My method is probably not the best in the world, but it works well.  I have
about a 90% survival rate among my fry.

As soon as I notice eggs, a insert a divider in the tank, giving the parents
and fry as little room as possible without scrunching them up to tight.  This
keeps the other Cichlids from eating the fry, and protects them from the VERY
aggressive parents.

I usually leave the parents with the fry for at least a week.  They keep the
fry in a close bunch and keep them from slipping through the cracks between
the divider and the sides of the tank that I can never seem to get rid of.

After some time, I remove the parents to the other side of the tank, and let
the fry stay for about another week.  After that, I net them and move them to
another tank to grow.

There are many reasons for my methods.  I find that the fry grow faster
without their parents and provided with all the baby brine shrimp I can
supply.  If I try to take them out too soon, they are a pain to catch.  With
all of the gravel in my tank, they just hide in little spaces and I can't get
them.

I've tried moving the parents to a breeding tank, with no gravel, just wide
open spaces, but they hated it and would not breed.  They were very nervous
without the presence of the other fish, and swam into the walls trying to get
out whenever I entered the room.

Like I said, it's probably not the best method in the world, but it works.

You know, in spite of what the books say,  I've heard this same complaint
from friends who have tried keeping bettas with other fish (I've never
kept them myself). In one case, a betta kept pestering a much larger fish,
which put up with it for quite a while before getting fed up. It then turned
on the betta and killed it. Can't recall the details (like the species of
the other fish). Looks like their behavior is not as predictable as some of
the books would have us believe.

Went to the National Aquaria in Baltimore, MD this weekend.  What can
I say?  It's a very nice place and don't hesitate to go, just go early!

They had all the what I suppose are the usual trappings of such aquaria:
big, big saltwater tanks (one full of rays and another doughnut shaped,
you walked down the inside.. neat!), smaller tanks and interesting 
bio systems like the Chesapeake bay biotrope.  

But what really caught my eye were those poison arrow frogs.  I don't 
ever recall seeing them in the flesh, just some fuzzy pictures.  Wow!
Are they ever colorfull or what!  They looked better than some marine
tropical fishes.  I was tentative in including them in the next "big"
tank endevor but not anymore.  Well, just a tad, it's those crickets.
Seems like I'm locked into either growing them myself (yech) or weekly
trips to my local, sleazy pet store for my "Bag O' Crickets".

At least I'm not starting on this tank for (hopefully) many many moons.

I have several such tanks.  They all have one thing incommon: a very high 
ratio of plant biomass to fish.  I find that it's much easier to keep a 
tank like that completely unfiltered than underfiltered -- plants happily 
eat up ammonia, but are not as good at dealing nitrate and even worse at
handling nitrites.

I have been following this note string with interest.  Allow me
to make a point, site a out of focus example, and do a IMHO.

Do we know the true surface area of George and Robert's tanks?
Are there plants in the tanks?  Enough plants could possibly provide
enough surface that no other bio filter would be required.
(This could give the phrase 'dead biofilter' a new twist.)
George tends to fill his aquariums with plants.  
Did Roberts tank have plants in his?  

The summer of 1971 a 20 gallon long aquarium in my high school science
lab was left unfiltered for the summer.  The tank was dense with plants
and contained mostly livebearing fish.  I do not recall how may fish
were in the tank.  Most of the water had evaporated by fall and some
fish were still alive.  Upon return the science teacher added tap water
to top off the tank.  I am sure that the pH of that tank was quite low
compared to the tap water.  Perhaps the fish were tougher back then.

IMHO:
I have found that ammonia is easier to keep in check then nitrite
in established tanks.  It seems that it takes less surface area to 
maintain the bacteria for ammonia-nitrite then it does for the 
nitrite-nitrate conversion.

There are undertank heating pads - I use them for my main 4 ft tank:
they are cheaper than heating coils to buy, and no more expensive to
run than the usual coil-in-glass-tube  heaters. Some say that they are
dreadful - that they leak heat all over the place, dreadfully
inefficient, etc. Well they need a good insulation under the pad, but
you'll be putting a piece of polystyrene or carpet there anyway - just
put a thicker piece - and yes the tank bottom has to heat up, but
once the system is set up and in stable equilibrium, there is no extra
heat loss because of the greater insulation under the pad. Everything
is out of the water (except the thermostat of course) and they are
guaranteed for ages. A firm in Scotland makes them and, damn it, I
can't remember the details, but they are at home.

>Do inverts and corals generally breed in a reef tank environment?

I'll take a shot at this one.  All soft corals in my tank have
reproduced, some to almost plague proportions, asexually.  Steve Tyree
has had a Goniopora (stony coral considered very difficult to keep)
reproduce asexually.

Sexual reproduction is more difficult to achieve, if you actually want
juveniles.  My open brain has spawned repeatedly in my tank and I have
reason to suspect other have too.  However, it's difficult to know
becuase the eggs/planulae are very small and easily overlooked if you
don't know exactly what to look for and when.  Raising the eggs and
planulae is still very difficult.  There are some shrimp and clam
farms but no coral farms yet.

So, to answer your question, lots of things are reproducing asexually,
some, perhaps many, things are spawning (sexual reproduction) but
raising adults from the spawn is very difficult and requires a lot of
knowledge, patience and some luck.  Oh, time and money, too.

Tetras need specific water conditions and specific set-ups that minimize
egg and fry predation.  Without these factors the breeding of tetras is 
difficult.

A lot of tetras are still caught in the Amazon delta and imported.  This is
in part because many tetras are sort of like the piscine equivalent of
roaches and breed in huge numbers, in part this is because they are cheaper
to catch in Brazil than to raise in US or Indonesia.  If carefully managed,
the supply of the wild tetras can be sustained and harvested forever, but 
deforestation, polution and over-fishing may destroy theor populations.

>Are tetras still difficult to breed ?

Depends on what tetras you have in mind.  Some are very easy, some are not.

Until this week I had a 10 gal tank with free-spawning Flame Tetras 
(Hyphessobrycon flammeus).  In it I had a large pillow of Java moss, 1/4" of
peat moss on the bottom of the tank instead of gravel, a layer of Salvinia 
at the surface, and a small Tetra sponge filter.  The water was moderately 
soft (30ppm-100ppm depending on the season) and neutral to acid pH (7.0 
down to 5.5 depending on the hardness and the freshness of the peat).
The tetras spawned in the Java moss, ate the eggs and fry they could reach,
but enough fell deep enough into the moss to hatch and grow into something 
not so easy to catch and eat.  

The other tetra tank I have is the Lemon Tetras in the tank in my office.
It's a 10 gal with one AquaClear 150 and one AquaClear 200 filters (now set 
to minimal flows, so they chop up fewer hatchlings).  The decor is a huge
piece of driftwood, some Java moss, a large bare-root clump of Anybias nana.
The water is very soft (17 ppm), slightly acid (6.8 pH) bottled drinking 
stuff.  I have a couple of dozen fry of various sizes in the tank, so I
introduced a "biologocal control" into the tank: a few small Aspidoras
catfish.  

In both of these tanks the tetras spawn(ed) continually and the fry survived
due to a sufficiently dense refuge of Java moss.  The fish were given a
large enough space to swim and interact, so they did not constantly menace
the spawning sites.  One tank was under-filtered and very acidic, the other
is drasticly over-filtered and near neutral pH.  In one tank the fish 
got a lot of live foods, in the other tank the fish mostly get flake food
mix.  

Try a healthy group of flame or lemon tetras -- in my experience they are 
not difficult.

"Huge fish kills linked to slumbering algae"
"Once awakened, microbes release toxin in estuaries, scientists say"
Boyce Rensberger, Washington Post staff writer

"Lurking on the bottoms of estuaries along the Eastern  Seaboard,
scientists have discovered, are countless numbers of "phantom"
microbes--a form of swimming algae--that can burst forth from a
state of suspended animation, swim up into the water, release a
poison that kills fish by the millions and then retreat into
hiding within hours.

Researchers say the mysterious creatures have been responsible for
a least nine major fish kills in North Carolina's Pamlico Sound,
which lies inside the Cape Hatteras National Seashore, and in
nearby fish farms since May 1991.
<.....>
This past January, the organisms killed tens of thousands of
striped bass in a North Carolina fish farm that had  used water
from the Tar River, which drains into the sound.
<.....>
The alga (singular) is a one-celled organism that appears to spend
most of its time dormant inside a thin shell, or cyst, resting on
the bottom.  Burkholder has kept dormant algae alive in tanks for
nearly two years.
The signal to emerge appears to be an unknown substance released
into water by fish.  Aquarium experiments show that the cysts will
hatch if the researchers simply pour in some water from another
aquarium containing live fish.  Within minutes if a cyst is young
(days if it is old), the shell cracks open "like an eggshell,"
Glasgow said, and the alga swims free.
<...>
The newly hatched algae swim up into the water, multiply in great
profusion by ordinary cell division, and release a toxin that
kills the fish in massive numbers.
<...>
Within an hour or two of the last fish's death, the swimming form
of algae fall to the bottom, secrete a new cyst about themselves
and again go dormant."

Go for it!  I came very close to doing the hydroponic with tank water thing.
Purchased the plants, the window box container but decided not to as they
would take up nutrients which I really wanted to go to the "real" plants in
the tank.  They get their tank water but only during water changes! 
(Used tank water is a miracle drug for house plants.)

I have a cut leaf philodendron root stuck into a 75 gallon plant tank and it
has probably reached the bottom of the tank by now.  I think that such a system
would be more useful for a tank which does not contain a lot of plants due
to the nutrient problem mentioned above.  Your silver dollor may nibble 
the coleus roots, but probably not a thicker root system like philodendron species.
And unless it, the fish, dies, who cares about a coleus?  Just try another species.

Another neat plant to try would be the chinese evergreen.  It is described 
in one plant book as something which one can grow underwater!  I would
be a tad nervous about poison but not a lot... don't know about coleus per se, 
but you might try reading a book on house plants.  They will sometimes warn you
not to let children nibble, but they rairly mention fish. (grin)
