A. reticulosa - whitewater?

by Mike & Diane Wise <apistowise/bewellnet.com>
Date: Mon, 13 Jul 1998
To: apisto/majordomo.pobox.com

According to Kullander's original description, A. resticulosa was collected by H.
R. Axelrod, J. Géry, and others (= H. Bleher, A. Schwartz, & G. van den Bossche)
on the Igarapé Xicanga, a tributary of the Rio Madeira, about 5 km (3 mi.) west
of Humaita and in a drying pool 18 km (11 mi.) west of Humaita.  This drying pool
is probably one of the over flow pool caused by the damming effects of the road
bed of the Transamazon Highway.  Axelrod gives a detailed description of these
backwater (not blackwater!) pools in his article(s) on his trip on the
Transamazon Highway in TFH, Feb & Mar 1977.  The only mention of A. resticulosa
in this article is a single sentence:

"Adolf took the Corydoras back to show his father, and I took some new dwarf
cichlids, a pair of angelfish and six feet of something the Indians smoke!"
(Hmmm?!)

Other than mentioning that these pools collected lots of fine silt and clay (=
white-water?), nothing is said about the water chemistry in Axelrod's article.
All Kullander says is:

"The Rio Madeira is a white-water river, rich in suspended matter, … For most of
its course it flows through Tertiary sediments, but the uppermost course is over
Archaic rocks and is characterized by a series of falls extending upstream from
Pôrto Velho to Guajará-Mirim on the tributary Rio Mamoré and to Cachuela
Esperanza on the Rio Beni (e.g. Pearson, 1937).  The major rivers of Bolivian
Amazônia are the principal tributaries of the Rio Madeira, but many tributaries
also join along the Brazilian course, including several from Brazilian shield."

All this tells us is that the Rio Madiera, itself, is a white-water river that
draws its water from several sources.  Streams coming of the Brazilian shield
(below Humaita) are typically clear-water streams.  Those originating in Tertiary
(volcanic) areas are typically white-water streams.  Still, this doesn't tell us
anything about the Igarapé Xicanga.  I would imagine that A. resticulosa, like
other members of the resticulosa-complex, is a clear/white-water species.
Perhaps Marco Lacerda, who collected this species at the type locality might know
more.

Steph,

It all depends on which "A. resticulosa" you get. There have been several species
in the hobby lately (A. sp. Wangenflecken, A. sp. Blauglanz, and the real
resticulosa). The species pictured & discussed in the books of Schmettkamp,
Linke & Staeck , as well as the photo in Mayland & Bork's book are of  A. sp.
Wangenflecken, BTW. Let's assume that you do have the true resticulosa for now.

> Preferred water conditions maintenance/breeding

Mayland & Bork list the following for the Rio Xicanga, the type locality of A.
resticulosa, as follow:

pH: 5.92, Conductivity: 17µS, Hardness: <1ºdGH & 0.31 dKH

> lone female borelli

This isn't a very large apisto, growing to about 6 or 7 cm (<3") and hasn't
bothered other fish in my experience.

> Breeding patterns - harem or pair, aggresiveness etc

Being a regani-group fish, it is a casually monogamous/opportunistically
polygamous species. This means that the male doesn't put a lot of energy into
defending a large territory. They seem satisfied with a single female (my male
would drive my lone female crazy, at times, with his courting) but probably would
be happy to service several females.

They should be a "moderately easy" fish to breed at a pH <6.5 and moderately soft
water (dGH<3; dKH<2). I know Ade Lau, Laramie Wyoming, has been successful with
them in the same water conditions that he keeps his Discus.

Not common, but not rare either.

I got mine directly from Marco Lacerda at the Chicago ACA convention in 1997. If
I remember correctly they were US$10 each, but shipping & other costs will affect
their final retail price. Only you can decide if AUS$50 is unreasonable or not,
but it's close to what mine sold for.  Hope this helps.

I can echo Mike's comments and add a little more info.  The fish Marco was
selling were labeled A. resticulosa "Humaita".  Mine proved to be very
prolific in pH 6.2 - 6.8, and moderately hard water (I've forgotten what my
hardness is, I just remember it fell out as moderate on the scale). I kept
3 pair in a 29 gallon tank. There were spawns constantly and the males
tolerated each other.   A significant percentage of the fry were
successfully raised in the tank.  I still have several of the original fish
I purchased in Chicago as well as many of their offspring and their
grandchildren?? as well.  Marco was selling these fish for $12.00/pair but
I doubt this has any resemblence to the cost one would incur in shipping
these fish from Germany.

Hi,
        I kept my pair in a lightly planted 10 gal tank. I used RO water
with 10 ml black water extract added to the RO water. The pH is around 6.2
and TDS 70 ppm. I feed them frozen bloodworms, frozen brine, whiteworms,
microworms etc. The male is about 2.5" while the female is only about 1 in.
They spawned regularly and right now, I have about 6 3/4 in frys in a 5 gal
tank and about 25 4 weeks old frys in a breeder net with their parent. My
male actually don't do much courting and the female do all the dancing and
brooding. When she had frys, she will not let the male get close. Well, here
she goes. The female is back into the cave and that means they will spawn
again. Hope this help.
