When I first started keeping Apistos in 1992-93 I was given advice from
David Soares to keep a few males and females together. I didn't feel
comfortable with this after having spawned many fish during the previous
years before. I tried his way. I lost males and females alike. The dominate
males would kill the sub-dominate males and the spawning female would kill
any other females in the tank! I learned my lesson and decided to follow my
instincts from now on. The only exception to this rule was with my A.
steindachneri. Of course the dominate male killed the other 2 males but he
did spawn with each of the other 3 females who didn't bother one another. In
fact, who ever had fry at the time took care of the newer free swimmers. Who
knows?
Even with my corys, most of the time it is one on one. Now they don't kill
each other off like cichlids, but they do spawn much better at times when it
is 1 on 1.
Just my input.

Ken,
Never saw it with our nijsenni, however the A. swarzsaum (?sp, also aka =
black edged apisto), always spawned in duplicate. There were two females =
and one male and they would always spawn within one day of each other. =
The fry of these parents also did the same thing and I recall an article =
from Kurt Zadnick reporting similar findings.

I bought one male and two females to a 30 gallon tank. After two weeks they had formed a couple and the single female was
never allowed to go near the bottom. Both the male and the female would chase her away. After a month I had a very sick fish
standing near the surface gasping for air. I moved here. I didn.t think she got sick of being harassed so I bought one more
only to see the same thing happen with the new female. Maybe I just was unlucky and maybe the tank was to small for two
females but one thing is certain, my Nijsseni male is quite aggressive.

Hi
I've had 1m2f on two separate occasions. Both times the male spawned
with both females but he always stuck to his first lady, so no real
haremforming there, but not the strict monogamous either. Come to think
of it, I've never been successful with 1m2f. The only spawns that worked
were with 1 pair only, anyone else?
Just recently I noticed a similar behaviour with Ap. pertensis, a species
that is reported monogamous in literature. I had 1m2f in a 160L (40 gal)
tank. The male spawned with both females within 5 days. I had lowered pH
and both spawns were successful. One week after the first females fry were
free swimming he suddenly became very aggressive towards her so I had to
move her. Another week went by and he did the same with the second female.
He is now alone with 10 1cm long fry. A very recent spawn with a pair seems
to work a lot better so I wouldn't recommend 1m2f, YMMV though.

My experience with them was the dominate female chased the other female
until she passed away. I normally breed all my Apistos with one male to one
female because I have seen this tendency in many of my Apistos.

Fredrik,
I've seen this behavior in my wildcaught A.nijsseni male.I had a trio in a
larger tank(75g).My male spawned with his favorite female first and helped
her raising the fry.After the fry were about a week old another batch of fry
showed up in a corner of the tank.My male didn't help the other female at
all raising her fry.He just went over to her corner once in a while,checked
things out and then straight back to his favorite female.It was really fun
to watch.
