developing, which is why a lot of fry die
after hatching because the water has waste ammonia in
in it. Water for eggs and fry must be carefully
changed all the time and you certainly should have
airstones in the container of both eggs and fry.

Good luck.

Ah, thank you.

I might disagree with the "unfortunately" part, I don't care for the
distorted shapes. As soon as these resolve their health problems they
are going back to the dealer.

I am "hospitaling" a few fantail goldfish, and they laid some eggs. I
took the chunk of algae the eggs were in to another tank that had been
pretty much idle.

I have seen 24 fry so far, and not one with a double tail. Seems like
there should be a few, anyway.

they all are straight, like normal goldfish. When do fantails develop
the distorted body shape? Or do I have a bunch of normal fish now?

thanks
