I've seen a few posts regarding the eventual size of C. kelberi. I thought this might shed some light on the subject (as well as make your eyes bleed :grinno: )

Ichthyological Exploration of Freshwaters, Volume 17, Number 4, December 2006

A Review of the South American cichlid geneus Cichla, with descriptions on nine new species

Sven O. Kullander and Efrem J. G. Ferreira

Morphometry of Cichla kelberi

SL (mm) Min 48.1 Max 275.5 Mean 212.0 HT 275.5
Of 52 specimens collected, the largest was 272.5 mm (10.725 inches) with the average being 212.0 mm (8.26 inches)

Now that's not to say there aren't larger kelberi out there but based on the taxonomic description adult females max out at about 9".

For what it is worth, here is the original taxanomic description. Note the stated size of adult females and males.

Diagnosis.



Distinguished from all other species


of Cichla by presence in adults of small light spots

on pelvic and anal fins, and lower lobe of caudal


fin. Similar to C. monoculus and C. pleiozona in

possession of three dark vertical bars on side,

presence of a pronounced occipital bar in large
specimens, absence of black or ocellated markings
laterally on head, and presence of irregular dark
blotches on anterior abdominal side. Distinguished
from C. pleiozona by less scales in a lateral
row (76-83 vs. 84-93 in C. pleiozona) and
typical absence of bar 4.

Etymology.



Named for Dieter Kelber, in recognition


of his promotion of Cichla as sport fishes, and

for supporting our study with information and

images of the tucunaré amarela (C. kelberi) and

tucunaré azul (C. piquiti).









Geographical distribution



. Rio Araguaia drainage

and the lower Rio Tocantins drainage (Fig.

23). Introduced in reservoirs in Rio Grande do

Norte, Minas Gerais and Ceará (Chellappa et al.,

2003, as C. monoculus; Fontenele, 1948, as C. ocellaris),

in the Rio Paraíba do Sul (State of Rio de
Janeiro), and the Rio Paraná.
Kelber (1999) listed Tucunaré amarela from
the Itaipu, Porto Primavera, Jupiá, Três Irmãos,
Ilha Solteira, São Simão, Porto Colômbia, Volta
Grande, Jaguara, Estreito, Promissão, Igaratá and
Paraibuna dams in the Brazilian Paraná basin, the
Funil and Ribeirão das Lajes dams in the Rio
Paraíba do Sul drainage, the Xingó dam in the
Rio São Francisco drainage, the Pacoti-Riachão
dam near Fortaleza in Ceará, the Serra da Mesa
dam in the Rio Tocantins drainage. The Tucunaré
amarela corresponds to C. kelberi according to
photographs provided by D. Kelber.











Local names.



Tucunaré amarela (São Paulo,

Brazil; Kelber, 1999), Tucunaré comum (Northeast

of Brazil; Fontenele, 1948).





Notes.



Cichla kelberi has long been confused with


C. monoculus



(e.g., Fontenele, 1958, as C. ocellaris),


which it resembles in shape and general colour

pattern. We have not found any diagnostic character

other than the light-spotted pelvic, anal and

caudal fins, to separate the two species, but since

this character state is unique in the genus, we are
confident about species distinctness. The lateral
scale count is within the higher range of C. monoculus,
and below the range of











C. pleiozona.

The type material of Cycla toucounarai is represented

by two preserved specimens, MNHN

A.9490, labelled simply as coming from the

“Amazone”, although the description (Castelnau,

1855) also mentions











“le lac des Perles de la province

de Goyaz”, and the Rio Tocantins. They were

referred to C. monoculus by Kullander (1986). Both

specimens have characteristic blotches on the

abdominal side posterior to the pectoral fin base.

The larger syntype (Kullander, 1986: pl. 4 fig. 1)
is a male with nuchal hump, the smaller specimen
a female. The pigmentation of the smaller specimen
is slightly faded on both sides, and it shows
no traces of light spots on the pelvic, anal, or
caudal fins. The larger specimen possesses a black
occipital stripe, three prominent vertical bars
dorsally on the side, and trace of a dark blotch
dorsally at the root of the caudal peduncle. The
pigmentation of the right side is significantly
faded, but the dark pigmentation is relatively well
preserved on the left side. The anal fin is brownish
with indicated lighter patches distally on the
scaled portion of the anterior five soft rays. The
ventral half of the caudal fin is brownish with
indistinct lighter mottling but without light distinct
spots. The pelvic fin is brownish anteriorly
with two lighter patches on anterior soft rays. The
caudal spot is ringed with a prominent silvery
ring in both specimens.
Castelnau’s description and drawing disagree
with the preserved syntypes. The drawing shows
a specimen without occipital bar, and without
dark blotches on abdominal side, but with three
distinct vertical bars below the dorsal fin and one
anteriorly on the caudal peduncle, and some red
spots on the anal fin. The description apparently
partly refers to the drawing, but the total length
agrees with the larger syntype. Both syntypes
have D. XVI.17, the drawing shows XV.18, Castelnau
gives XV.17. He counts A. II.11, we count
A. III.11. The pectoral fin count, 14 is in agreement.
We count approximately 79 (larger syntype) and
71 (smaller syntype) scales along the midline, but
many scales are lost, and a through-going perforation
likely caused by an arrow or spear through
the larger syntype perforates the E1 row; Castelnau
gives the range 72-75.
In the description, Castelnau says that “l’anale
est piquetée de rouge et de noir”, i.e., the anal fin
is spotted with red and black. This is significant
because C. kelberi is diagnosed particularly by its
anal fin colouration. One of us re-examined the
existing syntypes with special emphasis on the
possible presence of spots on the pelvic and anal
fins, which were not mentioned by Kullander
(1986). Whereas the pigmentation on these fins is
indeed not uniform, we cannot recognize light
spots of the kind displayed by some freshly preserved
adults of C. kelberi although the silvery
caudal blotch ring is well preserved in the syntypes.
Close to imperceptible light mottling of the
otherwise brownish scaled portions of the pelvic,
anal, and caudal fins does not permit ambiguous
identification as homologous with light spots in
fresh specimens of C. kelberi, and is at least
partly referable to lost scales. The light anal fin
patches are located anteriorly on the fin in the
transition between the scaled portion and the
scaleless margin, a condition which is different
from fresh specimens in which the light spots are
located on the posterior soft rays. Whereas the
light mottling of the anal fin possibly can be correlated
with the red spots described and figured
by Castelnau, it does not match the white or yellow
spots observed in fresh preserved specimens
of C. kelberi, and is doubtfully distinct from uneven
artifactual discolouration of fins in other old
specimens of Cichla.
Whereas the larger syntype has 79 scales in
the E1 row, which is in the upper portion of the
range of counts of C. monoculus and near the
median of the slightly higher range of C. kelberi,
the smaller syntype has 71 scales, which is far
below counts observed in











C. kelberi, and near


modal for C. monoculus.


Castelnau (1855) included material from several

localities in his concept of C. toucounarai. He

relates that he first saw this fish in the lac des

Perles in Goiás, later it was found in the Tocantins,
and finally in the “Amazone”. “It is known locally
everywhere as Toucounarai. The Chambioas
of the Araguaia gave it the name of Kini-teray.
Its flesh is very good, and it reaches sometimes
double the size that we have indicated.” [Translated
from the French.]
Castelnau (1855) expresses that he hesitates
to describe C. toucounarai as a new species because
it would be very close to C. monoculus, differing
by the constant absence of spots from the abdomen,
assured by observation of an “immense
quantity” of individuals of C. toucounarai. It would
be close also to C. flavomaculata but differing in
the absence of yellow spots from the body and
the colouration.
Quite clearly, the description of C. toucounarai
includes observations of











Cichla from the Tocantins,

Araguaia, and the rest of the Amazon. The syntypes

seem to have been preserved from the

later part of the expedition, from Western Amazonia.

The sketch for the drawing may have been

made in the Tocantins basin, or the colouring of
the plate based on field notes from the Tocantins
basin. We also suspect that Castelnau may be
including C. piquiti in his concept of C. toucounarai.
That species does not have dark blotches on the
abdominal side and is quite common in the Tocantins
basin.
Cichla kelberi











frequently displays black blotches

behind the pectoral fin base, like the syntypes

of C. toucounarai, but in contrast with the drawing

and description. The anal fin spots are white,

yellow or silvery, not red. Species of Cichla frequently

display some red colour on the anal fin,
but not in the form of small spots.
Even specimens of C. kelberi in a poor state of
preservation may maintain light markings in the
anal fin. Inasmuch as the syntypes of C. toucounarai
do not display anal fin markings, and since
the description is ambiguous and may refer to
three or even more species, we continue to consider
C. toucounarai











a synonym of Cichla monoculus.

To fix the name, we select the larger syntype

of C. toucounarai as lectotype. It can be recognized

by the morphological information above, and is


figured by Kullander (1986: pl. 4 fig. 1).



Are your eyes bleeding yet?? LOL :nilly:

Yes but bleeding in a very good way. Thanks for sharing this information. Some interesting discriptions and some little known information that I did not ever read before. SWEET! :headbang2

P.S I know you have more info.:naughty: I spent the last two day's going through a lot of your conversations (post) on the other site... you know which one. ;)

interesting read.
but some part of me still tells me mono size...
I don't know. I highly doubt a mono female would be mature and breeding at 9". I agree that kelberi might get a tad bigger than indicated but I think 14"-16" is a max.

Gorgeous fish. I've contemplated selling mine several times but always decide that I'd be kicking myself if I did so. Besides, I don't think anyone would pay what I wanted... LOL

Why did you sell yours?

I wouldn't have sold mine if I had it. I would have just threw the Ray in with them or just go grab another tank.:D But that's me.
