Pair of M.ramirezi
Microgeophagus Ramirezi originates from the Llanos.The Llanos is
the savannah grasslands of the central Orinoco drainage in lowland Venezuela and Columbia.
M.ramirezi is also found in the upper part of the Orinoco delta. It is not an
Amazonian fish. This beautiful South American species has many names. It is known as: Ram,
Butterfly dwarf cichlid, German Blue Ram, Papiliochromis ramirezi and Apistogramma
ramirezi. The scientifically correct name is Microgeophagus ramirezi
according to Dr. Sven O Kullander, Senior Curator, Dept. of Vertebrate Zoology, Swedish
Museum of Natural History.
My first encounter with this colorfull and popular species happened many years ago. The
owner of my LFS (Local Fish Store) managed to breed the German Blue Ram, a colorful
domestic bred strain of Microgeophagus ramirezi, in one of his tanks at home. He
had one gorgeous male left which I had to take home. Unfortunately, it took a while before
I was able to find a female for him. A few weeks later the same store got a shipment of
German Blue Rams in. I bought two good looking females with bright pink bellies. Those
females were very short lived. Unfortunately, I ended up buying more females everytime
they got a shipment in.
Ending with the same results, the females usually didn't last longer than two months. I
found out later that those Rams were mass produced in Asia. Asian bred Rams are usually
loaded up with hormones to stimulate egg production and to make them look really good
right out of their shipping bag. Adult Rams show their best colors only after they have
settled in their new environment and feel secure in it. Juvenile Rams don't develope their
full color until they they're sexually mature. Stay away from young specimens that look
great in the dealers tanks. Most Asian Rams are infertile and not suitable for breeding.
I decided to stay away from this species because of the above mentioned problems. I chose
to keep the similar, not as colorful, but less sensitive German Rams bigger brother, the
Bolivian Ram - Microgeophagus altispinosa instead.

I just recently got interested in the German Rlue Rams again and decided to give them
another try. This time I wanted to make sure that I'm getting pairs of either wild caught
or domestic bred stock. I found two different sources for domestic bred Rams and bought
three pairs from each source to begin with. They were kept quarantined in a 30g holding
tank for two weeks just to make sure that they didn't carry any diseases. A bonded pair
was chosen out of the three and moved to their own 10g tank. You can tell that a pair has
bonded when they seem to stick more together. They will also team up against other fish
and chase them away.
Female M. ramirezi
1 st day
It took my pair about a week and a water change before they decided to clean a spot on top
of a pebble. Male and female spent a lot of time cleaning their chosen spawning site. I
knew then that something was going on. Sure enough, I found a medium size clutch of about
100 eggs on the pebble later that afternoon. This was the pairs first spawn. According to
Linke and Staeck's book "American Cichlids 1: Dwarf Cichlids" M.ramirezi
is known to produce clutches of more then 200 eggs! Unfortunately I was unable to watch
the actual spawning. The color on the male and female really intensified after they had
spawned. My pair are still juveniles and I expect bigger spawns in the future. I tried to
get some decent shots of the spawning site. Unfortunately the pair chose a spot in the
back of the tank[stinkers:)], getting clear macro shots from that distance was impossible.

The one thing that stood out right away was that male and female where taking turns
fanning and guarding their eggs. This is a different breeding behavior then eg.
Apistogramma families where the female guards the clutch and the male guards the
surrounding territory.

The female moved all the eggs/hatchlings into a pit in the back of the tank ,behind a
piece of driftwood. I was able to tell later that the eggs had hatched by some short quick
swimming motions of the wigglers. Again, male and female took turns guarding their
hatchlings. When one partner left the wigglers the other took immediately over. The
temperature was moved up to 84 F at this time to ensure fry survival.

3 rd day
The male started attacking the female really badly this morning, so I moved her out of the
breeding tank and back into the holding tank. This makes me wonder if the same thing would
have happened in a bigger tank than in my 10g tank?
5 th day
I usually don't get too excited anymore breeding my fish , but today was truly a fun day.
I witnessed 3 of the fry free swimming this morning. The very excited male went straight
after each one and picked them up with his mouth. What looked like fry chewing turned out
to be some kind of cleaning attempt .He spit them out at the same spot where they were
picked up, he then went straight back to the pit to clean the rest of the fry. The fry
already lost their yolk sack and it was time to feed them their first Infusoria* and
Microworm meal. This is also a good time to start a new batch of Baby Brine Shrimp(BBS).
The fry will be able to eat freshly hatched BBS in a few days from now.
6 th day
Wow, what a surprise this morning. I got my first glance at all the youngens. The male
paraded/guarded a fairly large school of very hungry fry around the tank . The tiny free
swimmers seem to be a little bit bigger than Tetra fry. I fed them a squirt of Microworms
which were eagerly eaten, followed by another squirt of fresh hatched BBS. Some of the fry
ate a few shrimp, but it seems that the Artemia nauplii is way to big for their
tiny mouth right now. I'll continue feeding a mix of BBS and Microworms. I was amazed by
the movement of the youngens. They are all over the place and the male has a hard time
keeping them together. He goes after every stray and picks them up with his mouth to spit
them back into the group. I managed to get some pictures this morning: Male with a school
of first day free swimming fry.
So far everything seems fine. I made a 25% WC this morning due to heavy feeding of
Microworms and BBS. It was fun to watch the male attacking the vaccum tube.He really went
after it and even got caught inside the tube. He really turned out to be a good father and
guards his fry around the clock.

10 th day
Last night, 20 min. before lights out, the male decided to dig a new pit in front of the
tank. He used his caudal fin almost like a shovel to form a 1.5" diameter, 1"
deep depression into the sand. You could literally see the sand flying .The whole school
of fry was let into the pit for "bed time" after the male finnished digging .
Unfortunatley, I was unable to take photos of the actual digging but managed to get some
shots of the male in the new pit surrounded by youngens:

12th day
The temperature in the tank was gradually lowered back to 81 F. The fry grew to almost
double their hatching size now. I noticed this morning that the fry were staying very
close together near the substrate and weren't following the male as much. I don't know if
this behavior is temperature related or caused by the fear of predation by the camera or
me. A second pair started to show breeding signs in the holding tank this morning. The
females belly looked very plum and pink. I moved the pair to a similar 10g tank that was
set up in expectation of the next spawn last night.

14 th day
The fry are growing at a good pace. Everybody eats BBS now. I stopped feeding Microworms
to keep up water quality. BBS live up to 12hrs in a freshwater tank. This ensures a
constant food supply for the youngens. I squirt BBS in the tank twice a day, mornings and
evenings, three hrs before the tank lights go out.

15 th day
The fry are growing into the typical Ram body shape. Their bodies are still transparent.
My wife and I are amazed at the fast growth now. We can really tell the difference in size
from morning to evening.
17 th day
I moved the male out of the breeding tank . He seemed to have lost his interest in
guarding the juveniles. The usual attacks of the vaccuum hose stopped during my biweekly
25% WC's. The juveniles reached about 5mm TL and are now ready to survive on their own.

21st Day
The juveniles reached about 8mm in total length. They are still growing strong. They were
fed a mix of crushed flake food, BBS and Cyclop-eeze for the first time this morning. I'll
wait one more week before they will be moved to a larger grow out tank. I'll move my
breeding pair back into this tank once the juveniles are moved to their new quarters. I
hope you enjoyed this breeding journal and that it will help you to breed this very
colorful and interesting species someday, too. Note: I probably raised over 1000 ram fry
since this article was written. I still enjoy finding a new batch of eggs deposited on a
pebble or a turned over flower pot in my tanks. It's still quite a challenge for me to
raise Ram fry from eggs to a sellable size. I changed my breeding technique to a more
commercial approach nowadays and hatch 90% of the spawns artificially in specially setup
hatching and grow out tanks. I also noticed that I got much better hatch rates by using
straight R/O water in my breeding and hatching tanks. We keep our line of Rams strong by
adding new blood every year to avoid inbreeding.
*I always keep a handful of Jave Moss in all of my breeding tanks. The micro organisms
aka Infusoria found in the Java moss make an excellent first meal for hungry small fish
fry such as Ram fry.
The breeding tank setup
Size: 10g
Water specs.:Ph 7.4,TDS 120ppm
Spawning atTemp.81Deg.F Rearing: 84F following Mike Jacobs earlier suggestions on the
Apisto list Substrate:Pool filter Sand
Decoration: Planted driftwood, one flowerpot, three granite pebbles
Plants: Java fern, Java moss, Anubia var.barteri, Babytears, Echinodorus tennellus
This is a picture of the 10g breeding tank.
The school of fry is above the pebble on the right. The breeding tank was set up as
natural as possible with intentions to witness Microgeophagus ramirezi's quite
interesting natural breeding behaviors and to get good photographic results. Tank Size 10
- 20 gallons a pair for breeding. Larger community tanks for keeping several pairs. Rams
do great with Discus and other South American Dwarf Cichlids. Recommended Breeding
Conditions TDS<80ppm, Temp.81-85 Deg. F. ,PH <7.0 Note: We keep the fry in our
hatching tanks until they are big enought to be moved to larger growout tanks. All our
hatching and growout tanks receive 50% Waterchanges with either pure R/O or special
filtered / aged tapwater. All our fish get the highest quality frozen, live and dry foods.
