Apistogramma tucurui

Jan,

This is a translation from Ingo Koslowski's paper Ostamazonische Apistogramma -
Aquaristische Neuheiten und Neuigkeiten, D.A.T.Z., 1994, v. 47 (12): 781-786:

    The Rio Tocantins, which enters the Rio Pará west of Belém and which in turn
empties into the Atlantic south of (the Isla de) Marajó was greatly altered in
the 80s by the construction of a gigantic dam impoundment near Tucuruí.  East of
this large impoundment Arthur Werner in 1987 found on the road between Jacundá
Nova and the dam a new Apistogramma species that is the most sensationally
exciting newcomer in this genus.  There, it inhabits almost exclusively streams
with sandy bottoms that are largely devoid of vegetation.  We are dealing with a
member of the A. regani-group that deviates from other known Apistogramma species
in its highly unusual markings.  In addition to large numbers of very small black
spots on the opercula, males have longitudinal stripes originating in the head
region that extend over the entire length and height of the body.  They are
formed by dark pigmentation between the individual horizontal rows of scales.
Other Apistogramma species usually only have abdominal stripes below a broad
body-long band that runs through the middle of the flanks.  The Tucuruí
Apistogramma, in contrast, has as many as seven in the head area and up to nine
longitudinal stripes along the flanks, even above the rarely visible lateral
band.  These are usually black, becoming wine red in aggressively displaying
fish.  The golden yellow head and ventral region, along with the bluish to
turquoise color on the posterior part of the body as well as the anal and dorsal
fin, make the Tucuruí Apistogramma one of the most beautifully colored species in
the genus.  Even the females exhibit the species diagnostic longitudinal bands,
but not as prominent nor as intense as those seen on the males.  The lateral band
is usually more prominent on them, and during the period of brood care dissolves
into a row of spots.  The lateral band is much more broad than in many other
eastern Amazonian species of the A. regani-group and is reminiscent in appearance
to that of the widely distributed Apistogramma eunotus of Peru, for example.  The
caudal fin of the Tucuruí Apistogramma has already been discussed more than once
in the hobby literature (DATZ-Redaktion 1988, Linke & Staeck, 1992, Schaefer,
1994)
    Breeding the Tucuruí Apistogramma is successful in slightly acid (pH 6.5) and
moderately hard water (10ºdGH).  This as yet scientifically undescribed species
exhibits an inordinately great intraspecific aggressiveness.  In a one meter
aquarium you can keep a maximum of one male together with two females.  Although
breeding the Tucuruí Apistogramma was consistently successful, and the fish had
been distributed fairly widely among Apistogramma breeders, the species
apparently is again missing from the hobby.  This is very unfortunate since their
natural habitat, presently known only from the area on the eastern side of the
Tucuruí impoundment, has in all likelihood been greatly altered and the existence
of these fish is possibly threatened by dam construction on the Rio Tucuruí.  The
last female known to me, which I had kept, was an exceptionally poor brooder who,
even though she would spawn frequently and the eggs developed well, would eat
most of the larvae the moment they hatched.  An oddity worth mentioning was a
female Tucuruí Apistogramma  that I kept in an aquarium with some A. geisleri.
She spawned with a male of this species.  The female even succeeded in raising a
few juveniles in the not very heavily decorated tank.  Some dropped due to
deformed scales and fins.  Other grew to a size which in many Apistogramma would
be sexually mature.  Astonishingly it was only males that reached this size and
then they exhibited none of the markings of the Tucuruí Apistogramma - like the
species diagnostic longitudinal stripes.  They closely resembled their paternal
A. geisleri.

Dear Mike, Jan, and folks discussing on A.sp. "Tucurui":

I've collected on Tucurui-area a couple of times, the last of them at 
past year.
The commonest dwarf cichlid in the area of Tucurui is A. agassizii (a 
population that we call "golden line"); Nannacara taenia is also found 
in sympatry with the previous species.
The so-called "Tucurui"-Apistogramma is not found on the dam itself, but 
near the town of Jacunda Nova (stated by German collectors and confirmed 
by myself) in opened swampy areas formed by overflow of streams 
(igarapes). Jacunda Nova is a town near the dam (the biggest city on the 
area is Tucurui).
It seems to be very rare in nature, as despite of intensive collecting 
efforts of three people, we could only collect about 20 specimens of it. 
The biotope is at no way polluted, quite the opposite, it is in a farm 
area.  Other fishes like tetras are commonest in the biotope.
It's not very difficult to breed, and we are presently producing it in 
our Apisto farm. Only point is that they are not raising many fry per 
spawning, unlike other members of the A. regani-group. 
The water we're using is pH 6.5, similar to the water found on its 
biotope (pH 5.5-6.0); it's NOT a blackwater fish.

Cheers, Marco.

Dear Jan,

At first the natural biotope is not disapeared, see my previous e-mail.
Water is tea-colored, with pH 5.5-6.0 (varied depending on the point of 
the swampy stream). An opened area, with Cyperaceae (aquatic plants 
Eleocharis-like) providing lot of shelter. Other fishes on biotope were 
some tetras. A. sp. "Tucurui" is not abundant on the biotope.
Yes, I also have same experience that they're very agreessive towards 
themselves.

Cheers, Marco.

Dear Bob:
the collecting point was told by me through a fisherman that collected 
there with Arthur Werner, which I guess was the first (or one of the 
first) to collect this species.
The dam is not that close to the biotope, so it seems not to be 
disturbed by it.
There are only farm activities in the region, and those activities may 
have perhaps altered the biotope, but I cannot assure it.  Normally farm 
activities include cattle farming, and for that purposes forested areas 
are cut to produce open areas, a need for grass growing (food for the 
cattle).

Surrogate mother update

by djhanson/calweb.com
Date: Thu, 07 Jan 1999
To: apisto/majordomo.pobox.com

> Anyone bred A. sp tucurui?
I did in the latter part of 97 that came from Germany. I had 4 that I
picked up at a Killi Mega Auction. There were sold as 2 pair. No. I
ended up with 3 males and one male! I separated the pairs into separate
10's. I noticed that in one tank, the dominate male was constantly
'going after' the other fish. I later lost this fish. In the other tank,
the smaller one was harrassing the larger one and I later lost that one
as well. I put the female with the other male with some live plants (I
don't remember what species)and a clay pot lying on it's side. They
spawned on the upper inside portion of the pot.

My water was straight RO water, pH 7.2 and the temp was 74. The fry did
hatch but I lost all of the fry. Don't go by my experience. You just
asked if any one had bred them. I hope someday to retry them and many
other Apistos when I have the space and time to donate to them.

Good luck.

I've, in water pH 6.5 and 4dH, which is the water in our farm.
With one pair per tank, eggs were removed as soon as seen, and 
artificially incubated with slow flow of water.
Young not difficult to raise on brine shrimp, and beautiful pattern they 
have is best seen in adults, juveniles are not as nice.

I guess you can make an argument for the correctness of the red/blue tag.
Males A. sp. "Tucurui" have some blue on the dorsal and anal fins and a
series of parallel reddish-brown dots. However, in the absence of another
color form I'll have to say that it's another selling gimmick. 

Helen then wrote:

Gary is right about the spotted scalares. This are common in the Rio Nanay,
Peru. I've also read a report in one of the Aqualog News mentioning a
scalare  from the Rio Negro with red caudal fins and, to a lesser degree,
red dorsal and anal fins. The author was John Dawes. I'd like to see this
angel.

Ap.Tucurui update

by "Helen Burns" <helen.burns/bigwig.net>
Date: Fri, 26 Mar 1999
To: "Apistogramma" <apisto/admin.listbox.com>

I would like to tell the list that my Tucurui parents successfully reared
their fry in my Uaru tank.  Yesterday the fry were 19 days old and I removed
them into a rearing tank.  The female was displaying to the male on
Wednesday and I noticed she was chasing the fry away.  No doubt another
spawning is on the way.

I found the parents to be excellent caring for their family.  Perhaps as
Mike Wise mentioned being housed in a large tank  was the answer to this
success.
Helen.

>From what I've read, A. sp. Tucuruí doesn't need special water conditions.
They just
don't like other members of their own species near their territory, unless
ready to
breed. Also the females are not the best at protecting their broods. Helen's
use of a
tank with a lot of bottom surface is a good idea. Let us know how your

To: apisto/admin.listbox.com

Dave,

If you buy them, the best way to keep them is 1 male to 2 (and preferably more)
females in a very large tank (4'/1m in length). The males are reported to be
totally intolerant of other male Tucuruí males and very aggressive to
non-breeding females. On the plus side, they do not require special water
conditions for breeding. Hope this helps.

sexing sp Tucurui

John,
When I was bagging my Tucurui young adults and sexing them, I studied the
caudal fin.  The male has spangling the female does not.  A magnifying glass
is essential while examining the caudal fin.
When you return on your wee 'trip' I would advise you to purchase, if
possible more females than males.  I had success with a trio (1 male 2
females) housed in a 39" x 20" x 16" tall tank sharing with a breeding pair
of Uaru.  I found the Tucurui to be excellent parents.
