I have spawned borelli in 5 gallon tanks in my garage.  The tanks had 
just a sponge filter and was filled with Java Moss from top to bottom.  
I used pure R.O. water and a handful of garden variety peat thrown into 
the tank.  I think the privacy that they got from the dense cover of the 
Java Moss and being in my garage helped a great deal.  Diet at that time 
was almost 100% baby brine shrimp.  If the borelli are well fed and have 
a good deal of privacy, spawning does not seem to be a problem.  I 
believe the dense cover provides privacy for the female from the male 
and vice versa, thus lessening domestic strife.  It also provides more 
safety for the fry from the male.

Maybe not so strange

Your female borellii is acting quite normal. I have found that it is much
easier to remove the female and let the males grow up where they are. As for
her actions - she is ready to spawn again and should be placed with the male
again. She is chasing her young because she sees them as a threat to her new
offspring. (Even though she doesn't have a male to spawn with.) The female
will quit caring for the fry at about the time you're talking about.

I spawn my pairs in 10 gallon tanks with just a sponge filter and a fine
layer of fine sand with some bulb plants and a small flower pot. The plants
then are easily removed. Still, the best bet is to remove your female to
another tank.

<<             I need help this time understanding what's wrong with my
 Borellii female.
 This is the first time I raise fry in the same tank living the offsprings
 with the female.
 I noticed a good growth rate but I think problems are now coming up.
 The eggs hatched 26 days ago and now the fry are getting bigger really fast
 but the problems is the female. She stopped her parental care 10 days ago
 and layed new eggs 5 days ago. The eggs died because I took out the male
 several days before because it was dangerous for the fry. The female didn't
 care about the eggs and she seems to be newly interested in her 22 days fry
 but now she is acting very strange towards them, she doesn't seem to want
 to eat or fight the fry but she scared them swimming towards them very
 rapidly. I'm thinking that maybe she is starting defending her territory
 also against this little fishes.Maybe this behaviour its not so strange I
 was waiting for this to happen but I didn't think so soon.
 
 Now the big problem is taking them out of this tank the fry are little,
 fast, and too many for  me I need a good system to take them out. I cannot
 siphon them out because they are fast enough to swim away from the plastic
 tube. The tank in wich they are its also heavily planted, so it's really a
 big deal.
 
 What do you think? 

Simone,
    Once the female is ready to spawn again, she will leave her fry and
spawn.  One interesting thing I discovered is that once the female has
spawned the first time, she does not always wait for a male to join her.  She
will defend the territory around these new eggs as though they were viable.
 But in a couple of days, they will turn white, and she will eat them.
    The 23 day old fry are in danger at this point.  If you have another tank
suitable for the female, I would recommend moving her, as she is easier to
catch.  Otherwise, you may have to take out the plants to make catching the
fry possible.  At 22 days, they should be able to take handling with a net.
 A brine shrimp net may be safer, ad there are pores, but no holes.  You
might try 2 nets, using one net to chase the little guys into the other net.

My name is Kaycy. I too have spawned the 'borellii'. I used a ten gallon
tank for one pair. Fine layer of sand. Because they are cichlids and like to
move their fry around in pits. I buy bulk dry plant bulbs and let them grow
in the tanks. I also have my pH at 5.0. I use an R.O. unit for all my
apistos. I don't use dither fish because the way my tanks are set up - side
to side - on a rack, the apisto 'next door' gives the same effect as using
dithers. It's a lot safer for the other fish too.

I don't know if this helps you, but it is another way of breeding apistos.

holes in the gravel in wich they move their fry periodically, the gravel

Borellii's prblem solved

by "Simone e Pierluigi Vicini" <psvicini/mdnet.it>
Date: Sat, 1 Nov 1997
To: "apisto" <apisto/listbox.com>

Hi everybody I hope my experience can be usefull to you.

So I had that problem with my Borellii female and I wrote to the list
trying to understand why she was behaving like that.
Now I know why?
I set up my new tank one week ago because I had an algae problem that I
couldn't solve, so the only thing was to take down everything and start
again. I love aquarium plants so I'm trying to have good results with them
and with my apisto.
So my tank was set up again one week ago and my three Borellii at first
were shocked for the new set up infact the female didn't have its territory
signed now.
The male was very aggressive and the female couldn't take a place in the
aquarium because of this male.
I knew she was going to breed.
So the day came and the female was not ready with her territory.
The male bagan to follow her in the aquarium showing his fins waiting for
the spawn, but the female was ready but scared and she did not feel safe in
that condition so she  waited for the spawn  till night. In the meantime
she
layed in the grownd in a bunch of Limnophila, she changed her color from
bright yellow to plae white-yellow.
She layed eggs at night but during the first morning she ate all the eggs.
Now she is yellow again and preparing for the next spawn, she will have
time to set up her territory again.

Thank you all
Bye

A. sp. "opal"

Gary-
The "opal" is now identified as a wild color variant of A. borellii.  By your
experience, it is safe to say that the opal color is recessive to the dominant
blue/yellow.  It looks like the aggies aren't the only ones with color
options.  Henry Ford once said, "give them any color they want, as long as
they want black."  I guess Ma Nature was not one of Henry's role models.

Gary.......I've spawned 2 gamillion A.borelli over the last several
years, from the "yellow/blue" form to the "opal" form to the "red-faced"
form, and all of the babies have come out a bunch of each!!!!!
Now there is NOTHING scientific from this ......maybe my strains were
imperfect to begin with, but I got ALL forms from ALL of the
spawns...regardless as to what the "originals" were sold to me
as.....and boy did I ever get promises along those lines!!!!!

The Tetra book says that the different forms live "sympatically".....my
mama always told me to never use a word you can't spell.....boy would
that limit me!!........but that means they are all in the same pond in
nature.........someone else kick in here.  But understand that it is
difficult to tell if you haven't kept or kept track of you fry to
adults....I did that....and with A. borelli that's a long time.

I never had something like that. I mean that even if I have some Borellii females
in the tank with one male when they spawn the female guards the eggs and does not
let any other fish to come near the breeding cave. So she started fighting with
the male and with all the other females.

But also this happened to me and maybe can help you:
One of my Borellii female eats her eggs twice and the reasons are these: the
first time I had a lot of fry born three weeks before this happened. The female
guarded them until she was ready to spawn again. She started to fight the fry and
to try to take the male near the cave  but the male was, I think, annoyed by the
fry so he did not spawn but only get near the female.
She layed eggs and she started to take care after them but the day after this the
eggs started fungus and die even if the female tryed to take care of them but
soon the eggs disappeared.
The second time I was setting up the tank again because of an algae problem the
female was very annoyed by the changes of the auqarium set up and she layed eggs
on a leaf of Echinodorus. The male spawn with the female but the day after she
ate the eggs.

I saw this: good Borellii's eggs are of a very bright orange if they are not
fertilized by the male the day after the spawn they loose all their brightness
and started falling off from the place the female attached them.
I f you see again that another juvi female eats the eggs of your good mom try to
take out all the juvi except for the mom and maybe for the dad before the eggs
disappear.

Once my spawning Borellii female layed eggs on a breeding container where I put
the male because I saw him eating the small fry born from the previous spawning.
She layed eggs right on one side of the container in wich the male was caged
hoping that he could fertilize them. When I saw this I said to myself "WOW HAVE
YOU SEEN THAT? HEY DON'T DO THAT AGAIN."
It was just incredible.

Nick, 

This is a junior name (old name) for  A. borelli. Gives us a short
description of your fish to see if we can help you determine if it is A.
borelli.

Folks.......I've had 5-6 batches of A. borellii in he last 1 1/2 that I
chose to keep and raise..........I experienced the same thing that Eric
did with the borellii.....SMALL babies after a year.  Folks these aren't
in a 10 gallon.  They are in a 125 gallon and get feed 2-3 times a day
with live bbs and live black works.  Two of the batches grew just fine

Believe it or not, try adding finely ground basic flake food. I have had
growth spurts with my young apistos that did the same thing. Once I
figured out just adding basic flake to the diet, I would feed the fry
the first couple weeks with the live BBS and then started adding the
basic flakes and didn't have a problem with the growth rate. I think
that feeding them just the live BBS and worms is still lacking something
in the diet that the basic flake gives them.

This is just something I tried and had luck with it.

borelli

by "Sanford, Dave LHS-STAFF" <SanfordD/issaquah.wednet.edu>

To: "'apisto list'" <apisto/majordomo.pobox.com>

hi, My borelli seem to grow about as fast as other Apistos, and faster than
my nijsseni.  I feed primarily bbs, but lots of it.
Also they get a squirt of daphnia with cyclops(there are always tiny ones
they can eat), and I agree with Kacey, a pinch of finely
ground flake is good.  I use earthworm flake that someone suggested several
months ago.

Hello Dave
I've had Opal in the past and spawned them, got rid of them because i

Ken,
I remember reading about the A.borellii "opal" in Uwe Roemers book.I think
he wrote that the "opal" is  an aquarium bred strain developed in former
east Germany .I don't have the book with me at work.I will double check
tonight. Maybe MW can help us out with this?

New picture up.

Max,

You are correct. Uwe says that A. sp. Opal is a domestic aquarium strain
originating from the DDR (former East Germany). They apparently were line bred to
reduce the amount of yellow on the body. Koslowski, however, considered A. sp.
Opal as any red masked blue A. borellii, be it wild or domestic. Staeck reports
that he found such "super" specimens of A. borellii mixed in with normal forms
wherever he collected them. A. borellii also seems to have more blue in the
southern part of it range & more yellow in the northern part, but that no color
forms are completely isolated.

Opals and Red and Black apisto

by Mike & Diane Wise <apistowise/bewellnet.com>
Date: Fri, 23 Feb 2001
To: apisto/listbox.com

Daryl,

The original A. borellii (Opal) strain was produced in the former East Germany
(called Opalita) using highly colored "super" specimens. I wouldn't call them a
rarity, but the original pure Opal strains that produce mostly Opal offspring are
becoming rare. They are still around and available in the the US. A few wild
caught Opal specimens can be picked out of any shipment of wild imports. I am
sure that wild Opals produce off colored forms - since we probably don't have
inbred "super" specimens. When these wild "super" males (or females) are bred
with inbred Opals you just have to expect some odd combinations.

Your Red & Black Apisto is not a normal commercial or common name. It sounds like
a name made up just to make them seem different. They could be anything. 90% of
all apistos have red and black markings, so this fish could be anything.

Borelii 'yellow point' spawn

Yes, but most females will reabsorb the eggs if there is no male of her own or
closely related species to stimulate her spawning urge.

>
> 2. who should care for eggs - female alone or both parents?

All apistos are maternal egg brooders. The are reports of A. borellii  males
taking over brooding larvae (pre-swimming fry) if the female is lost. It is
uncommon, however.

I doubt that they would interbreed. They are very different fish. I certainly
wouldn't keep these two species together. Male A. steindachneri are among the
largest apistos out there. I've had males exceed 4"/10cm TL. A. borellii males
rarely get larger than 2"/5cm. A territorial A. steindachneri can easily kill any
A. borellii. We are dealing with territorial cichlids, after all. Just because
they are small doesn't mean they won't behave like other larger cichlids.

>
> 4. How sensitive are borelii to pH and hardness? I mean, for breeding?

A. borellii is a savanna apisto and can reproduce in slightly basic, moderately
hard water (pH<7.4, ~12ºdH. If you can get your A. cacatuoides to successfully
breed in your water, your A. borellii should be successful in the same water.

pH sexratio Pelvicachromis

To: apisto/listbox.com

Yes, I agree with you there. A. borellii is a weird little apisto. It comes from a different
climate zone, for the most part, and even has different behavioral and brood color patterns
compared to most apistos. That's why it's been placed in a species-group all by itself.
