Two of my Angels are in the process of laying and fertilising 300-500to
eggs
on a leaf in my 50gal tank. I've bred Angles before (this pair were
two of
the 40-50 that I reared); I've set up a small bottle of distilled
water to
hang in the tank and treated it with a drop of Methylene Blue to
prevent
Algae growing on the eggs. The bottle also has an air stone at the
bottom
provide a constant flow of water over the eggs. This technique workedespecially
well
before; once the fry had hatched I then transferred them to a 5gal
tank on
the 5th day, just before they started free swimming. They were then
fed
daily on live brine shrimp and I carried out a partial water change
each
day.
I would be very interested in any suggestions others might have who
have
experience in rearing fry; any useful tips etc would be welcome,
over the coming days/weeks.

Letting the parents raise the fry can be extremely interesting. Also,
to
make sure the fry aren't sucked up
into the filter, I take a foam block that is used for the inside of the
filter and cut a slit in the small end with a
sharp knife then slip it over the intake tube. I raise baby angels and
sell
them to the local pet shop for $1.00
a piece.
I found with all the fanning and mouthing that the parents do with the
eggs,
and then the wigglers, that fungus
isn't a problem for me. As soon as I see the first free swimmers I
start the
brine shrimp. Of course not all pairs
are good parents but watching them herd the little ones around and
defend
them can be very entertaining.

I would also suggest that if you try allowing the parents to rear them,
that you reduce the level of acoustic noise inside the tank (eliminate
the filter splash and turn off any airstones). The parents communicate
to the fry and each other using vibrations in the water produced by their
pectoral fins. When it works well, it is fascinating to watch, but when
their communications are drowned out by mechanical noises, they just get
frustrated. Angelfish aren't the best parents to start with, so no need
to make it harder for them, by making them 'shout' over the noise of an
airstone.
Also a dim night light will simplify their job of keeping the fry
together. You are emulating moonlight, and without it, in total
darkness, the parents are again frustrated and the fry wander everywhere
and into hazards.
If the parents are jittery, placing cardboard around the tank will
eliminate bothersome and distracting shadows, and they will feel more
secure (close static borders). Don't forget to cut yourself a few peep
holes before installation. hth
Nice touch, Max - the acoustic communication thing. Something I've
often wondered about, I won't ask your sources on this on. Makes
sense, that's good enough.
I've always raised my eggs and fry away from the parents - in my new
setup I'm looking at a 20 gallon for spawning and rearing together.
It's a 20L instead of a 20H, so will depend on the size of the parents
if it will be adequate - I have my eyes open for a 29 that I might
just happen to find sitting on the sidewalk waiting for a home. Maybe
a yard sale.
Good Luck, Andrew - sounds like fun. Mine are just quarter sized at
the moment, so it will be a little while before I catch up with you. I
use MarOxy instead of Meth Blue, it's colorless and I can see better.
