There are many beautiful dwarfs available at many local fish stores, but for their colors
alone many people are attracted to those of the Apistogramma genus. Many of those
offered for sale will live very nicely in most municipal water but breeding them is
usually a different story. Many require very soft acidic water which most of us do not
have access to. Then there is the Apistogramma cacatuoides- Hoedeman, 1951. Since
its discovery a little over forty years ago, the cacatuoides has been very
popular in the aquarium hobby because of its availability and ease of breeding. As I look
back on my records there are at least eight Apistos which I bred without Reverse Osmosis
water. Of those, the four that are available today are A. cacatuoides, A. macmasteri,
A. commbrae & A. caetei. There are others that will breed in harsher
conditions that I will list later.
For first time breeding, try to acquire about 6 juvenile Apistogramma cacatuoides
and place them in at least a 20-gallon "long" tank. Whatever your pH or
Hardness, I would leave it alone. No gravel and one or two more clay flowerpots than fish.
I use the small 3" clay flowerpots available at any garden nursery. With a round
8" carbide blade in a hacksaw handle, cut a ½" wide by ¾" high hole in
the top edge. Invert it in the tank and it will be large enough for just one fish to fit
in at a time. Now each fish has a place of its own in which to hide with a few extras ones
for an emergency getaway. Lots of Java moss and a large "bubble-up filter" will
be sufficient. I almost always feed newly hatched baby brine shrimp to all my Apistos
along with small amounts of frozen brine every third day or so. Never, that's NEVER feed
them live black worms from your local store or from anywhere as these will cause more
problems than you will be able to cope with. After a while you will be able to tell the
males from the females. The males will begin to color up and have small extensions on the
top and bottom of their tail. You will also notice an extension of the first few rays of
the dorsal fin which somewhat resemble the crest of a cockatoo and hence comes the common
name, "Cockatoo Dwarf". The female will have a yellow coloration and the front
of the ventral fins will become solid black. They are not normally aggressive so there
should not be much fighting.
If you happen to see a pair that seems to be keeping constant company, you could remove
all the other fish but I don't believe it's always necessary if you don't have another
tank available. Once you see the female has turned a very bright yellow color with very
definite black markings, it's a sure sign that she has laid her eggs. Some people argue
with me but I go right in and lift the pot slowly to see if there are in fact any eggs.
Bright fire engine red eggs are always a good sign. At a temperature of about 78 degrees,
the eggs should hatch in about 4 or 5 days but will only be little wigglers at this time
and the male will not be tolerated anywhere near the flowerpot. At this time I make sure I
have Java moss very close to the pot opening for fry food and a good place for them to
hide. In about another 4 or 5 days, if you are lucky, you will see the proud mother
leading her young fry outside in search of food. This is when she will become very nasty
and allow no one anywhere near her children. Now live baby brine shrimp should be fed
about 3 times daily in very small amounts. But also make sure you supply the others in the
tank with their share before a real fight breaks out. This is the time when the female is
the most dangerous and most deaths occur to the other occupants. You could possibly insert
a tank divider between them but I have found that sooner or later the fry find a way to
cross over to the other side and are eaten. The female most likely will watch over the fry
for about a month but in the meantime it is possible that the male will have bred with
another female and the process will begin all over again.
A little trick I have used often is when I notice eggs in one of the "caves":
I take a #1 cottage cheese container and lift the pot with eggs and female inside
and set it in the plastic container. Carefully I lift it all together and place it in a
waiting 5-gallon tank with water from the main tank and slowly lift again and remove the
plastic "transfer" container. Now I have just the female and her eggs all alone
in their own tank. This way I'm sure there will be no problems. I have also just slid a
net under the pot and transferred them that way but the female sometimes gets too excited
and eats her eggs. With the plastic container, neither the eggs nor the female are out of
the water at all. When the fry are able to take care of themselves, I return her to the
main tank for her to spawn again. I have always stated that there is no greater sight in
our hobby than a mother herding her children around the tank in search of food and each
night she will then return them to their home. Don't be concerned when you see her
"eating" them as she is just taking them in her mouth and moving them to where
she wants them.
Apistogramma cacatuoides is one of the Apistos that can be found in many
different color forms. With today's selective breeding you can find Double Red, Triple Red
and Orange Flash varieties. Double reds have red dorsal and tail fins with some black
markings. Triple Reds also have red anal fins with the markings and Orange Flash has solid
orange in all three fins. Because of inbreeding, an Orange Flash pair will most likely
produce fry in all three varieties.
Some others I have spawned recently without using RO water are A. borellii, A.
cruzi, A resticulosa and A. steindachneri. So whichever species you can find
in your local store or at a local fish club auction I would suggest you just maintain them
in your normal water and see what happens. Hey, you never know.
