Albino Cory Eggs

[jb60083]

I have a pair of albino corys that just started to lay eggs. I have
read about how to raise the fry, but none of my eggs have ever hatched.


I have done a variety of things to help them along, such as putting the
eggs in a small plastic breeding area inside the tank, and arranging
the air bubbles so they hit the eggs.

I have left the eggs as they were on the glass and done the same.

And my latest attempt was taking the eggs out of the tank and putting
them in a glass vase with constant aeration.

In every case, the eggs did nothing. I waited 5 days for them to hatch.


I am beginning to wonder if the eggs are in fact fertilzed. Is that
possible?

Any ideas would be helpful!

Hi,

I recently had Cory eggs myself, as you may have read, all of them failed.
From what I've read Albino eggs are HARD to raise for some reason? compared
to say normal bronze or peppered, depending which albino species you have.
One suggestion I was given was to add some metheylene blue to the tank, it
helps fight the fungus.
I didn't have the money to buy any (damn Xmas!!) so the fungus got most of
mine,
or they were eaten but the other tank mates.

and did you heat the water in the vase? as the water needs to be at a
certain temp for the eggs to hatch, think its around 80C, not sure lol.

I hope you meant 80F :-),

I've recently hatched about 200 eggs in several different spawnings. I
didn't count the latest spawnings but about 2 months ago I had 88 eggs.
Maybe 60 hatched (it's hard to count that many little squirming fish!
They spawned again last night for about 30 eggs.

I run two ten gallon tanks for my Albinos. Both tanks share the same
filtration, water and heater. Within 1-2 hours of the spawn I gently
scrape the eggs off and drop them into the other tank. My eggs usually
take 6-8 days to hatch. I use NO fungucide Methyl* or anything. The
birthing / raising tank (same water as the adults) holds about 3" of
water at ~75F 7-9dKH ~7.4pH. I drop the water into the birthing tank so
that it creates lots of agitation and areation (running a pump and
siphon). Try to change 10% water about twice a week. The birthing /
raising tank is mostly bare bottom too, about 2 hours of lighting a
day.

If the eggs turn brown or any dark color, discard them. Milky
white/blue and sometimes a very slight yellow seems to be OK IMO. I've
tried the tupperware/jar and airpump thing... It didn't work for me.

If you'd like I can try to update my site with recent pictures. I need
to do that anyways. Check out what I have for now....... For what it's
worth. I'm not an expert, but what I'm doing is working for me :)

Wow, I am amazed at how quickly you all responded! This is my first
time posting a message in a group. Gotta love the internet. Anyway, up
until now, I have never actually seen my corys laying eggs. I read that
the female keeps the eggs between her fins and goes back over them with
the sperm from the male from her mouth, but what I witnessed was just
the first part - no fertilization. Also, I can't tell the two apart, so
up until now, I had no idea which was male or female. I thought the one
that was slightly bigger was female, but I was wrong. The little one
layed the eggs today. I find new eggs every couple of days, and I am
beginning to wonder if it is possible that I have 2 females. At any
rate, the platys in my tank love their new diet of fresh eggs. I am not
going to try to save any more until after the holidays, when I will be
home more to take care of them.

to tell cory's apart, its best done from the top, or a higher angle. the
female, will be the bigger and fatter fish. if they are similar sizes, look
just behind the pectral fins, the female will be broaded here than the male.
if the female is smaller than the male, you should try to imagine what the
male would look like at that size. this would give you a good guess at the
sexes.
